The building is the only one in the United States that has been erected solely for use as a Horological school. When the Bradley Polytechnic Institute was opened in 1897, in Peoria, and affiliated with the University of Chicago, the most significant action of the trustees was the incorporation into the plan of the institution of the Parsons Horological School, which had existed for eleven years and ranked as the leading watchmaking school of the country. The significance of the action lay in the intention to teach specific trades in addition to technical skill. The Horological School, fully equipped as it was, and with a 100 students enrolled, was taken as it existed and made a model of the numerous special trade schools that were later added to Bradley.

The IMP was a genuine mechanical computer. From the sole solenoid actuator's incremental motion, the horological mechanism derived irregular oscillating functions which in turn rotated the globe and varied its axis, and also moved its two cylindrical indicators for longitude and latitude. Some uncommon, intricate horological devices found in the IMP include cardioid-shaped cam discs, a cone-shaped cam cylinder with a cardioid cross-section and "mechanical rectifiers" which transformed an alternating motion into an analogous, but unidirectional motion (see illustrations). The only other electric actuator used in the IMP instrument was the motor used to fast-forward the mechanism from the actual point-to-nadir to the expected landing point, some 120 degrees further east.

The museum was founded by Dr. Roger W. Robinson and his wife Imogene, collectors of Willard clocks, after they were able to acquire the Willard homestead. For a period in the late 1990s the museum was administered by the National Association of Watch and Clock Collectors, but soon was turned into an independent foundation again, governed by a board made up of representatives of the Willard family, the founding couple, the local community and some horological experts. The original homestead farmhouse have been added to in recent years and in addition to the original rooms there are now two large galleries. The museum has over 80 Willard clocks, representing the craftsmanship of all the members of the family in the horological trade.

Frodsham died of liver disease in 1871, and was buried at Highgate Cemetery, London. His obituary stated that ‘during a long and honourable career, he distinguished himself by his devotion to the science of horology, which he greatly advanced, and his clever works upon the subject are regarded as authoritative by members of the trade.’ Charles’ son Harrison Mill Frodsham (1849–1922) took over the firm, following in his father’s footsteps by publishing his own theoretical horological material, including an important series of articles entitled ‘Some materials for a Resume of Remontoires’.Harrison M. Frodsham, 'Some Materials for a Resume of Remontoires', Horological Journal, Vol. 20 (1877-78), 21-23; 49-53; 66-67; 76-79; 86-88; 104-105; 120-122; 130-131; 163-165. Vol.

A chronometric singularity (also called a temporal or horological singularity) is a point at which time cannot be measured or described. An example involves a time at a coordinate singularity, e.g.a geographical pole. Since time on Earth is measured through longitudes, and no unique longitude exists at a pole, time is not defined uniquely at this point.

In 2015, Stas played a substantial role in the introduction of the "Horological Smartwatch", a smartwatch design that uses a secondary analog dial rather than a screen for its display – giving the timepiece a more classic look than other such devices. The Horological Smartwatch product line included models for both the Frédérique Constant and Alpina watch brands, and used "MotionX" core technology licensed from the California-based company Fullpower Technologies. It was developed in a joint venture known as Manufacture Modules Technologies (MMT). In 2016, Aletta and Peter Stas sold their watch brands to Citizen, creating a high-tech collaboration in development of electronic, mechanical and hybrid calibres combining Frederique Constant’s high-end Manufacture capability with Citizen’s long history in revolutionary solar, radio and ultra-thin calibre innovations.

In 1892, Lydia Bradley, of Peoria, Illinois, became interested in the school, and being desirous of assisting deserving young men and women who wished to learn the trade, offered to provide a larger building together with all necessary equipment. Arrangements were accordingly made and in 1892 the school moved to its new quarters, in a large building in Peoria, Illinois, formerly occupied by the Peoria Watch Factory. The school was still called "Parson's Horological School," but was under the management of Parsons, Ide & Co. Parsons, Ide & Company of Peoria, Illinois, incorporated to conduct Parsons' Horological Institute as a school of theoretical instruction in watchmaking, jewelry manufacturing and optics, and to manufacture jewelry, special instruments, and so forth. The capital stock was US$120,000 and the incorporators were James R. Parsons, Fred F. Ide and Lydia Bradley.

In 1970, the kinetic sculptor Rowland Emett was commissioned to design and build a "water-powered" clock known as The Aqua Horological Tintinnabulator. The clock was installed in late 1972 and chimed on the hour and half-hour, playing "Gigue en Rondeau II" (1724) from Rameau's "Pieces de Clavecin" Suite in E minor. This musical animated sculpture was originally located on the lower mall and was a popular meeting place.

The Dover Castle clock was initially dated in the 14th century, only to be later revised to around 1600. In 1993, Christopher McKay organised a symposium with the Antiquarian Horological Society to determine if the clock could be dated to 1386. The majority of participants voted for it to be the original, but roughly 1/3 of participants voted the clock to be of a much later date.

