Historic watches & clocks
England · Completed 1735Harrison H1John Harrison's first sea clock, built to compete for the longitude prize established by the Board of Longitude's 1714 act.John Harrison
England · Completed 1759; sea trial 1761–1762Harrison H4A radical departure from Harrison's earlier sea clocks: a large silver pocket-watch-sized instrument rather than a pendulum-like machine.John Harrison
England · Traditionally dated to c. 1386, though the surviving documentary basis for this exact date is debated among scholarsSalisbury Cathedral ClockFrequently cited as one of the oldest working clock mechanisms in the world still substantially in its original form, though 'oldest' claims of this kind are always comparative and depend on how much of the mechanism is original fabric versus later restoration.Unknown (attributed to an unnamed English or French clocksmith of the workshop tradition)
Czech Republic (Bohemia) · First mechanism 1410; astronomical dial and later apostle figures added and rebuilt across subsequent centuriesPrague Astronomical Clock (Orloj)One of the oldest astronomical clocks in the world still operating, showing the position of the sun and moon against the zodiac in addition to time.Attributed traditionally to Mikuláš of Kadaň and later astronomical dial work to Jan Šindel; mechanically overhauled several times since
France (Strasbourg Cathedral) · Current mechanism completed 1842, replacing two earlier astronomical clocks on the same site (first c. 1354, second c. 1574)Strasbourg Astronomical ClockThe present clock is the third built at Strasbourg Cathedral; Schwilgué incorporated a mechanical computer capable of calculating moveable feasts (including Easter) and functioning correctly through the Gregorian calendar's leap-year exceptions.Third (current) clock built by Jean-Baptiste Schwilgué
France · Commissioned 1783; completed 1827, four years after Breguet's own death in 1823Breguet No. 160 'Marie-Antoinette'Reportedly commissioned by an admirer of Marie-Antoinette with instructions to use gold wherever possible and to include every complication then known, though the details and even the identity of the commissioner are recorded through secondary Breguet-company tradition rather than a surviving original commission letter, and should be treated with appropriate caution.Breguet (completed by Breguet's successors after his death)
Switzerland · Commissioned 1925; delivered 1933Patek Philippe Graves SupercomplicationCommissioned by American banker Henry Graves Jr., reportedly in a competition of horological one-upmanship with fellow collector James Ward Packard; the rivalry narrative is widely repeated in auction-house and company materials and is treated here as documented commercial history rather than independently re-verified primary correspondence.Patek Philippe
United States · Vanguard grade introduced late 19th century, produced into the 20th centuryWaltham Railroad-Grade Movements (Vanguard and related grades)Representative rather than a single unique object: the Vanguard and comparable Waltham railroad grades illustrate American industrial precision watchmaking built to meet railway time-service standards.American Waltham Watch Company
Switzerland (manufacture); China (market) · Principally 19th centuryChinese-Market Duplex Watches (Swiss export production)A distinct category rather than a single object: Swiss (and some English) firms produced heavily decorated, often enamel-cased duplex-escapement watches specifically for export and sale in China, a trade that shaped decorative styles and movement choices for decades.Various Swiss export houses (e.g. firms trading through Bovet and other Swiss/Chinese-market specialists)
England · Late 18th centuryJohn Arnold Marine Chronometers (representative series)Arnold's chronometers, alongside Earnshaw's, established the spring-detent escapement and bimetallic compensation balance as the practical basis of marine timekeeping.John Arnold & Son
England · c. 1690 (British Museum catalogue text; a museum exhibition note links it to the coronation of William III and Mary II in 1689)Tompion 'Mostyn' ClockA year-going spring clock: the British Museum's catalogue text (David Thompson) notes that English spring-driven clocks of such long duration did not exist before it, calls Tompion the first in England to meet the challenge and the clock the pinnacle of his achievement as a practical clockmaker.Thomas Tompion
England · Movement completed 1854; clock began operating 1859The Great Clock of Westminster ('Big Ben', properly the bell)'Big Ben' properly refers to the Great Bell; the phrase is very widely used for the whole clock and tower, and this popular usage should be flagged rather than silently repeated as the technically correct name.Movement by Edward John Dent, to a design by Edmund Beckett Denison (later Lord Grimthorpe)
