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

Repeating watches

Before electric light, telling the time in the dark was a real problem. Repeating watches strike the time on demand when a slide or push-piece is operated: quarter repeaters sound hours and quarters, minute repeaters hours, quarters and minutes. Edward Barlow and Daniel Quare disputed the invention in London in the 1680s. Early repeaters struck on a bell inside the case; Abraham-Louis Breguet introduced the gong (a coiled steel wire) around 1780, allowing thinner watches.

Repeaters require a separate train with racks, snails and a governor to control the striking speed, and are among the most demanding complications to make and adjust. Swiss makers of the Vallée de Joux specialised in repeating ébauches in the nineteenth century.

What to look for

A slide on the case band or a push-piece through the pendant.
Gongs encircling the movement (after c. 1780) or a bell in the case (earlier); pierced case for sound.
The racks, snails and governor visible under the dial or on the movement.
Terms such as 'Minutes', 'Quarts' or 'Répétition' on the dial or cuvette.

Dating clues

Bell-striking quarter repeaters: c. 1690–1800.
Gong repeaters and dumb repeaters (striking on the case): after c. 1780.
Minute repeaters became more common after c. 1830 with Vallée de Joux ébauches.
