Mid‑1950s Omega Seamaster, caliber 501
A refined Seamaster from circa 1956, this Omega presents the restrained proportions and gold‑plated casework typical of mid‑century dress sports models. The 34 mm diameter and 41 mm lug‑to‑lug deliver balanced presence on the wrist, while an acrylic crystal and a professionally restored dial preserve the period look. Under the caseback sits the automatic caliber 501 with 20 jewels, a movement celebrated for steady daily performance in Omega’s postwar lineup. With its original crown, calf leather strap and a documented service from 20-03-2026, the watch offers a thoughtfully maintained example for a collector seeking classic Seamaster character.
