Approx. Ø31mm, ca. 26g, 18K gold à-goutte, backside diamond rose trim (incomplete), work signed Vacheron & Constantin, made for Louis Rey Marseille, No. 120721, enamel dial, gilded hands, work needs overhaul/cleaning, balance swings freely. The Joaillerie Louis Rey (also known as the Joaillerie Rey) was a traditional French jeweller's and goldsmith's house in Marseille, France, which lasted for almost two centuries (1785–1962). The Vacheron number 120721 in the case lets the clock date to ca. 1850 and thus as a very early crown winding clock.
