Vintage Omega Seamaster De Ville 14k Yellow Gold Fill U.S. Model LL6287-1 - 34,5mm - 1970

This vintage Omega Seamaster De Ville was produced in 1970 and is a special US-market model, specifically made for the American market. While the is identical to the regular Seamaster De Ville model, the entire case is gold-filled with 14-karat yellow gold. The dial differs slightly from the European version, featuring sandwich hour markers with black lacquer sides and gold centers wheres the European models are the other way around. The minute track is also more pronounced than on the European model.

The case is a Ross case, model 6287, housing a caliber 563 automatic movement that was overhauled in November 2025 and currently runs and functions perfectly.

We’ve paired this beautiful watch with a dark brown calf leather strap featuring a crocodile-grain motif and glossy finish. Overall, the watch is in great condition and makes for an excellent dress piece.
