Quick TakeImagine strapping on a piece of pure, distilled dive heritage, yet it feels impossibly light, almost futuristic. That's the SUB 300 Carbon Professional. It’s got that unmistakable DOXA DNA – the bold orange dial screaming 'tool watch' function, the iconic cushion case shape – but rendered in marbled, stealthy forged carbon. It's like the original SUB 300 went through a high-tech metamorphosis. Inside beats a COSC-certified heart, ticking away with chronometer precision, ready for depths down to 300 meters thanks to its titanium inner chamber and screw-down crown. The domed sapphire crystal nods to the past's plexiglass curves, while the carbon bezel offers a modern tactile experience. It’s serious tech wrapped in avant-garde style, equally at home exploring a reef or navigating the urban sprawl. The FKM rubber strap with its PVD clasp and dive extension seals the deal – comfortable, secure, and ready for absolutely anything. It’s not just a watch; it's a statement piece that performs.

DescriptionEngineered with a forged carbon casing, this timepiece presents dimensions of 42.50 mm in diameter and 45.00 mm lug-to-lug, alongside a vertical measurement of 13.40 mm. Within this structure resides a pressure-resistant chamber constructed from titanium, which also forms the screw-down case back, ensuring structural integrity under demanding conditions. The incorporation of a screw-down crown is fundamental to achieving its significant water resistance rating, specified at 30 ATM, equivalent to 300 meters or approximately 984 feet. This capability designates the watch for serious underwater activities. Operational timing is facilitated by a unidirectional rotating bezel, also crafted from carbon, featuring metric dive time demarcations. Visibility is optimized through the application of Super-LumiNova® coating on all dive-pertinent indicators, guaranteeing legibility in low ambient light scenarios, a critical factor for diver safety. The watch face is protected by a domed sapphire crystal, selected for its high scratch resistance and treated with an anti-reflective coating to minimize glare and enhance readability under various lighting conditions.

Powering the instrument is a Swiss mechanical automatic movement, noted for its self-winding capability and prestigious COSC Certified Chronometer status, signifying adherence to stringent accuracy and reliability standards. This movement operates at a frequency of 28,800 vibrations per hour (4.0 Hz) and offers a power reserve of 38 hours when fully wound. The caliber features decoration applied by DOXA. Timekeeping functions include the display of hours, minutes, and central seconds, complemented by a date indication positioned within an aperture at the 3 o'clock mark. The watch is paired with an FKM rubber strap, selected for its durability and comfort, featuring a lug width of 20.00 mm. Security is provided by a folding clasp treated with a black PVD coating for enhanced resilience and aesthetics, which includes a ratcheting wetsuit extension mechanism allowing for easy adjustment over diving gear. The clasp is further embellished with the Doxa fish symbol.
