Individual type · partial
Period
1821
This silver and gold pocket chronometer, No. 3595, was produced by Breguet et Fils and recorded as sent to Ducom on January 23, 1821. The watch is constructed with a three-body, "forme quatre baguettes" silver case, featuring gold hinges and a case back engraved with the initials "D.S."
A gilt brass detachable cuvette protects the movement. The dial is made of frosted silver with radial Roman numerals, a subsidiary seconds dial at the XII position, and outer dot minute markers. It is powered by a 24-ligne, frosted and gilt, three-quarter plate movement equipped with a fusee and chain, maintaining power, and a spring detent escapement. The compensation balance is a two-arm cut bimetallic type with cylindrical weights and gold timing screws, accompanied by a free-sprung blued steel helical balance spring.
The dial, cuvette, and movement are signed.
