History The Seamaster Calendar reference 2849 was part of Omega's international collection from 1956 to 1962. It was introduced specifically to house the Caliber 503, which marked an important technical milestone as Omega's first full-rotor automatic movement featuring a date complication. Produced in a versatile 34.5mm case, this reference helped cement the Seamaster's reputation as a robust yet elegant daily companion during the mid-twentieth century. / Second Vintage SKU: OME-ASX-0017
