Doxa SUB 300 carbon COSC

In 1967, DOXA launched the revolutionary SUB concept with the SUB 300, the first truly purpose-designed diver’s tool-watch that was also accessible to the general public.
The SUB 300 also became instantly recognizable – and legendary – for another reason: it was the first diver’s watch ever to sport a bright orange dial, contrasting with the traditional black or white dials so common on other diving watches of the time.

Following through on the great success of the SUB 300 Aqua Lung US Divers launched in 2020, a limited series of only 300 numbered pieces, DOXA Watches is bringing out the SUB 300 carbon COSC in a non-limited version, in 6 colors and 10 versions, vibrant, bright, summery and ready for adventure. The DOXA SUB 300 carbon also comes with a choice of rubber straps: tone-on-tone to match the color of the dial and, of course, black. The very soft rubber used for this series, with DOXA markings on both sides, makes the watch particularly comfortable to wear.

Besides a black PVD-coated folding clasp highlighted with the exclusive ‘DOXA fish’ symbol, the strap features an adjustable diver’s wetsuit extension.
Forged carbon provides DOXA with a high-tech, high appeal material to build on the heritage of the SUB 300.
More than 50 years after its launch, rich with a unique history, the legendary SUB 300 is available in 2021 for the first time in carbon as a non-limited version.


Uncannily lightweight compared to steel, forged carbon gives off an urban camouflage vibe that alternates shades of charcoal gray and black, an iridescent effect that fluctuates with the intensity of the light, turning the watch into a more radical, more contemporary statement.

Far from the usual black watch cases, the texture, the look and feel of forged carbon are simply one of a kind. Matte, raw, high tech, the material seems at once compact and irregular. The very particular non-homogeneous marbling – achieved with randomly worked fibers – expresses a subtle balance between being respectful of its heritage and yet provocative in the same way the original SUB 300 was back then.


The SUB 300 carbon echoes all the codes of its origins, while cultivating a racier, sportier, more technical, but also more urban look. The result is a touch of edginess that does not in the least betray the legend and instead, using a high-performance material at the service of its functionality, projects it into the future.
