Doxa · Family: SUB 300 Carbon
The Doxa SUB 300 Carbon Professional 822.70.351.21 is the unlimited carbon-fiber edition of the brand's iconic SUB 300 dive watch, introduced in 2021 — more than 50 years after the 1967 original — with a 42.50mm case that pairs a carbon exterior with a pressure-resistant titanium inner casing. It runs an automatic three-hand movement with COSC chronometer certification and 38 hours of power reserve. Cazador has no verified price observations yet for this reference. Its standout detail: this is the first time Doxa has taken the SUB 300 into a material other than traditional steel.

Doxa was founded in 1889 in Le Locle, Switzerland, though its best-remembered dive-watch milestone came in 1967, when it launched the SUB 300: one of the first commercial dive watches designed together with diving professionals, sporting the orange "Professional" dial chosen for underwater visibility — a color no one else had used on a dive watch at the time, and one that became the brand's chromatic signature.
In 2021, more than 50 years after that launch, Doxa introduced the SUB 300 in an unlimited carbon edition for the first time, breaking with steel as the line's sole material. The case pairs a forged carbon exterior — light and highly resistant — with a titanium inner casing that shields the movement from pressure, a technical solution built to carry the SUB 300's classic design into edgier, more technical territory without giving up its certified 300 meters of water resistance.
Under the dial sits an automatic three-hand movement with COSC chronometer certification — the independent Swiss body that certifies movement accuracy — with 38 hours of power reserve and a date window at 3 o'clock, in line with the original SUB 300's classic layout. The domed sapphire crystal with anti-reflective treatment pays tribute to the curved plexiglass of the 1967 watch, while every dive-related marking carries a Super-LumiNova coating for legibility in low-visibility conditions.
The SUB 300 Carbon is offered in several dial colors, with a matching or black FKM rubber strap, a black PVD-coated folding clasp, and a ratcheting diving extension to fit over a wetsuit. This is the fourth Doxa reference in Cazador's catalog and the first in a material other than steel, alongside the SUB 200 and SUB 300T Professional already present.
