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.
