The Omega Seamaster 300 began its life in 1957 with the ref. CK2913, released alongside the Railmaster CK2914 and Speedmaster CK2915 to form the legendary "Master Trilogy." While the Seamaster name dates back to the 1940s, the SM300 was Omega’s first true dive watch—built for serious underwater use and officially rated to 200m (though tested to 300m, hence the name).

The CK2913 features a 38mm “straight-lug” case, a thin bi-directional bakelite bezel, and a clean, legible black dial. It was only in production for a slender four years before being replaced by the CK14755. Much like the early no-crown-guard Rolex Submariners, however, Omega experimented with a large variety of design elements during its brief run. 

The present watch, a CK2913-3, is the first example we’ve had in over a year—and what a watch it is. The original radium dial has beautifully tropicalised, giving it a rich and striking appearance. All of the radium markers are intact and glow brightly under UV. The “small broad arrow” hour hand and the white lollipop seconds hand are both in fantastic condition. While the case has been lightly polished in the past, it remains full and sharp. Most impressively, the original bakelite bezel insert is completely intact—an extremely rare occurrence on this reference. 

An "Extract from the Archives" from Omega confirms the watch was originally delivered to Gibraltar on March 26, 1958. Nearly 70 years later, it still holds all its charm and character. The movement has been freshly checked and is running perfectly at +3 s/d, with 293 amplitude and a beat error of just 0.1 ms.

This is essentially Omega’s equivalent of the early Rolex “Big Crown” and “Small Crown” Submariners—but still at a comparatively attainable price point. The watch is absolutely gorgeous on the wrist - this OG SM300 is ready for its next chapter.
