DOXA Sub 300 Searambler 'Silver Lung'

DOXA Sub 300 Searambler 'Silver Lung'

Why We Love It

Here at Analog:Shift, we’re known for our love of DOXA.

In any flavor, any color, from the common yet wonderful orange-dialed Sub 300T Professional to the black-dialed Sharkhunter, the Army, and anything in between, we’ve counted them in our personal collection and offered them on our site.

But our love of the brand doesn’t end with the vintage versions. DOXA is still around, churning out awesome contemporary reissues of some of their golden-era classic. Such is the case with this watch, a limited edition 300 Searamber 'Silver Lung' which tributes the partnership between DOXA and Aqua Lung first formed in the late 1960s.

This particular example features all of the quintessential DOXA Sub features that we all love with the added benefit of the Aqua Lung logo printed on the dial. Colloquially known as 'Silver Lungs' to enthusiasts, this is a rare configuration and arguably the most sought-out of the Sub 300 reissue series.

Limited to 300 pieces worldwide, this watch is in outstanding condition throughout and is accompanied by its watch tube, COSC papers, additional links, and warranty card numbered 57/300 and dated 2018.

Now's your chance to grab one of the most popular contemporary homages to one of the unsung heroes in the development of the modern dive watch - don't miss it! 

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.
