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

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.
