Historical context

Golden Age of Mechanical Watchmaking (1900 – 1945)

The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.

The pocket watch reached technical maturity and then began to give way to the wristwatch after the First World War. Complicated watches for collectors such as Henry Graves Jr. and James Ward Packard, railroad watches, and slim Art Deco dress watches are characteristic.

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.