People interested in horology are called horologists. That term is used both by people who deal professionally with timekeeping apparatus (watchmakers, clockmakers), as well as aficionados and scholars of horology. Horology and horologists have numerous organizations, both professional associations and more scholarly societies. The largest horological membership organisation globally is the NAWCC, the National Association of Watch and Clock Collectors, which is USA based, but also has local chapters elsewhere.

David Salomons, Breguet 1747-1823 (privately published, 1921), p.46 Breguet's most remarkable piece anticipated the wristwatch by a century; he designed this, together with his friend John Arnold, for Caroline Bonaparte, Queen of Naples, in 1810. Many honours recognised his enormous contribution to horology. Each watch from his workshops demonstrated the latest horological improvements in an original movement, mostly fitted with lever or ruby-cylinder escapements that he perfected.

David Robertson (1875 – 1941) was the first Professor of Electrical Engineering at Bristol University. Robertson had wide interests and one of these was horology – he wanted to provide the foundation of what we could call “horological engineering”, that is, a firm science-based approach to the design of accurate mechanical clocks. He contributed a long series on the scientific foundations of precision clocks to the Horological Journal which was the main publication for the trade in the UK; he and his students undertook research on clocks and pendulums (some funded by the Society of Merchant Venturers); and he designed at least one notable clock, to keep University time and control the chiming of Great George in the Wills Memorial Building from its inauguration on 1925, for which he also designed the chiming mechanism. Today, we get accurate time from atomic clock ensembles in observatories round the world, compared and distributed by GPS satellites and over the internet, and displayed on almost any public or personal screen.

Robey, J.A., "Iron Crossings and Brass Rims", The Horological Journal, British Horological Institute, Newark, England,July 2015 Brass alloys were then called latten, and it seems likely that brass clocks would have been called "latten clocks" (or "latten horloge" or "latten uhr" in the native languages) to distinguish them from iron clocks, and that "lantern" could be an English interpretation or corruption of latten. The other is that the name derived from the shape; the clock resembles a rectangular lantern of that period, and like a lantern was hung on the wall. In inventories of deceased clockmakers, lantern clocks are usually referred to as "house clocks", "chamber clocks" or simply "clocks", since in 17th century England they were almost the only type of domestic clocks that existed. It was only after a century had passed, when other types of domestic clocks began to be used in British houses, that more descriptive names for it appeared.

His career was cut short when he was accused of embezzlement and the house was bought at auction in 1801 by General George Harris, for £9,000. His descendants continued to live at Belmont, the clock collection being assembled by the 5th Lord Harris, who served as the first President of the Antiquarian Horological Society, for which Jonathan Betts acts as Curatorial Adviser. The house is now held by a trust established by Lord Harris.

In 1783, an admirer of Marie Antoinette, the Queen of France, commissioned a watch from Abraham-Louis Breguet as a gift for the Queen. The requirement was that the watch should be "as spectacular as possible, incorporating the fullest range of horological expertise known at the time". There was no time deadline or financial limit with the commission. The final product was the Breguet No.160 grand complication (Marie-Antoinette pocket watch).

The clock was re-discovered in the tower in 1928 by T.R. Robinson, an horological enthusiast who went up the clock tower to see the new clock (installed in 1884). The presence of the old clock was known to many, but nobody attributed much importance to it. It was only T.R. Robinson who believed that it was the clock mentioned in 1386. From photos taken in 1928, it looked to be fairly complete.

Clock tower The National Watch and Clock Museum was founded in 1977 by the NAWCC and over time has put together a major collection of horological artifacts, mainly clocks and watches, but also related tools, machinery and ephemera, and has become an important institution in its field. Most of the greatest and most important clocks and watches ever made have been preserved and exhibited — for decades if not centuries — as decorative art in such major museums around the world as the British Museum in London or the Metropolitan Museum in New York, or form a small department in the globally important museums of technology and science such as the Smithsonian Institution, the Musée des Arts et Métiers or the Deutsches Museum. There are only few museums like NWCM, dedicated principally to the history of timekeeping, and the majority of them - located in former centers of horological production - have primarily a local or regional focus. Since the former "Time Museum" in Rockford, IL closed in the 1990s, the NWCM is often described as the broadest specialist horology museum in the country.

Frodsham was awarded the Telford Gold Medal from the Institution of Civil Engineers for his 1847 lecture on the laws of isochronism. At the Great Exhibition in 1851, he was awarded a first- class medal for his timekeepers. The firm won fourteen further medals and honours at the major international exhibitions over the rest of the nineteenth century. At the 1862 International Exhibition, Frodsham not only exhibited but was also one of the jurors, writing the detailed horological section report.

