Omega launched the Seamaster as a civilian wristwatch collection in 1948.
Omega introduced the Seamaster in 1948 to mark the company’s 100th anniversary. The early collection drew on waterproofing ideas Omega had developed for military watches during the Second World War, but it was presented as a robust watch for civilian use rather than solely as military equipment.
The Seamaster name later became strongly associated with professional diving, especially after the Seamaster 300 appeared in 1957. That means the collection’s 1948 origin and the dedicated dive-watch line’s 1957 debut are different milestones. The Seamaster also became widely known through James Bond films, although screen models and real-world versions have changed over time.
