Omega Seamaster 300

Omega Seamaster 300

Why We Love It 

Like its bretheren, the Speedmaster and the Railmaster, the Seamaster was constantly evolving in its early years, with cosmetic tweaks and new subreferences appearing virtually every year. Combined with the batch manufacturing of the era, there are a variety of configurations and subtle changes for contemporary collectors to hone in on.

Also of note is the bezel. For those familiar with Seamaster 300s, the name 'Aldo' is well-known. For years, 'Aldo' bezels have been prized for their incredibly precise restoration of the rarely intact Bakelite inserts. Where factory-original SM 300 bezels can trade for more that $4,000 on the open market, 'Aldo' bezels command several thousands owing to their incredible fidelity to the originals and their acceptance among Omega collectors. This example here with its well preserved case, beautiful honest patina, and 'Aldo' bezel make for a truly rare and special watch at a very approachable price.

The Story 

Omega is no stranger to producing waterproof wristwatches. In 1932 the brand released the Omega Marine, which was worn by the father of the Aqua-Lung, Yves le Prieur, and descended to a depth of 14 meters with underwater explorer William Beebe in 1936.

It wasn't until the 1950s that diving would become a global phenomenon, and with it, the need for a new, reliable watch for professional and amateur divers alike. Early interest in the sport, rooted in the widespread fame of pioneers like Jacques Yves Cousteau was fueled by the exploits of adventurers, oceanographers and aquanauts like Jacques Piccard, Don Walsh and Robert Sténuit.

Omega went back to the drawing board and created a new watch in the hopes of competing with long-time rival Rolex for a place among divers. The new watch was released in 1957 and dubbed the Seamaster, alongside Omega's two other offerings from the same year, the Speedmaster and Railmaster- all three of them icons in their own right to this day.

While the Seamaster collection of waterproof watches had been in production since the 1940s, the Seamaster 300 released in 1957, the Reference CK 2913, was a turning point for the line, and in turn, Omega. Finally, they had created a robust, reliable diver with mass appeal. The CK 2913 was produced for several years successfully, until it was replaced with the CK 14.755 in 1960
