Breguet et Fils No. 106 is an early gilt-brass and octagonal mahogany boxed marine chronometer, representing the maker's earliest recorded sale of a marine chronometer.

Sold to Breguet's Bordeaux agent Monsieur Ducom on 11 January 1816, its ébauche is documented by certificate to have been made by Samuel Roy before 1800. The movement features twin barrels turning a single fusee, Harrison's maintaining power, an Earnshaw spring detent escapement on a kidney-shaped plate, and an Arnold three-arm compensation balance with a conical balance spring. The silvered matt dial displays Roman numerals and a large subsidiary seconds dial.
