Thanks Gents Vintage 1969 Doxa Automatic Sub 300T ‘Sharkhunter’ Wrist Watch In 1969, Doxa launched the Sub 300T, the first general release diver’s wrist watch to feature a helium release valve. Still in operation today, the innovative and industry-leading Doxa company was founded back in 1889 by Georges Ducommun, an ambitious young craftsman who started out as a maker of exquisite, hand decorated pocket watches. Ducommun became an innovator within the industry in 1908, when he patented a pioneering 8-day mechanical watch movement that was placed in a larger case, creating the perfect timepiece for the new leisure pursuits of the era - aviation and motor cars. In the 1960s, when Jacques-Yves Cousteau co-developed the aqua-lung and popularized diving as a sport, Doxa decided to add a dive watch to its wristwatch collection, forming a research team with several professional divers to develop the Sub 300T, an affordable sports divers watch for both pros and recreational divers. The Doxa Sub 300T included many innovative features that we take for granted today but were revolutionary at the time. It’s still regarded as a reliable, comfortable and highly legible timepiece that’s as easy to use as it is easy on the eye. The ‘Sharkhunter’ was one of six Swiss-made Sub 300T models and is recognizable by its distinctive matte black dial. The model also has a rotatable steel bezel, screw down crown and features the Doxa yacht logo, crisply engraved on the case back. What’s on offer: This piece has recently been professionally serviced and pressure tested to 6-bar. It’s in full working order with a brand new unsigned crown and tube and is in excellent condition overall, with only a small, superficial mark on the crystal glass (this can be replaced should you wish, at your request).

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

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.
