DOXA Sub 300T Professional 'Aqua-Lung'

We aren't shy about our love of DOXA here at Analog:Shift.

The original inspiration behind Analog:Shift was squarely centered on DOXA! In any flavor, any color, from the classic orange-dialed Professional to the stunning silver-dialed Searambler, we love 'em all.

While perhaps not as well-known as the Blancpain Fifty-Fathoms or the Rolex Submariner, the DOXA Sub series played an integral role in the development of the modern diver's watch. The first generation of the model, introduced in 1967, brought innovations we now take for granted — a unidirectional bezel with the US Navy's no-decompression dive timing marks engraved, an expanding bracelet, brightly colored hi-legibility dial, and an oversized luminous minute hand to name but a few. 

The DOXA 'Professional', which features bright and stand-out orange dials, is perhaps the most sought-after configuration of the lineage.

This example, a 300T, features a 42mm cushion case with a unidirectional ‘No Deco’ bezel, a ‘DOXA’ signed locking crown, and a mineral crystal that sits flush against the inner bezel’s edge — a tell-tale characteristic of a 300T case.

True to its ‘Professional’ namesake, the bright orange dial features printed hour indices, an oversized minute hand, a dwarf hour hand, a date window at 3 o’clock, and an ‘Aqua Lung’ logo in the lower left quadrant, indicating original retail sale through Jacques Cousteau's US Diver's brand. The dial, luminous plots, bezel, and case all show just the right amount of wear and patina for its age and offers up loads of character and charm befitting a 50 year old diver's watch.

Fitted to a stainless steel Expandro 'beads-of-rice' bracelet equipped with a signed ratcheting clasp and expanding diver's extension, this piece is fresh off a professional service and ready wear on any adventure. 

Jacques Cousteau once said, “We must go and see for ourselves.”

Take The Captain's advice and see what this exceptional vintage DOXA is all about!

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.
