Vacheron & Constantin open face pocketwatch, circa 1920, is a classic and beautiful example of timekeeping. The 47mm round case is .935 silver -- a higher standard than sterling silver -- with a silver cuvette, or inner back, porcelain dial with enameled black Breguet numerals, sunken subsidiary seconds dial, and gold Breguet hands and gold crown. The movement is 17J, warrantied by Aaron Faber for 12 months. Case, dial and movement signed. A great value!
