This is a lovely, early Seamaster 300 reference 2913/7 with a big lollipop seconds hand, a small detail of which we think is great detail on these. To us, these watches have a cool, stealthy tool watch vibe that almost a little sinister! This is a very cool and great condition early SM300 that dates to 1961. The 36mm steel case is in excellent condition. The dial is in great condition and the hour markers have taken on a nice patina.. The bezel has been very nicely restored at some point, which is common with these watches. The watch comes with an Omega Archive extract confirming that the watch delivered to Austria in 1961. This cool SM300 diver is fitted with a reference 7912 steel bracelet with ref 6 endlinks and is stamped ‘2 61’.& caseback has a lovely engraving .The cal 501 movement has been fully serviced by our watchmaker.

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.
