A fine and rare late 19th century model of a detent chronometer escapement under original glass dome

The 3.25 inch uncompensated brass balance wheel supported by a pair of brass pillars and jewelled balance bridge, with blued steel helical hairspring and spring detent escapement mounted on a circular brass plate, the whole raised on a turned ebonised base with three ball feet. Wound to the underside by a winding key. Currently ticking. 24cms (9.5ins) high.

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.
