Isaac-Daniel Piguet (1775-1841) was born in Le Chenit (Vaud) and is said to have moved to Geneva before 1800. He entered into partnership with his brother-in-law Henri Capt, another mécanicien, on 10 February 1802. The firm was active for a short period 1802 to 1811. Piguet & Capt were the first to make objects to combine automata and music for use in luxury objects, such as snuff boxes, jewelry and watches. The present lot is a fine example of a musical ring, combined with a watch, and retains its original box and key.
