Breguet et fils à Paris

, Movement No. 4890, 200 x 160 x 170 mm, circa 1834

A French ship's chronometer - sold April 1st, 1834 to Monsieur Ducom, representative for Breguet in Bordeaux, for the price of 1800 Francs


Case: heavy mahogany box. Dial: silvered. Movm.: brass movement, 2 barrels, applied platform no. 213 with spring detent escapement according to Thomas Earnshaw, tripod adjusting device for the helical balance spring, chronometer balance with 4 weights and 6 screws, hack feature.

Despite the complex construction - which has, for example a very intricate holder for the balance that can be adjusted with three screws - the design of Breguet's chronometers allows for a very efficient production process. The train is not fitted between the main plates but sits underneath the dial, which makes it easily accessible. The escapement can be worked on without touching the rest of the movement - a locking lever stops the movement as soon as the balance mechanism is removed. For easy handling the construction is secured with a clamp mechanism that allows the chronometer to be removed from the gimbal without difficulty.
