Catalogue description

Science Museum Group description

Although this watch has only a single hand which points to the minute markers, it is able to also read the hours thanks to the clever system it employs. The minute hand rotates clockwise once per hour, as standard. The central hour disc also rotates in the same direction, but at 11/12 the speed of the minute hand. This enables the correct portion of the hour to be read as it 'keeps up' with the rotating hand. Clockmakers' Museum No. 1195

Historical context

Early Modern Horology (1600 – 1750)

Huygens' pendulum and balance spring transform accuracy; English makers develop the anchor and deadbeat escapements.

The balance spring (c. 1675) improved watches dramatically and introduced the minute hand. English pair-cased verge watches with pierced balance cocks and French oignons were typical; enamel painting at Blois and Geneva, and the repeating watch (1680s), made watches objects of great refinement.

Atlas type guide

Pocket watches

The pocket watch was the dominant personal timekeeper from the late seventeenth century until the First World War. Its development tracks the history of the escapement: verge watches with fusees until the late eighteenth century; Thomas Mudge's lever escapement (c. 1755) and the cylinder escapement popularised by George Graham and later by Swiss makers; and the Swiss and English lever watches of the nineteenth century. Lépine's bar-bridge calibre and keyless winding made watches thinner and easier to use.

Industrialisation transformed the trade: American factories such as Waltham (from 1850) and Elgin produced interchangeable parts by machine, and Swiss makers responded with their own mechanisation after the 1876 Philadelphia Exhibition. By 1900 a reliable watch was affordable to millions; the finest makers continued to produce complications and precision watches.

What to look for

  • The escapement: verge (crown wheel), cylinder, duplex, English or Swiss lever.
  • Key winding (a square arbor in dial or back) or keyless crown winding.
  • Signatures and serial numbers on the movement, dial and inside case back.
  • Hallmarks, case maker's marks and gold or silver standards stamped in the case.
  • Dial material: enamel, silver, gold, later printed metal.

Dating clues

  • Verge watches dominate before c. 1800; cylinder watches c. 1770–1900; lever watches after c. 1820.
  • Keyless winding: increasingly common after c. 1860.
  • Manufacturer serial number lists exist for Waltham, Elgin, Longines, Omega, Patek Philippe and others.
