Doxa has just announced a limited edition Black Lung version of their Sub 300 dive watch that dates back to 1967.

The case is made from a solid monoblock piece of stainless steel and measures 42.5 mm x 12.4 mm just like the limited edition 50th Anniversary Sub 300 re-issue.

In fact, the Sub 300 Black Lung is exactly the same as the aforementioned wristwatch, including the chronometer grade ETA 2824-2 automatic movement, “Professional” orange colored dial, and signature “beads of rice” bracelet with integrated wetsuit extension. The only exception is the official black and yellow Aqua-Lung logo on the dial between 6 and 9 o’clock.


Doxa x Aqua Lung diving knife will be available separately

A serrated, unidirectional timing bezel also displays a Doxa patented integrated “no deco” scale, engraved in orange, per the US Navy’s maximum no-decompression limits for safe recreational diving.

The watch features a double domed sapphire crystal designed like plexiglass from past models. A screw-down crown, screw-in caseback, and no less than four gaskets ensure water-resistance to 300 meters.


Aqua Lung is a legendary diving equipment company that developed the world’s first self-contained underwater breathing apparatus in 1943.

The Doxa Sub 300 “Black Lung” is expected to ship in December of this year, will be limited to 300 pieces with a retail price of $2,590 (pre-order price $2190).
