Breguet Neveu & Cie, Paris, "Dépôt de la Marine", Movement No. 4884, Case No. 4884, 120 x 160 x 170 mm, circa 1844
A rare ship's chronometer with two barrels - sold 29th May 1844 to the Ministère de la Marine
Case: mahogany, with lid, slide and glass, original numbered ratchet key "8448". Dial: silvered. Movm.: brass movement, 79 mm, with separate numbered escapement plate no. 173, 2 barrels, spring detent escapement, tripod adjusting device for the balance spring, bimetallic chronometer balance with 2 weights and 4 screws.
Breguet was producing marine chronometers of a similar type since the early 19th century. Typical features are the two barrels and the lentil-shaped separate plate for the escapement. Despite the complex construction - which has, for example a very intricate holder for the balance that can be adjusted with three screws - the design 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.
This piece comes with the original numbered ratched wench, although it is not working anymore. The movement itself needs extensive cleaning.
