The pushers and the Omega signed crown are crisp and actuate smoothly. The sapphire crystal is clean and unmarred, offering an unobstructed view of the complex dial below. The solid caseback features a deeply engraved Speedmaster seahorse medallion, which remains crisp and well defined, alongside the clearly legible serial number engraving.

Movement

Close inspection of the movement reveals meticulous finishing, including circular graining on the base plates and Geneva waves across the winding rotor, which bears the clear OMEGA 1151 engraving. The components present beautifully, with no signs of tarnishing, moisture intrusion, or mishandling. Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece.

History