Three of these timekeepers travelled with the explorers James Cook and Captain Furneaux during their second voyage to the southern Pacific Ocean in 1772–1775. Captain Cook also had Kendall's first timekeeper on board as well as one of Arnold's. Whereas Kendall's performed very well and kept excellent time during the voyage, only one of Arnold's was still running on their return to England in 1775.

Therefore, there has been a great deal of debate over who invented the spring detent escapement, Arnold or Earnshaw. This argument, first initiated by Earnshaw, has been continued by horological historians (such as Rupert Gould) to present day. However, the argument is irrelevant. In recent years, research has established that Arnold's success was not due to the form of detent escapement, but to his original methods of adjusting the balance spring for positional errors by manipulating the overcoil terminal curve.

One of the oldest existent star maps in printed form is from Su Song's (1020–1101 CE) celestial atlas of 1092 CE, which was included in the horological treatise on his clocktower. The most famous one is perhaps the Dunhuang map found in Dunhuang, Gansu. Uncovered by the British archaeologist Marc Aurel Stein in 1907, the star map was brought to the British Museum in London. The map was drawn on paper and represents the complete sky, with more than 1,350 stars.

Henry Graves Jr. died in 1953. His daughter Gwendolen inherited the Supercomplication and in 1960 passed it to her son, Reginald ‘Pete’ Fullerton. In 1969, Fullerton sold the piece to Seth G. Atwood, founder of the "Time Museum" and an industrialist from Illinois, for US$200,000 (equal to some US$1.2 million today). After that, the watch had been kept in the Time Museum in Rockford, Illinois, one of the leading horological museums in the world, which was shut down in March 1999.

In 1971 the Museum published a broader study by Beeson, English Church Clocks 1280–1850: History and Classification. This led the AHS in 1973 to form its turret clock section, of which Beeson became chairman. In 1972 Lord Bullock, Vice-Chancellor of the University of Oxford opened the Museum of the History of Science's Beeson Room to house its horological collection. For his final book Beeson returned to one of the castles in France that had interested him and T.E. Lawrence as teenagers.

Daniels' mechanism has since been described by some as the most important development in horology in the past 250 years. Although the horological industry was first introduced to the concept in 1976, Daniels' escapement was met with scepticism and lack of interest. It was not until the 1980s that Swatch Group chairman Nicolas Hayek adopted the concept, using it in his upmarket Omega brand. The company unveiled – to great acclaim – its first automatic watch using Daniels' coaxial escapement at the 1999 Basel Watch and Jewellery Fair.

In retirement, Woodward wrote another classic book, My Own Right Time fondly known as MORT, a record of his passion for horology. Along with many other topics, MORT describes in detail the design of his clocks, including his masterpiece W5. Woodward contributed dozens of articles to horological periodicals over more than 30 years. From his experience as a mathematician and analyst of complex systems, he has made major contributions to scientific horology, including the definitive analysis of balance springs and much work on the properties of pendulums.

The mechanism was on display in the Ducal Palace in 2001. Articles written by Renato and Franco Zamberlan, and published in the British Horological Journal in 2001, accuse Brusa and Gorla of poor choices, unsound restoration methodology and inappropriate workmanship. The restoration was also criticized by Alberto Peratoner, who was the incumbent temperatore when the post was abolished in 1998. The restorers undid some of the changes made in 1857, changing the pendulum's length and position, for example, although not back to their 1752 condition.

While based in Indiana, students were taught the art of making high grade chronometers and fine lever watches from raw material. Engraving and optician's work, were also taught, and pupils were required to master every detail of the work. After the move to Illinois, the object of the institute was not to make money, but to turn out competent watchmakers and jewelers. The institute gave the student a thorough education in horology, including instructions in making watches, chronometers, clocks and horological machinery in general, as well as repairing the same.

On leaving the army in 1947 with a gratuity of £50, he bought some tools and got a job as a watch repairer. From studying horology at night classes, he became a Fellow of the British Horological Institute. After a decade of hard work, Daniels opened his first watch repair and cleaning shop in 1960 in London. Becoming interested in the works of the notable early 19th-century French watchmaker Abraham-Louis Breguet, he soon became the 1960s' leading expert on Breguet and was often involved in advising on his work.

Just seven years after launching this new line of business, L’Epée submitted its first patents to the authorities to establish and protect its expertise. The Manufacture won recognition throughout the clock making world for its high-quality platform escapements, several of which presented highly specific systems that were very useful at the time, placing the company at the forefront of the horological scene. Some of these patents, such as those protecting the "anti-knocking" system, the "auto-starting" mechanism, and the constant-force escapement, made a lasting impression on their era.

SSIH was created on February 24, 1930 in Geneva by Tissot et Omega, to be joined in 1932 by Lemania Watch Co and A. Lugrin Co in L'Orient (Vallée de Joux). The company specialized in the manufacture of horological complications, enabling Omega to obtain the timing of the 1932 Olympic Games in Los Angeles. This was an important step for the development of Omega's important Sports' Watches segment with exclusive chronographs, such as the Omega Speedmaster. The merger agreement foresaw Omega's concentration on the luxury watch segment, whereas Tissot's mission was to concentrate on the medium price range segment.

