History Introduced in 1948 to celebrate Omega's 100th anniversary, the Seamaster is the oldest line in the current collection. Originally conceived as a robust, water-resistant dress watch for active individuals, it drew inspiration from the waterproof watches Omega supplied to the British military during World War II. By the 1970s, the Seamaster line had expanded to include a wide variety of case shapes and complications, reflecting the dynamic design trends of the decade. The Caliber 1020, introduced in the early 1970s, was a high-frequency movement that offered a quickset day and date, representing a significant technical advancement for Omega's everyday watches. / Second Vintage SKU: OME-OSA-0004
