Historical significance
- Round engraved watch. Case signed: Js Ls Jacot. Dome engraved: MOUVEMENT A 370 JOURS ECHAPPEMENT A CYLINDRE SEIZE TROUS EN RUBIS. Dial signed: F BOVET A BIENNE EN SUISSE. Movement signed: F BOVET A BIENNE. Circa 1880.
- The back of the gold case is engraved with a scene copied from a well-known painting by Léopold Robert (1794-1835) in the Louvre, The Arrival of the Reapers in the Pontine Marshes.
- This miniaturized copy testifies to the superlative skills of the casemaker, Jules Louis Jacot, who was born in Le Locle in 1826.
- The dial plate is decorated with a local landscape of a lake surrounded by mountains. The gold dial, engine-turned with concentric circles, has black enamelled Roman numerals.
- The gilded brass movement, with a power reserve of around one year, has a very long mainspring enclosed in a large barrel. Its cover, like the bridges, is engraved with a mille feuilles pattern, which became very fashionable in the 1890’s. The movement has a cylinder escapement. The watch is wound and set with a key.
