Pocket chronometers and precision watches

A pocket chronometer is a watch built to observatory standards, traditionally with a detent escapement like a marine chronometer. English makers such as John Arnold and Thomas Earnshaw made the first pocket chronometers in the 1780s. In the nineteenth century the term increasingly referred to any watch that had passed official rating trials at observatories in Kew, Neuchâtel, Geneva or Besançon, and the Swiss lever chronometer became dominant.

Tourbillon and karrusel watches belong to the same world of precision. Breguet patented the tourbillon in 1801 to average out positional errors; Bahne Bonniksen's karrusel (1892) was a cheaper English alternative. Rating certificates (bulletins de marche) that accompany such watches are historical documents in their own right.