The War Office began issuing wristwatches to combatants from 1917. By the end of the war, almost all enlisted men wore a wristwatch, and after they were demobilized the fashion soon caught on: the British Horological Journal wrote in 1917 that "the wristlet watch was little used by the sterner sex before the war, but now is seen on the wrist of nearly every man in uniform and of many men in civilian attire". By 1930 the ratio of wristwatches to pocket watches was 50 to 1. John Harwood invented the first successful self-winding system in 1923.

When Su Song's Xinyi Xiangfayao was written in 1092 and the horological monograph finalized and presented in 1094, his work was published and widely printed in the north (see woodblock printing and movable type of Bi Sheng). In the south, printing and circulation of his work was not widely distributed until Shi Yuanzhi of Jiangsu had it printed there in 1172. When presenting his clocktower design to the Emperor Zhezong, Su Song equated the constant flow of water with the continuous movements of the heavens, the latter of which symbolized the unceasing power of the emperor.Liu, 578, 585.

For example, four o'clock would be sounded as a high tone followed by a low tone, whereas the hour of eleven o'clock would be sounded by two low tones followed by a high tone. The purpose is to conserve the power of the striking train. For example, "VII" would be a total of three strikes instead of seven, and "XII" would be four strikes instead of twelve. Clocks using this type of striking usually represent four o'clock on the dial with an "IV" rather than the more common "IIII",British Horological Institute , Workshop on Roman Numeral Clock Faces, 1999FAQ: Roman IIII vs.

Matthaeus Hahn Philipp Matthäus Hahn (25 November 1739 in Scharnhausen, today part of Ostfildern – 2 May 1790 in Echterdingen, today part of Leinfelden- Echterdingen) was a German pastor, astronomer and inventor. In about 1763 he devised a precision sundial, or heliochronometer that incorporated the correction for the equation of time. In 1774 he designed one of the earliest mechanical calculators of which two are known to have survived to the present day. A renowned clockmaker, several horological museums display his works, including the Deutsches Uhrenmuseum which contains a mechanical orrery (planetarium) and a Weltmaschine by the "Priestermechaniker (priest mechanic)".

In 2015, the Frederique Constant and Alpina brands introduced the "Horological Smartwatch", a smartwatch product with motion and sleep tracking functions that uses a secondary analog dial rather than a screen for its display – giving the timepiece a more classic look than other such devices. The lack of a display screen also provides significant power saving – enabling a battery life of two years or more, in contrast to other smartwatches that must be charged daily. This product line uses "MotionX" core technology, licensed from the California-based company Fullpower Technologies and was developed in a joint venture known as Manufacture Modules Technologies (MMT).

Grindlay was born in Coventry, England in 1876, the fifth child of nine and second son of William Vaughan Grindlay (1843-1891), into a family of established engineers and horological master craftsmen. Upon leaving school, Grindlay joined a local cycle firm and began learning the skills he would employ later in his career. At the age of 20, Grindlay married Emma Chaplin in St Paul's Church, Coventry on the 7th of September 1896, starting his family in 1899 when the first of his two sons was born. By 1901, Grindlay was working at Riley Cycle Company, one of the major firms in Coventry at that time.

The idea being born, Parsons at once determined to establish a horological school and as a result, in 1886, the first school for watchmakers in America was opened in La Porte. The school steadily grew and in 1888, new rooms were provided, affording ample accommodations for 100 students and making possible the pursuit of a greater number of lines of work. The development of the institute was so rapid as to render it difficult for the founder to keep pace with the requirements. After the success of the school had been assured, several offers of considerable sums of money were made to remove the school to other places.

According to a review by H. M. Frodsham of the movement in 1878, H4's escapement had "a good deal of "set" and not so much recoil, and as a result the impulse came very near to a double chronometer action.Harrison M. Frodsham, 'Some Materials for a Resume of Remontoires', Horological Journal, Vol. 20 (1877-78), p120-122" The D shaped pallets of Harrison's escapement are both made of diamond, approx 2mm long with the curved side radius of 0.6 mm; a considerable feat of manufacture at the time. For technical reasons the balance was made much larger than in a conventional watch of the period, 2.2.

For obvious reasons, Arnold tried to keep these methods secret; certainly it is recorded that he clearly expressed his concerns about possible plagiarism to Earnshaw, warning him in no uncertain terms not to use his Helical balance spring.Page 15 "An Appeal to the public" Thomas Earnshaw British Horological Institute reprint 1986. . Nevertheless, a year later, in 1783, Earnshaw—through another watchmaker, Thomas Wright—took out a patent that included Earnshaw's pattern of integral compensation balance and spring detent escapement in the multiple specification. However, both of these were undeveloped and compared to Arnold's were of little use, the balance especially having to be redesigned.

