Doxa Sub 300 'Blacklung'

Doxa Sub 300 'Blacklung'

Why We Love It

Here at Analog/Shift - we aren't shy about our love of DOXA.  

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 - the uni-direcitonal bezel with the US Navy's no-decompression dive timing marks engraved, expanding bracelet, and oversized luminous minute hands to name but a few. 

Within the 42mm case lays a bright orange dial featuring the prototype 'aqualung' logo. Extremely scarce on the vintage market, early Sub 300 black lungs command the immediate attention of diver collectors. With the reissue of this model in 2017, the original versions of the Sub 300 from the late 60's are seen in high regard in the eyes of collectors. 

Among the rarest iteration of the iconic DOXA Sub 300, this particular example is in spectacular condition - nothing short of collector-grade.

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.
