The first carriage clock was invented by Abraham-Louis Breguet for the Emperor Napoleon in 1812.
The case, usually plain or gilt-brass, is rectangular with a carrying handle and often set with glass or more rarely enamel or porcelain panels.
A feature of carriage clocks is the platform escapement, sometimes visible through a glazed aperture on the top of the case.
The factory of Armand Couaillet, in Saint-Nicolas d'Aliermont, France, made thousands of carriage clocks between 1880 and 1920.
A carriage clock has in the past been a traditional gift from employers to retiring or long-serving staff.