Much of the remainder of the land is occupied by agricultural lands, specifically on the fertile plains over the river valleys. These geological structures resulted in a diversified landscape, dotted by parks, lookouts, belvederes, beaches and salient waters, including the Lagoa das Furnas (Lake Furnas) a volcanic crater lake and the manicured gardens of the Terra Nostra Garden (). The Furnas valley is a source of important horological resources, resulting from the active volcanism of the region, with fumaroles, boiling mud, thermal baths and at least one recognized tepid beach (Ribeira Quente). This valley includes 22 classified mineral-rich medicinal waters (the largest center of its kind).

Since his childhood the horologist showed an inclination towards mechanical, beginning his horological career and making fast progress, in particular, under the direction of Mr. Decroze, manufacturer of Saconnex watches, in the suburbs of Geneva (Switzerland). He moved to Paris in 1744 when he was 24 years of age, serving as apprentice to André-Charles Caron (1698–1775), at that time clockmaker to Louis XV. In 1756 he married Caron's daughter and associated with him, under "Caron et Lépine", between 1756 and 1769.Kannan Chandran, in Solitaire.com Watches with a signature Caron et Lépine or equivalent are not known; apparently Lépine was independent to a certain extent.

While at Harry Winston, Inc. Rare Timepieces Büsser realized that he derived his greatest pleasure and satisfaction when developing concept- style watches for the Opus series, which motivated him to create his own brand and focus on creating three-dimensional kinetic art that he calls "Horological Machines". Büsser's goal for MB&F; (for Maximilian Büsser and Friends) is for the company to remain small enough not to require a middle layer of management, which Büsser feels is detrimental to creativity. To that end he has capped the head count at 20 people and sells his timepieces in the hundreds rather than the thousands, although the majority of the brand's watches sell for upwards of $50,000.

Vacheron Constantin is a highly regarded watch manufacturer. Over the years, notable Vacheron Constantin patrons and timepieces owners include Queen Elizabeth II, Alexander I of Yugoslavia, Pope Pius XI, Napoléon Bonaparte, Marlon Brando, William James, John D. Rockefeller, Diana Princess of Wales, Harry S. Truman, and the Wright brothers. The Vacheron Constantin pocket watch No. 402833 (1929), which was owned by King Fuad I of Egypt, ranks as one of the most expensive watches ever sold at auction, fetching US$2.77 million (3,306,250 CHF) in Geneva on April 3, 2005. In 2015, Vacheron Constantin introduced the pocket watch Reference 57260, which currently holds the title of the most complicated mechanical watch ever made, with 57 horological complications.

On the contrary, every improvement and modification of timepieces and every additional form of movement called for higher skill in handling these delicate machines. The idea of a school for watchmakers was first conceived by James R. Parsons (born in Michigan, circa 1847), of La Porte, Indiana. He was himself experienced in watchwork and felt that what he had spent so many of the best years of his life in learning, could be taught in much less time in a horological school. Besides, in his trade, he had found it hard to get the work done in a workmanlike manner and he saw the large and increasing field of labor for skilled workmen.

Around 75 electronic speaking clocks with the Pat Simmons voice were sold.Telecommunications Heritage Group The Speaking Clock machine that was used by Pat Simmons was displayed on an edition of the BBC television programme, Antiques Roadshow, originally broadcast on 19 October 2008. It had been on display as a working machine at the museum of the British Horological Institute. About forty-four minutes into the programme, Alan Midleton, who had made past appearances as a watch and clock expert on the show in previous episodes but was appearing as a curator of the museum, claimed that the electric motor of the machine, which had been running at the institute, broke down on the same day that Pat Simmons died.

Su Song was the engineer for a hydro-mechanical astronomical clock tower in medieval Kaifeng, which employed the use of an early escapement mechanism.Needham, Volume 4, Part 2, 445.Needham, Volume 4, Part 2, 448.Bodde, 140.Fry, 10. The escapement mechanism of Su's clock tower had been invented by Buddhist monk Yi Xing and government official Liang Lingzan in 725 AD to operate a water-powered armillary sphere, although Su's armillary sphere was the first to be provided with a mechanical clock drive.Needham, Volume 3, 351. Su's clock tower also featured the oldest known endless power-transmitting chain drive, called the tian ti (), or "celestial ladder", as depicted in his horological treatise.Needham, Volume 4, Part 2, 111.

Grasshopper escapement, 1820 The grasshopper escapement is a low-friction escapement for pendulum clocks invented by British clockmaker John Harrison around 1722. An escapement, part of every mechanical clock, is the mechanism that gives the clock's pendulum periodic pushes to keep it swinging, and each swing releases the clock's gears to move forward by a fixed amount, thus moving the hands forward at a steady rate. The grasshopper escapement was used in a few regulator clocks built during Harrison's time, and a few others over the years, but has never seen wide use. The term "grasshopper" in this connection, apparently from the kicking action of the pallets, first appears in the Horological Journal in the late 19th century.

