Seamaster bumper from the early 1950s
A neatly presented Omega Seamaster bumper from circa 1951, this 36mm Staybrite steel case wears a period-proportioned profile with curved lugs, thin bezel and a restored dark-silver dial. The watch houses Omega’s calibre 351, a first‑generation bumper automatic with center seconds that illustrates the brand’s transition from early self-winding systems to later full-rotor automatics. Professionally serviced and fitted to a calf leather strap, it offers a refined mid‑century aesthetic paired with historically significant movement technology, appealing to collectors who value mechanical character and authentic period design.
