DOXA Sub 300T Divingstar

DOXA Sub 300T Divingstar

Why We Love It

We’re known for our love of DOXA Subs.

In any flavor, any color, from the classic orange-dialed Professional to the sophisticated black-dialed Sharkhunter, we love 'em all.

This 300T Divingstar with its bright yellow dial is like the Giant Squid: rare and elusive. Exact quantities of these watches are unknown, but when one surfaces on the vintage market, collectors take note. 

This particular Divingstar is a later version, released after DOXA was absorbed into the Synchron group, as evident by the group's logo engraved on the case back. Its dial and bezel assembly retain their vibrant colors, showing light even patina across its luminous indices and handset. 

Clean examples of vintage Divingstars such as this one truly do not surface often.

The Story

DOXA began Research and Development for the Sub 300 in 1964, under a team helmed by Urs Eschle, the brand's head of operations, who consulted professional divers including none other than the father of SCUBA himself, Jacques-Yves Cousteau.

Since wearability was crucial, Eschle designed a large case with wide rounded lugs. For the dial, the team tested many colors (orange, yellow, turquoise, and red) in the waters of Neuchatel Lake. An unprecedented amount of tritium was also used on the hands and hour indices. 

The team implemented a unidirectional bezel with an innovative insert: the U.S. Navy No Decompression chart, with the outer depth scale in orange and the minute scale in black, to allow divers to gauge how much air was in left in their tanks. Rounding out the Sub 300's innovative design was a beads-of-rice bracelet that was the first to implement an ratcheting expandable clasp capable of fitting over a diver's wetsuit without having to remove links.