The clock face after restoration (2006) St Mark's Clock is housed in the Clock Tower on the Piazza San Marco (Saint Mark's Square) in Venice, Italy, adjoining the Procuratie Vecchie. The first clock housed in the tower was built and installed by Gian Paolo and Gian Carlo Rainieri, father and son, between 1496 and 1499, and was one of a number of large public astronomical clocks erected throughout Europe during the 14th and 15th centuries. The clock has had an eventful horological history, and been the subject of many restorations, some controversial. After restorations in 1551 by Giuseppe Mazzoleni, and in 1615, by Giovanni Battista Santi, the clock mechanism was almost completely replaced in the 1750s, by Bartolomeo Ferracina.

The German Clock Museum in Furtwangen portrays the history of the clock industry and of watchmakers. For drivers, the main route through the region is the fast A 5 (E35) motorway, but a variety of signposted scenic routes such as the Schwarzwaldhochstraße (, Baden-Baden to Freudenstadt), Schwarzwald Tälerstraße (, the Murg and Kinzig valleys) or Badische Weinstraße (Baden Wine Street, , a wine route from Baden- Baden to Weil am Rhein) offers calmer driving along high roads. The last is a picturesque trip starting in the south of the Black Forest going north and includes numerous old wineries and tiny villages. Another, more specialized route is the German Clock Route, a circular route that traces the horological history of the region.

Charles Oudin, the best known member of this horological dynasty, established his business toward the end of the 18th century, devoting himself to luxury and precision clocks and watches. The first watches signed "Charles Oudin, éléve de Breguet" (Charles Oudin, student of Breguet) date from 1797. In 1805 he made a repeating à tact watch for Empress Josephine[1]. Taking part in the important exhibitions of the period, he attracted notice; at the Exhibition of the products of French Industry in 1806, he received an Honourable Mention for a self-winding watch [2]; at the 1819 Exhibition of the products of French Industry, he received a Citation for an equation watch [3].

Robert Greubel (left) and Stephen Forsey Robert Greubel grew up in Alsace, France and began his horological career by working with his watchmaker father in the family shop, Greubel Horlogerie. In 1987 Greubel moved to Switzerland to join the International Watch Company (IWC), where he helped develop their Grand Complication. In 1990 he joined Renaud & Papi SA (now Audemars Piguet Renaud & Papi SA) as a prototypist for complicated movements and rose to become managing director and partner. Stephen Forsey grew up in St Albans, England, where he was inspired by his father's passion for mechanics and engineering. From 1987 to 1992 Forsey specialized in antique clock restoration and became head of Watch Restoration at Asprey’s in London.

A keen amateur horologist, Lord Tanlaw is a Fellow of both the Royal Astronomical Society and the British Horological Institute. In 2005, he introduced the Lighter Evenings (Experiment) Bill, which would move the United Kingdom's time zone forward by one hour, to UTC+1 in the winter and UTC+2 in the summer, for a trial period of three years. Lord Tanlaw claims that this would reduce accidents in the winter as the evenings would be lighter, and has the backing of the Royal Society for the Prevention of Accidents. Opponents fear that it would have an adverse effect on people living in Scotland and northern England, where the mornings would be much darker.

Bradley decided instead to found a school where young people could learn how to do practical things to prepare them for living in the modern world. As a first step toward her goal, in 1892 she purchased a controlling interest in Parsons Horological School in LaPorte, Indiana, the first school for watchmakers in America, and moved it to Peoria. She specified in her will that the school should be expanded after her death to include a classical education as well as industrial arts and home economics: "...it being the first object of this Institution to furnish its students with the means of living an independent, industrious and useful life by the aid of a practical knowledge of the useful arts and sciences." In October 1896 Mrs.

The most advanced techniques in horological engineering produced a truly one-of-a-kind timepiece; only one watch was ever built. Complications included a perpetual calendar with phases and age of the moon, indication of sunrise and sunset, and a celestial chart depicting the stars in the nighttime sky over New York City.- Graves died in 1953. His heirs sold the watch in 1968 to The Time Museum in Rockford, Illinois, which closed in March 1999. (From January 2001 through February 2004 the Time Museum collection was displayed at Chicago's Museum of Science and Industry, then sold.) The watch was held in the Rockford Time Museum until it was sold at Sotheby's for a record breaking $11,002,500 to an anonymous bidder in New York City on December 2, 1999.

