Omega Seamaster_ A Guide to Vintage Diving Watch History
A guide to the history of vintage Omega Seamaster diving watches. Discover the innovations, designs, and notable models that shaped underwater exploration.

The Genesis of the Omega Seamaster Diving Watch Line
The Omega Seamaster, a name synonymous with robustness and elegance, began its life not as a dedicated dive watch, but as a rugged, waterproof timepiece designed for everyday wear. Introduced in 1948, the Seamaster drew inspiration from watches Omega supplied to the British military during World War II. These watches needed to withstand harsh conditions, and the Seamaster inherited that DNA.
Early Seamasters were known for their reliable automatic movements and impressive water resistance for the time. However, they weren't explicitly designed for diving. The real transformation into a true diver's watch came later, driven by the burgeoning recreational diving scene of the 1950s and 60s.
The Seamaster 300: Omega's First Serious Dive Watch (CK2913)
In 1957, Omega unveiled the Seamaster 300 (Reference CK2913), a watch that marked a significant step towards becoming a serious contender in the diving watch market. Despite the '300' in its name, it was actually tested to a depth of around 200 meters, not 300. The name was chosen for marketing reasons, suggesting a greater depth capability than competitors. The Seamaster 300 was designed as a competitor to the Rolex Submariner and the Blancpain Fifty Fathoms.
Key features of the original Seamaster 300 included:
- A rotating bezel for tracking elapsed dive time.
- Bold luminous markers for excellent legibility underwater.
- A robust case construction designed to withstand pressure.
- The reliable Omega Caliber 501 automatic movement.
The CK2913 had several variations, with different handset designs and dial configurations, making it a popular target for collectors today. A well-preserved CK2913 can fetch a premium price at auction.
Evolution of the Seamaster 300: From CK2913 to 165.024
The Seamaster 300 underwent several iterations in the years following its initial release. The reference 165.024, introduced in the early 1960s, is perhaps the most iconic Seamaster 300. It featured a cleaner dial design, sword hands, and a more refined bezel. The 165.024 was a favorite among professional divers and military personnel.
The 165.024 came with several movement options, including the Caliber 552 and the Caliber 565. It was also available with either a steel bracelet or a rubber strap, depending on the intended use.
The Seamaster 600 'PloProf': A Deep Dive into Innovation
In 1970, Omega pushed the boundaries of diving watch technology with the Seamaster 600, nicknamed the 'PloProf' (Plongeur Professionnel, French for professional diver). This watch was designed for saturation divers working at extreme depths, and it incorporated several innovative features:
- A monobloc case construction for exceptional water resistance.
- A unique bezel locking mechanism to prevent accidental adjustments.
- A prominent red button to release the bezel.
- An extra-thick crystal to withstand immense pressure.
The PloProf was tested to a depth of 600 meters (2000 feet), making it one of the most capable diving watches of its time. Its distinctive design, often described as 'industrial' or 'brutalist,' made it instantly recognizable. The PloProf remains a highly sought-after collectible, and Omega has even released modern re-editions of this iconic watch.
The Seamaster 1000: Another Deep-Sea Pioneer
Following the PloProf, Omega introduced the Seamaster 1000 in the early 1970s. This watch was also designed for saturation diving and was tested to a depth of 1000 meters (3300 feet). The Seamaster 1000 featured a large, asymmetrical case, a helium escape valve, and a highly legible dial. While not as visually striking as the PloProf, the Seamaster 1000 was a technologically advanced diving watch in its own right.
