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.