The 18th- and 19th-century wave of horological innovation that followed the invention of the pendulum brought many improvements to pendulum clocks. The deadbeat escapement invented in 1675 by Richard Towneley and popularised by George Graham around 1715 in his precision "regulator" clocks gradually replaced the anchor escapement and is now used in most modern pendulum clocks. The observation that pendulum clocks slowed down in summer brought the realisation that thermal expansion and contraction of the pendulum rod with changes in temperature was a source of error. This was solved by the invention of temperature-compensated pendulums; the mercury pendulum by George Graham in 1721 and the gridiron pendulum by John Harrison in 1726. With these improvements, by the mid-18th century precision pendulum clocks achieved accuracies of a few seconds per week.

Monument of Antoine LeCoultre The earliest records of the LeCoultre family in Switzerland date from the 16th century, when Pierre LeCoultre (circa 1530 – circa 1600), a French Huguenot, fled to Geneva from Lisy-sur-Ourcq, France to escape religious persecution. In 1558, he obtained the status of “inhabitant” but left the following year to acquire a plot of land in the Vallée de Joux. Over time, a small community formed and in 1612, Pierre LeCoultre's son built a church there, marking the founding of the village of Le Sentier where the company's Manufacture is still based today. In 1833, following his invention of a machine to cut watch pinions from steel, Antoine LeCoultre (1803-1881) founded a small watchmaking workshop in Le Sentier, where he honed his horological skills to create high-quality timepieces.

Aqua Horological Tintinnabulator, the Victoria Centre, Nottingham An otherwise undistinguished career was interrupted by World War II, when he worked as a draughtsman for the Air Ministry while perfecting his gift for drawing cartoons. From 1939 until the 1950s, and less frequently in the 1960s, he published regularly in PunchThe Emett Catalogue (in preparation) and for many years when his work was published elsewhere it was credited to "Emett of Punch". His cartoons were seldom political, except when he caricatured bureaucratic absurdities, and his early subjects typically found humour in the difficulties of life in Great Britain during the second World War. His drawings soon started to include railway scenes and he gradually developed a unique concept of strange, bumbling trains with excessively tall chimneys and silly names.

His magnificent Second Sculptural Clock, made in 1965, is now owned by the American graphic artist Donald Saff. The clock (which appeared on the cover of the Horological Journal for August 2001) has a massive compound pendulum which beats at 2.5 seconds and an escape wheel which turns in five minutes. A limited edition of thirty-five half-size replicas, known as ‘'Concord clocks'’, Harrison style with grasshopper escapement and compound pendulum, was made by E. Dent and has the dimensions high, wide, deep. Burgess's Third Sculptural Clock, generally known as the Hares and Tortoises clock, was the most ambitious to date, and was his first speculative venture. It draws influences from Jost Bürgi, Edmund Beckett, 1st Baron Grimthorpe and John Harrison. It is 35 inches (880 mm) tall and 37 in (950 mm) wide.

When in 2000, the Woodward Building was opened by Sir John Chisholm at the Defence Evaluation and Research Agency (DERA), now privatized as QinetiQ, guests were given complimentary clocks as souvenirs of the occasion and of Woodward's horological interests. In June 2005, the Royal Academy of Engineering gave Woodward its first Lifetime Achievement Award, recognizing him as an outstanding pioneer of Radar and for his work in precision mechanical horology. In 2009 he received the Institute of Electrical and Electronics Engineers (IEEE), Dennis J. Picard Medal for Radar Technologies and Applications: "for pioneering work of fundamental importance in radar waveform design, including the Woodward ambiguity function, the standard tool for waveform and matched filter analysis".

In addition to the first three Eco-Drive models introduced in 1995, Citizen marketed numerous other Eco-Drive models during the 1990s, including the thick Eco-Drive Slim of 1996. Where the first models offered hours, minutes, seconds and date features, ultimately the movements evolved to include a broad range of design features, including complex analog and digital-analog movements and the horological complications of chronographs, flyback chronographs and dive watches. In the early 2000s, while wristwatch sales declined with the advent of cell phones and their timekeeping capability, demand for Citizen watches in North America remained robust. Eco- Drive models were well received, generating a third of Citizen's North American revenues by 2000. In 2002 the VITRO technology (Eco-Drive VITRO) came on the market, where the solar cells were no longer even slightly visible under the dial.

Tourists flock to the Observatory museum, 2009 The observatory buildings at Greenwich became a museum of astronomical and navigational tools, which is part of the Royal Museums Greenwich. Notable exhibits include John Harrison's sea watch, the H4, which received a large reward from the Board of Longitude, and his three earlier marine timekeepers; all four are the property of the Ministry of Defence. Many additional horological artefacts are displayed, documenting the history of precision timekeeping for navigational and astronomical purposes, including the mid-20th-century Russian-made F.M. Fedchenko clock (the most accurate pendulum clock ever built in multiple copies). It also houses the astronomical instruments used to make meridian observations and the 28-inch equatorial Grubb refracting telescope of 1893, the largest of its kind in the UK. The Shepherd Clock outside the observatory gate is an early example of an electric slave clock.

