Daniel Quare

Daniel Quare was a London clock- and watchmaker, and a prominent Quaker tradesman, admitted to the Clockmakers' Company and later serving as its Master. He is traditionally credited, alongside the rival claim of Edward Barlow, with inventing the repeating watch mechanism in the early 1680s, whereby a watch could sound the approximate time on demand by pulling a cord or pressing a pendant, useful for telling time in darkness before pocket lighting was practical.

The Quare–Barlow priority dispute over the repeater is one of the recorded controversies of English horology: Barlow is generally understood to have petitioned for a patent first, but Quare's mechanism was preferred by King James II's court and Quare received royal favour for it, so the historical record credits both men rather than settling sole priority, and this entry follows that standard treatment rather than assigning invention to Quare alone.

Quare also built turret clocks, and equation clocks showing the difference between solar and mean time, and was noted for barometers as well as clocks; his religious nonconformity as a Quaker occasionally brought him into conflict with oath-based guild and civic requirements, a detail recorded in Company records of the period.
