Which Omega watch collection was introduced in 1948 to mark the company’s 100th anniversary?

The Omega Seamaster collection was introduced in 1948 to mark Omega’s 100th anniversary.

Omega based the original Seamaster on waterproof watches the company had made for the British military during the Second World War. The early model used a rubber O-ring gasket, a technology adapted from submarine engineering, to improve resistance to water and temperature changes.

The collection later developed into several branches, including dress-oriented models and professional diving watches. The Seamaster 300, introduced in 1957, was a dedicated diver’s model, while the Seamaster Professional Diver 300M became especially recognizable through its association with James Bond films.

The 1948 launch should not be confused with the 1957 introduction of the Seamaster 300. The broader Seamaster family began in 1948; the later Seamaster 300 added a more specialized diving identity. This distinction explains why both dates frequently appear in histories of the collection.
