Stunning 1955 Omega 2757 Seamaster Calendar solid 18K yellow gold man's watch in excellent original condition. Truly a unicorn in the Seamaster line. It is truly rare to find a 2757 in solid 18K yellow gold, and look at the condition of the case. Evidence of factory finish still on the case back and look how crisp the words "Seamaster" and "Waterproof" remain! Thick lugs and case all the way around. Original signed crystal. Original signed crown. Looking inside, the inner case back has no service marks and is basically untouched and pristine. The caliber 355 automatic movement is clean, running strong and keeping good time. The screw heads look like they have hardly been touched. The original black glossy dial with gold gilt font has achieved a chocolate/tiger's eye/tropical personality that seems to change with the angle and how the light hits it. Truly one of a kind. The case measures 34mm wide with 18mm lugs. If you are a Seamaster fan, this is undoubtedly quite a special watch bested by few. Authenticity unconditionally guaranteed.
