Catalogue description
Dealer description — S.Song Watches
The Omega Seamaster 300 is perhaps one of the most iconic and enduring watch models of all time. Alongside the Speedmaster and Railmaster, these models were first released by Omega in 1957 and are collectively known as the Trilogy. It was done as an effort by Omega to get into the tool watch game, as more an more people were leading active lifestyles. This version, launched in 1964, is the second big change in the Seamaster line. It replaced the earlier straight-lug Seamaster 300 and moved on to a more muscular lyre-lug asymmetrical case. This was very similar to how the Speedmaster changed as well, giving an indication to the closeness of these models. The Ref. 166.024 is the date version and apart from the bigger case, also featured a thick bakelite bezel with lume. With its case size measuring at 41mm, it is a very masculine watch that has a great presence on the wrist. Not only that, despite its large size, it sits very nicely on the wrist due to its relatively slim profile. The Seamster 300 cases were produced by two companies, Huguenin Freres and Central Boites, with this example being made by the former, as denoted by the stamping on the inner caseback. Flip the watch over and you will see that this Omega Seamster 300 is powered by one of their greatest workhorse movements, the Cal. 565. This self-winding movement is well known for its reliability and has a power reserve of 50 hours. Furthermore, this example comes in an absolutely pristine condition with great patina and a well-preserved bezel, dial and case. Topped with a flat link bracelet that completes the look, this Omega Seamster 300 Ref. 166.024 is a bonafide classic, instantly recognisable and enduringly iconic.

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.
