Historical context
Early Modern Horology (1600 – 1750)
Huygens' pendulum and balance spring transform accuracy; English makers develop the anchor and deadbeat escapements.
Huygens's pendulum (1656–57) improved clock accuracy from about a quarter of an hour to under a minute a day. The anchor escapement (c. 1670) and the long seconds pendulum created the longcase clock; London makers such as Fromanteel, Knibb, Tompion and Quare led European clockmaking, and French makers created the Boulle pendule.

Carriage and travel clocks
The carriage clock is a portable spring clock with a balance-wheel escapement and a brass case with glass panels and a carrying handle. Abraham-Louis Breguet made early examples around 1800, and from the 1830s Paul Garnier and other French makers industrialised production, with the small towns of Saint-Nicolas-d'Aliermont and the Franche-Comté supplying movements for retailers worldwide.
Typical features include a platform escapement mounted horizontally on top of the movement (usually a lever, sometimes cylinder or Garnier's chaff-cutter), striking or repeating work, and alarms. English carriage clocks, generally larger and with fusees, were made by firms such as Frodsham and Dent. Travel clocks in folding leather cases became popular in the twentieth century.
What to look for
- A platform escapement visible through the top glass.
- Case styles: corniche, gorge, anglaise, obis or engraved cases.
- Repeat buttons on top and strike/silent levers.
- Stamps of movement makers (e.g. Drocourt, Jacot, Margaine, Richard & Co.) on the backplate.
Dating clues
- Early carriage clocks with Breguet or Garnier features: c. 1800–1850.
- Mass-produced French carriage clocks: c. 1850–1914.
- Folding travel clocks and alarm travel clocks: mostly 1920–1970.
