Doxa Sub 300T Professional (Synchron Era), 1970s

Dealer description — Craft & Tailored

Doxa S.A. was founded in 1889 by Georges Ducommun as a maker of dress watches and other timepieces. In the late 1960s, Doxa decided to dedicate resources to produce a timepiece to be used exclusively for diving. Doxa consulted with various Navy dive teams and divers including Jacques Cousteau who was then chairman of "U.S. Divers." Doxa's innovative watches were quickly adopted by both commercial and military divers. Jacques 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. The Doxa company went through many acquisitions and changed ownership a few times over the years. Synchron bought Doxa in the late 1960s and added the brand to a group that also included Ernest Borel and Cyma, and was purchase again in 1978 by the Aubry Freres Company. The second-generation or “Synchron Era" as many refer to it, was aimed to be the watch of choice for the emerging recreational diving community. With sturdy cases, high visibility dials, and smart bezel design, the Synchron era Doxa Subs quickly became the watch of choice for recreational divers in both America and Europe.
