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

Verge and pair-cased watches

After Christiaan Huygens and Robert Hooke applied the balance spring around 1675, the verge watch became a reasonably reliable timekeeper and the minute hand became standard. Through the eighteenth century the typical English watch was a pair-cased verge: a fusee movement with a pierced, engraved balance cock, housed in an inner case and a separate protective outer case, often of repoussé gold, shagreen, tortoiseshell or enamel.

French watches of the same period were thicker 'oignons', later replaced by elegant thinner watches following Jean-Antoine Lépine's bar-bridge calibre of c. 1770. Dutch, Swiss and German makers supplied international markets, and verge watches were made until the mid-nineteenth century as cheaper alternatives to the cylinder and lever.

What to look for

  • The pierced balance cock on the backplate: winged (continental) or with a foot (English); its style dates the watch.
  • Fusee and chain visible through the movement; key winding through the dial (early) or case back.
  • Hallmarks inside English silver or gold cases, which give a date letter.
  • Maker's name and serial number engraved on the backplate; watch papers inside outer cases.
  • Enamel dials (after c. 1720) versus earlier champlevé metal dials.

Dating clues

  • Champlevé dials: c. 1680–1730; white enamel dials thereafter.
  • English case hallmarks give the year of assay to within a year.
  • Verge watches persisted in cheap production until c. 1850.
