Footnotes

The detent escapement, a pivotal innovation in precision horology, was first invented in 1748 by the French clockmaker Pierre Le Roy. Later in the 18th century, both Thomas Earnshaw and John Arnold independently developed their own versions of this escapement, contributing significantly to its refinement and widespread adoption in marine chronometers.

Provenance:
Gerd-Rudiger Lang.