Boston Clock Company continued to produce clocks like they did when they were Harvard Clock Company. However, in 1886, they began producing striking clocks after the invention of the Boston tandem wind movement. They also began to produce ship’s bell clocks, although they were limited and appear to be prototypes. Circumstantial evidence shows these ship’s bell marked with “Boston Clock Co.” were assembled at the Vermont Clock Company circa 1900. Boston Clock Company produced approximately 150,000 clocks between 1884-1894. On January 31, 1894, the Jewelers’ Circular of Horological Review reported that the Ansonia Clock Company bought out the Boston Clock Company. On September 4, 1895, The Circular reported that the Boston Clock Company was transferred to Charles O. Warner on private terms. According to the report, the estate consisted of a large brick building and lots of land containing about 50,362 square feet, appraised for $5,000. The whole was assessed for $35,000. The Ansonia Clock Company continued to offer Boston Clock Company clocks in their catalogue until late 1907.

Louis Achille Brocot (pronounced "broco"Phonetic blunder) (11 July 1817 – 19 January 1878) was a French clockmaker. and amateur mathematician.. He is known for his discovery (contemporaneously with, but independently of, German number theorist Moritz Stern) of the Stern–Brocot tree, a mathematical structure useful in approximating real numbers by rational numbers; this sort of approximation is an important part of the design of gear ratios for clocks.. Several improvements in clock design was attributed to Brocot. He invented the "Brocot Suspension", which enabled time keeping to be regulated by altering the length of the pendulum suspension spring by a key turned in the dial. He also made many practical horological innovations including refinement of his father Louis-Gabriel's Brocot escapement and the development of clocks with perpetual calendar mechanisms.. Powerpoint presentation based on .. In order to commercially exploit his original designs, together with Jean-Baptiste Delettrez he established the clockmaking company "Brocot & Delettrez" in Paris on 20 October 1851, a partnership that would continue until his death.

They supplied both the Turkish railroad system and the Italian railroad system, as well as a number of street car systems throughout Europe. In the 1927, at the request of Mussolini, Cortébert started distributing their watches in Italy under the Perseo brand name. It is under this name that they were used by the Italian railway system. Cortebert distributed their Italian railroad watches through the Perseo brand as the fascist Italy rejected foreign brand names. In the early 1920s, Cortébert was approached by Soviet Russia for assistance in establishing a watch industry in Russia. Russia purchased machinery and technical advice from Cortébert, and manufactured the Cortébert 616 pocket watch movement in Russia as the "Molnija". Production of this movement continued in Russia until early 2014 when production ceased. According to Jose Pereztroika, the famous horological forensics expert, there is no evidence for this claim. In addition, the Molnija 3201 is not based on Cal. 616 but on Cal. 620 which is considerably thinner. A closer inspection of Molnija 3201 movements shows heavy discrepancies compared to Cortebert 620 calibers, which is an indication that the Russian movements were not made with Swiss machines or tools.

It is undocumented where he learned his clockmaking skills, but eventually he became the most innovative clock and scientific instrument maker of his time.Jost Bürgi als Künstler der Mechanik, Separatum Toggenburgerblätter für Heimatkunde 1982/Heft 34; by Johann Wenzel; Publisher: ToggenburgerblaetterJost Burgi 1552-1632, Horloger, Astronome & Mathematicien; by M.L. Defossez; Publisher: SSC, separate offprint of a 20 page biographic article on Jost Bürgi, first published in the 1943 Annual Bulletin of the Societe Suisse de Chronometrie Among his major horological inventions were the cross-beat escapement, and the remontoire, two mechanisms which improved the accuracy of mechanical clocks of the time by orders of magnitude. This allowed for the first time clocks to be used as scientific instruments, with enough accuracy to time the passing of stars (and other heavenly bodies) in the crosshairs of telescopes to start accurately charting stellar positions.

The Clockmakers Company first established a library collection in 1814, under the control of a library committee, in which Benjamin Lewis Vulliamy soon emerged as the most prominent figure, remaining so for several decades. Early meetings were held at Vulliamy's premises in Pall Mall, London but in 1817 the Company acquired a mahogany bureau and bookcase from Gillows of Lancaster and London, to house its growing collection, and this was established in an upper room in the Kings Head Tavern in Poultry, London, where the Company had its meetings from 1802 to 1851. From 1815, the collection had expanded from books to include horological exhibits, among which an early acquisition was a set of pallets from an escapement by Alexander Cumming, bought by Vulliamy at auction, and which are still on display, on the Gillows bookcase. With the deaths of BL Vulliamy and George Atkins, Clerk to the Company, in the 1850s, the collection lost its key advocates and supporters, but the fortunes of the museum were reversed with the construction of a new building for Guildhall Library in the early 1870s. At the invitation of the Guildhall authorities, the Clockmakers’ Museum was moved there and opened to the public from 1873.
