Omega Seamaster Calendar

About this reference

The Omega Seamaster Calendar reference 2627 was produced during the early 1950s, representing the first Seamaster model to feature a date complication. Collectors prioritize this reference for its caliber 353 or 355 bumper automatic movement and the distinct six o'clock position of the date window. The 18k pink gold execution is significantly rarer than the steel or gold-capped versions, often featuring heavy "beefy" lugs and a screw-down case back. On the secondary market, 18k pink gold examples typically range from $4,000 to $8,500 depending on the presence of original "waffle" or "honeycomb" dials and sharp case geometry. A notable production detail is the "Calendar" text placement, which is often found curved along the bottom of the dial. High-condition specimens with original pink gold crowns and markers have reached the upper end of this bracket at specialized auctions.
