Pocket watch · Open-face key-wound pocket watch

This 19th-century Swiss pocket watch is an open-face, key-wound timepiece constructed in 18-karat gold. The watch is decorated with translucent green engine-turned enamel and inset diamonds in a central oval motif on the reverse. The original dial is gold with an engine-turned pattern, black Roman numerals, and blued steel Breguet-style hands. The watch is accompanied by a leather storage case, a winding key, and a separate white enamel spare dial featuring Roman numerals. The internal gold cuvette is engraved with the maker's mark 'D & C'. The gilt bar movement incorporates a suspended going barrel, a polished steel regulator, a simple three-spoke gilt balance, and a blued steel hairspring. The escapement is a polished steel cylinder type. The current assembly, along with its accessories, fits into a fitted rectangular case.
