Historical context

Precision & Scientific Horology (1750 – 1850)

Harrison solves longitude; Mudge invents the lever; Breguet's Paris workshop defines the modern watch.

From 1750 to 1850 the watch became a precision instrument. Mudge's lever escapement, the cylinder escapement, Lépine's thin bar calibre, Breguet's innovations (overcoil, tourbillon, perpétuelle) and the pocket chronometer of Arnold and Earnshaw all date from this period, while verge watches remained common in cheaper production.

Atlas type guide

Hunter, half-hunter and open-face watches

In the nineteenth century the pocket watch case settled into a few standard forms. The hunter (French savonnette) has a hinged front lid protecting the crystal — reputedly for riders who could not risk broken glass — and is opened by pressing the crown or a push-piece. The half-hunter has a small window in the lid so the hands can be read when closed. The open-face (lépine) watch has no front cover, with the crown at 12; hunters normally carry the crown at 3.

Case types also changed with winding: key-wound watches gave way to keyless (stem-wound) mechanisms after Adrien Philippe's and others' designs of the 1840s, with pendant setting or lever setting.

What to look for

  • Crown position relative to the seconds dial: at 3 for hunters, at 12 for open-face watches.
  • Spring-loaded front cover with a push-piece in the pendant.
  • Half-hunter chapter ring enamelled on the lid.
  • Key holes in the inner dome (cuvette) versus keyless winding.

Dating clues

  • Keyless winding spread after c. 1850 and became standard by c. 1890.
  • English hallmarks inside gold and silver cases give the year of assay.
