【OMEGA Seamaster / Manual Winding, 1950s-60s】 Currently running. The ticking sound, "tick...tick," of the low-beat movement is the calming heartbeat of a machine. It stops after about half a day after being hand-wound. Overhaul and strap replacement are likely needed. One owner, it belonged to my grandfather. There are fine scratches on the surface of the crystal (glass) due to aging. There is also age-related deterioration and dirt. Please replace the strap. I do not have specialized knowledge, so the details of the condition are unknown. I have included information I have researched, and there may be errors in my assessment. Please understand. The back cover has the "Waterproof Seamaster" engraving. It has a simple yet strong presence, and I feel a classical charm in this piece. It will be delivered as is. Please consider this with understanding. The following is only an assessment. • Manual winding model from the early 1950s-60s (Estimated Cal. 284-286 series) • Design: Early classical line (Bar index, thin hands) • Case: Stainless steel (silver), a clean face typical of Omega • Back cover engraving: "Waterproof Seamaster" Evidence of the early logo period • Charm: The quiet luxury that remains of the early Seamaster • Current condition: Running, requires overhaul #OMEGA #Omega #Seamaster #Seamaster #ManualWindingWatch #AntiqueWatch VintageOmega The calming heartbeat of a machine Omega Classic
