The Watch
The Doxa Sub 300T line is one of the brand's most recognizable watches. It was the first commercially made dive watch with various colour dials and no-decompression bezel. These watches were made with functionality in mind. From the burly shape of the case to the application of the maximum amount of tritium allowed by law on the dial for legibility, these tool watches were meant to be used.
Colours of the Original Sub300Ts were:
Yellow: Diving Star
Orange: Professional
Silver: Searambler
Black: Sharkhunter
The Sub300t's are one of the most iconic Vintage Dive Watches out there, Thanks in no small part to the Dive Icon Jacques Cousteau.

Jacques Cousteau owned and wore a Doxa Sub300T. Cousteau, who at the time was the head of U.S. Divers, was so impressed by the Doxa Sub300T that he became a distributor of the reference in the United States and co-branded the dial of the Sub300T with the U.S. Divers logo.


This particular Professional is in very good order and quite possibly all original, including boasting its very uncommon Original BoR Expandro Bracelet. The Watch dates from c.1968-1975, we know this as in 1968 Synchron purchased Doxa and started using their branding on the sub300t.