England · Patented 1808Congreve Rolling-Ball Clock (type)An unusual escapement type in which a ball rolls along a grooved, tilting plate; when the ball reaches one end, the plate tilts the other way (driven by the clock's going train) and the ball rolls back, each traverse taking a set time.Sir William Congreve (design); various English and later manufacturers producing the type
Switzerland · Reutter's mechanism developed from the 1920s; Jaeger-LeCoultre began manufacture in 1936 (Atmos I onward)Jaeger-LeCoultre Atmos ClockMarketed as needing no manual winding: small changes in the temperature of a sealed gas capsule expand and contract a bellows that rewinds the mainspring, in principle allowing the clock to run indefinitely from ambient conditions.Jaeger-LeCoultre, based on Jean-Léon Reutter's mechanism
England · Introduced 1921–1922Shortt-Synchronome Free Pendulum ClockRegarded as the most accurate mechanical/electromechanical pendulum clock system ever put into regular service, used as a time standard by observatories including Greenwich before quartz clocks superseded it.William Hamilton Shortt and the Synchronome Company (Frank Hope-Jones)
Switzerland · Speedmaster introduced 1957; NASA-qualified 1965 following documented testingOmega Speedmaster (NASA-qualified, worn on Apollo missions)Qualified by NASA in 1965 after documented environmental testing for use on manned spaceflights, and worn during Gemini and Apollo missions, including on the surface of the Moon.Omega
Switzerland · 1953 and 1960 test descentsRolex Deep Sea Special (Trieste bathyscaphe test pieces)Experimental prototypes, not a production model, attached externally to the bathyscaphe Trieste for record-depth descents, including the 1960 Challenger Deep dive with Jacques Piccard and Don Walsh.Rolex
United States · Standard specification established following the 1893 General Railroad Timepiece Standards; production through the early 20th centuryBall Official Railroad Standard Watches (representative series)Webb C. Ball established time-service inspection systems for American railroads following the 1891 Kipton, Ohio train collision attributed partly to a stopped watch, and the Ball name became closely associated with the resulting railroad-grade specification rather than being itself a manufacturer of movements.Ball Watch Company (retailer/inspector specification; movements supplied by Hamilton, Hampden, Waltham and others)
United States · Mid-19th century; famously inscribed inside during Lincoln's presidencyAbraham Lincoln's Personal Pocket WatchHeld by the Smithsonian National Museum of American History, the watch became widely reported in 2009 for a hidden inscription found inside the movement, reportedly added by a watch repairer in 1861 referencing the outbreak of the Civil War.Movement by an American manufacturer of the period (specific attribution should be verified against the holding institution's own catalogue record before citing)
Various manufacture; event associated with the North Atlantic · 1912 sinking; individual watches otherwise dated to their own manufacture, typically late 19th–early 20th centuryRMS Titanic-Associated Pocket Watches (recovered/documented examples)A category rather than a single object: several watches with documented Titanic association (including examples recovered by salvage operations and family-held pieces with documented provenance) have been exhibited and auctioned, each requiring individual provenance verification.Various — attribution must be established per individual watch
Germany · Observatory-trial-submitted movements documented chiefly from the late 19th century through the mid-20th centuryGlashütte Observatory Trial Chronometer MovementsGlashütte's manufacturers, alongside Swiss and other European makers, submitted movements to observatory precision trials (a formal published-rating competition among manufacturers, comparable in purpose to the Swiss trials at Neuchâtel and Geneva), and results are a documented, comparable historical record rather than a marketing claim.Various Glashütte manufacturers (including the historical A. Lange & Söhne and, in the 20th century, VEB Glashütter Uhrenbetriebe)
United States · Introduced 1896Ingersoll 'Yankee' Dollar WatchMarketed at one US dollar, the Yankee watch became an emblem of mass-market affordability, reportedly selling in very large numbers over its production life and popularised further by celebrity endorsement claims in period advertising that should be treated as period marketing rather than independently verified fact.Robert H. Ingersoll & Bro.
