Catalogue description
Dealer description — Bulang & Sons
The Omega Seamaster line was originally introduced in 1948, but it wasn’t until 1957 that the Seamaster 300 made its debut (ref. CK2913) as a true professional dive watch—launched alongside the Speedmaster and Railmaster in the iconic “Master Trilogy.” The reference 166.024 was introduced around 1964–1965, replacing earlier Seamaster 300 models with several significant updates in both design and functionality. The Omega Seamaster 300 reference 166.024 is one of the most iconic vintage dive watches ever made. Introduced in the mid-1960s, it represents the golden age of tool watches and is highly respected among collectors for its robust construction, military associations, and timeless aesthetics. The 41mm “twisted lugs” case is in excellent condition, paired with a 60-click bezel that’s equally well-preserved. The dial has developed a beautiful beige patina over the years and features sharp, military-style sword hands that complete the look perfectly. The flat link bracelet (reference 1039) is also in great condition, with end links marked 516 and a clasp stamped 4/69. This cool tool watch has been fully serviced by our watchmaker and is ready for many more adventures in the years to come. Whether you're a seasoned collector or a first-time vintage buyer, this Seamaster 300 is a standout example of Omega's tool-watch legacy. Don't miss your chance to own a true classic.

Atlas type guide
Dive and water-resistant watches
Keeping water and dust out of a wristwatch was a long-standing challenge. Rolex's screw-down Oyster case (1926) and Omega's Marine (1932) were landmarks; in the early 1950s Blancpain's Fifty Fathoms and Rolex's Submariner defined the professional dive watch with rotating bezels for timing dives, luminous dials and high water resistance. The ISO 6425 standard (1982) later codified what a 'diver's watch' must do.
Dive watches became icons of post-war design and exploration, and their evolution — helium escape valves, ceramic bezels, saturation-diving depth ratings — records the history of underwater work.
What to look for
- Unidirectional or bidirectional rotating bezel with minute markings.
- Screw-down crown and case back; depth rating printed on the dial.
- Luminous hands and markers (radium before c. 1960, tritium c. 1960–1998, then Super-LumiNova).
- Reference numbers on the case between the lugs or inside the back.
Dating clues
- Screw-down Oyster cases: from 1926.
- Professional dive watches: from 1953.
- Tritium 'T' marks on dials: c. 1960–1998.
