DOXA SUB 300 Carbon COSC (New Models: Orange Professional, Silver Searambler, Black Sharkhunter, Navy Caribbean, Yellow Divingstar and Turquoise Aquamarine)

After the great success of the SUB 300 Aqua Lung US Divers launched in 2020, a limited series of only 300 numbered pieces, Swiss watch brand DOXA presents the SUB 300 carbon COSC in 6 colors: Orange Professional, Silver Searambler, Black Sharkhunter, Navy Caribbean, Yellow Divingstar and Turquoise Aquamarine.

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 textures, 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.

Each self-winding mechanical movement to equip a SUB 300 carbon COSC is rigorously certified by the prestigious COSC (for ‘Contrôle Officiel Suisse des Chronomètres’). COSC certification guarantees chronometric performance and scrupulous compliance with the highest standards in terms of precision, reliability, shock resistance, automatic winding and ease of maintenance.

The SUB 300 carbon COSC retains all the technical hallmarks that defined the legend. With a diameter of 42.5 mm, the SUB 300 carbon COSC features a pressure-resistant titanium chamber and a screw-down crown to afford maximum protection for the movement. The watch is waterproof to a depth of 300 meters or 30 ATM, about 980 feet, for absolute freedom of undersea exploration.

Its scratch-resistant sapphire crystal with anti-reflective treatment has the distinctive dome shape of the curved Plexiglas used for the original series way back when. The COSC-certified automatic movement provides a power reserve of approximately 38 hours.

All dive-related displays stand out in low-light conditions thanks to Super-LumiNova® luminescence, thus ensuring excellent readability during dives where visibility is reduced.

The hour indices are clearly visible, as is the dual indication of dive time in minutes and depth in meters on the patented unidirectional rotating bezel designed for calculating and monitoring no-decompression dive times.

For the dive time scale, the inserts are white, punctuated with a dot at 12 o’clock. The inserts of the bezel graduated in meters for depths are colored – either in orange, yellow or turquoise –for visual differentiation, with a light dot at 12H.
