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).
