Doxa Sub 300t Professional - US Divers Dial

Doxa Sub 300t Professional - US Divers Dial

In the late 1960s, DOXA developed the most important diver's watch you've never heard of.

The brand had numerous innovations that had an impact on the design and manufacture of sport and professional diving watches to this day; the world's first uni-directional rotating bezel with an engraved US Navy No-Decompression dive chart, the first commercially available Helium Release Valve (on the Conquistador models), and of course their signature Orange dial for maximum visibility underwater. DOXA, in our opinion, should be ranked and regarded among the other iconic divers - the Blancpain Fifty Fathoms and the Rolex Submariner.

Alas, the brand didn't have the staying power of the larger companies, and was lost in obscurity for decades after the quartz crisis, kept alive to a dedicated legion of enthusiasts only through the writings of adventure writer Clive Cussler, whose fictional hero wore an orange dial DOXA in many of his world-saving exploits.

But that doesn't mean we forgot about them! And as always, it is our mission to bring the most exceptional and storied vintage timepieces to market. So with that in mind, we're very pleased to present this absolutely immaculate example of an early 1970s Sub 300T Professional, complete with its orange dial and US Diver's "Aqua-Lung" logo, the stamp of approval from the Sea King himself, Jacques Cousteau. This is one of the cleanest vintage DOXAs we've ever come across!

If you consider yourself a fan of vintage diving watches, you need a DOXA in your collection... don't say you didn't get the memo.