England · Astronomical dial traditionally dated to the late 14th century; the original mechanism (now removed from the dial) is held separately, with a later movement now driving the cathedral's dialWells Cathedral ClockOne of the oldest surviving astronomical clock dials in England, showing a geocentric (pre-Copernican) display of the sun and moon appropriate to its period of construction.Attributed traditionally to monk-clockmakers of the period; mechanism now displayed separately from a later replacement movement driving the visible dial
United States · Produced from the mid-19th century onwardE. Howard & Co. Astronomical Regulator ClocksRepresentative of American high-grade precision regulator production used by observatories, railroads and watch-inspection bureaus needing an accurate time reference against which pocket watches could be checked.E. Howard & Co.
United States · Produced from the late 19th century into the 20th centurySeth Thomas Regulator No. 2A widely produced American precision wall regulator commonly used in period offices, railroad stations and schools as a visible accurate time reference; its long production run and broad presence make individual dating and specification confirmation essential rather than assuming a single fixed specification across the whole run.Seth Thomas Clock Company
United States · 1900–1908 (Pocket Watch Database production years)Rockford Watch Company Grade 545 MovementGrade 545 was one of Rockford's 16-size, 21-jewel railroad grades: the Pocket Watch Database records it as a nickel Model 5 open-face movement adjusted to five positions, isochronism and temperature, advertised for railroad service and fitted at the factory with a double-sunk dial.Rockford Watch Company, Rockford, IllinoisUnited States · 1908 (single production run); advertised from 1909South Bend Watch Company 'Polaris' GradeThe Polaris was South Bend's top grade, sold only complete in a South Bend gold case with a 'Polaris' signed dial; about 500 were made in a single run in 1908.South Bend Watch Company, South Bend, Indiana
United States · Late 19th–early 20th centuryHampden 'Special Railway' Grade MovementsHampden's premium railroad-oriented grades illustrate the competitive American railroad-watch market of the period; the company's movements were also used by some watches sold under other retailer names, so movement signatures should be checked directly rather than assumed from case markings.Hampden Watch Company (later Dueber-Hampden)
England · Worked on 1740–1759Harrison H3Harrison's third sea clock, on which he worked for nearly two decades, introducing the bimetallic strip (a direct ancestor of the bimetallic compensation balance used in later chronometers) and caged roller bearings to reduce friction.John HarrisonEngland · c. 1720s–1740sGeorge Graham's Astronomical Regulator ClocksGraham is credited with perfecting the deadbeat escapement (building on earlier work associated with Richard Towneley and Thomas Tompion, whose workshop Graham inherited) and with introducing a mercury-compensated pendulum to counteract thermal expansion.George Graham
Germany · Knife-edge suspension mechanism developed and patented from the late 1880s–1890s; production continued into the 20th centuryRiefler Precision Regulator ClocksSigmund Riefler's knife-edge pendulum suspension, in which the pendulum swings on a rigid spring-steel blade bearing rather than a conventional flexible spring suspension, greatly reduced suspension-related timing errors and made Riefler regulators the leading observatory time standard of their era, before being superseded by the Shortt-Synchronome system and later quartz clocks.Clemens Riefler / Sigmund Riefler workshop, Munich
France · Commissioned 1897 by Antonio Augusto de Carvalho Monteiro; completed 1904Leroy 01Commissioned by the Portuguese collector Antonio Augusto de Carvalho Monteiro with instructions to combine everything then achievable in watchmaking science and mechanics, the Leroy 01 held a long-standing reputation, repeated in specialist literature, as the most complicated watch in the world for roughly eight decades after its completion.

