This rare, manual-winding stainless steel Omega Seamaster Ref. 105.001-62 with the Calibre 321 is in good vintage condition. The watch has been recently serviced and has perfect mechanical functionality.

With a round case, round pump pushers and long bevelled lugs, this is a classically vintage watch in its styling. Sized at 35.5mm and 12.7mm thick, the watch is discreet and elegant, working appropriately as a dress watch, as well as for casual wear.

The watch carries the manual-winding, Calibre 321 at its heart, beating at a rate of 18,000 A/h, with a power reserve of approximately 50 hours. This is perhaps the manufacture’s most famous movement, with the same column wheel movement being found on the early Speedmasters, that were worn on the moon. Based of a Lemania ebauche, the greatness of this movement is manifested through haute-horlogerie manufactures such as Patek Philippe and Vacheron Constantin, using it for their own chronographs, even up to recently.

Our preowned watches have all undergone thorough mechanical inspections, including being ultrasonically cleaned, polished, resealed if appropriate and tested for at least four days, to ensure they meet our highest timekeeping standards.
