1970s DOXA Sub 300T Searambler (Ref. 11899 4)

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.

The Doxa company 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 Doxa Subs quickly became the watch of choice for recreational divers in both America and Europe.

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.