Italy (original); reconstructions built in Italy and England · Original completed 1364 (no longer survives); reconstruction by Luigi Pippa built 1961–1963 based on Dondi's manuscript; a separate reconstruction project undertaken in England 1961–1974Dondi Astrarium (modern reconstruction)Giovanni Dondi's original astrarium, completed after sixteen years' work in 1364, displayed the time, calendar and the positions of the sun, moon and five known planets on seven separate dials driven from a single weight, using around 107 moving parts, and was regarded by contemporaries as an extraordinary technical achievement; the original itself does not survive, with its last documented sighting recorded in 1529. [2](https://www.cabinet.ox.ac.uk/giovanni-dondis-astrarium-1364)Original design by Giovanni Dondi dall'Orologio; modern reconstructions built from Dondi's own treatise
Japan · Principally 17th to mid-19th century, ending with the adoption of the Western-style 24-hour day following the Meiji-era calendar reform of 1873Wadokei (Japanese Edo-Period Lantern Clocks)Wadokei were built on imported and later domestically made European verge-and-foliot clock movements but were adapted to Japan's traditional system of dividing daylight and night each into six 'hours' of unequal length that varied through the year, a fundamentally different requirement from the fixed-length hours of European clocks.Various Japanese clockmakers of the Edo period
England · Late 18th centuryThomas Earnshaw Marine Chronometers (representative series)Earnshaw developed a simplified, more easily manufactured spring-detent escapement and bimetallic compensation balance, and his designs proved decisive in making marine chronometers producible in meaningful numbers rather than as individual bespoke instruments.Thomas Earnshaw
France · Developed from the early 1790s through the early 19th centuryBreguet Pendule Sympathique (clock-and-watch pair)Breguet devised a system in which a specially made pocket watch is placed into a cradle atop a companion mantel clock overnight; the clock mechanism engages the watch to correct its time to match the clock and, in some versions, to wind it, a highly sophisticated mechanical solution to the everyday problem of keeping a portable watch accurately set.Abraham-Louis Breguet

Isfahan, Iran · 1715 (museum dating)Isfahan planispheric astrolabe, Saint Louis 41:1926The Saint Louis Art Museum identifies this brass instrument as Persian, made in Isfahan in 1715 during the Safavid dynasty. Its record separates Mohammad Amin ibn Mohammad Taher as maker from Abd al-A'immah as decorator. Those roles must remain distinct even though the museum notes that the two instrument makers worked both together and separately.Mohammad Amin ibn Mohammad Taher (maker); Abd al-A'immah (decorator)
Isfahan, Iran · ca. 1715Abd al-A'imma astrolabe, Oxford inventory 37321Oxford's historical astrolabe catalogue attributes inventory 37321 to ‘Abd al-A’imma, gives Isfahan as its place and dates it approximately to 1715. It transcribes the signature on the back as ‘Made by ʿAbd al-Aʾimmah’. This is a different object from Saint Louis 41:1926, whose record assigns that name to the decoration rather than manufacture.‘Abd al-A’imma (Oxford catalogue attribution)

Its place field says Persia, not a particular city. A name associated with Yazd or the prominence of Isfahan workshops is not sufficient evidence to assign this object to either city.Muḥammad Muqīm al-Yazdī (catalogue maker); Faṣl Allah al-Sabzawārī named in a back inscription

France (case); The Hague (movement) · Case 1640–1660; movement 1740–1760 (date field)Painted-enamel watch with Mars, Venus and CupidThis gold case is painted with figures the museum reasonably identifies as Mars, Venus and Cupid; the qualification matters because iconographic interpretation is not an inscription naming the subject. Landscape vignettes continue around the sides and inside the case. The dial combines a painted centre with a white enamel chapter ring.Case artist unknown; later movement by Jan Bernardus Vrythoff
France, Paris · 1640–1650Nicolas Bernard watch with Faith, Hope and CharityThe V&A names Nicolas Bernard as watchmaker and identifies a gold case painted with Charity on the front and Faith and Hope on the back. Landscapes decorate the dial, sides and interior surfaces. Its summary connects the case to improved miniature painting in enamel around 1630, while naming Jean Toutin among the key figures in that development; this is not an attribution of this particular case to Toutin.Nicolas Bernard, watchmaker; case painter not identified

A signature and a plausible date do not remove that qualified identity.Robert Grinkin; probably the elder, as museum interpretation
Probably Turkey; movement origin uncertain · ca. 1670Calendar watch with Arabic inscriptions, 136-1907This engraved gilt-brass and silver watch has separate calendar and hour indications, with apertures for lunar phases, days of the week and months.

The museum dates the enamelled exterior to 1650–1670 and the movement to 1750–1775. Its silver chapter ring, blued steel hand and engraved dial belong to the preserved assembled object; they should not all be assigned the exterior’s seventeenth-century date.Case artist unknown; movement signed Samuel François Caille, Vienna
