The brand introduced the earliest Seamaster watches in 1948, just a few years after the end of WW2. Only four years later, in 1952, the first Omega featuring a date came to the market: it was the first Seamaster Calendar, reference 2627, fitted with caliber 353. Only two years after reference 2627 debuted, Omega released another model: it was the reference CK 2757 powered by caliber 355.
While the 2627 had a threaded caseback, the new 2757 had a press-in caseback, with the same water resistance (30m).
The case measures 35 mm and is found in various material combinations, including steel, gold, and steel/gold, as in the present example combining pink gold and stainless steel.
