Omega introduced the Seamaster 300 in 1957, four years after the introduction of the first professional diving wristwatch – the Blancpain Fifty Fathoms – and the Rolex Submariner. The Seamaster 300 Replica wasn’t Omega’s first Seamaster, but it was the first true professional dive watch, receiving an official water resistance rating of 200 meters, the maximum depth to which the company could test its watches back then.
Together with the Speedmaster and the Railmaster, the Omega Replica Watches Seamaster 300 was part of a new trilogy of professional-grade wristwatches that used the same case and handset, the Seamaster 300 being aimed at professional divers. For practical reasons, Omega decided to manufacture all three pieces using the same base components, including the same cases and hands, but each piece would evolve to more specifically address the needs of the end user.
The first generation Best Omega Replica Seamaster 300, the ref. CK 2913-1, measured 39mm, and had straight lugs, a thin 60-minute bezel divided in 10-minute intervals, and broad arrow hands. The second generation, introduced seven years after the first, was 42mm, had chunkier twisted lugs, and also featured a wider bezel with hashes for every minute. Omega introduced two versions, the no-date ref. 165.024 and the ref. 166.024 with a date at three o’clock. The British armed forces gave the former model the nod.
