(Antoine) Jean-Baptiste Delettrez (1 May 1816 - 25 May 1887) was a well-known 19th century French watchmaker .
Delettrez and Achille Brocot, son of the respected watchmaker Louis-Gabriel Brocot, founded the watchmaking firm 'Brocot & Delettrez' in Paris on 20 October 1851, based at 62 Rue Charlot. Delettrez collaborated with Achille Brocot for several years and their clock mechanisms are considered the most successful made at the end of the 19th century. Their speciality was a range of clocks based on the innovations of Brocot père and his second son Antoine, but generally very advanced of Achille's original design, some with a unique single-arm escapement with double wheels, some with temperature compensation of the pendulum, some with two dials, one showing the time and the other the calendar and often other information such as the phases of the moon , the times of sunrise and sunset in Paris, etc. The company was awarded a First Class prize at the Paris World Exhibition in 1857 for a commercial clock of this type.
