Historical context
Modern Mechanical Horology (1945 – 1969)
Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
After 1945 the pocket watch became a niche product — presentation and railway watches, inexpensive pin-lever watches, and commemorative pieces — while most innovation moved to the wrist.

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.
