Quick TakeTalk about a conversation starter! This SUB 300 Carbon Professional isn't just wearing a modern suit; it IS the modern suit. Ditching steel for that stealthy, swirly forged carbon gives it this super lightweight, almost futuristic vibe, yet it still screams classic DOXA diver. You get that iconic Professional orange dial popping against the dark, textured carbon – it’s like a safety cone meeting a stealth fighter. Inside, the COSC-certified ticker ensures it's not just a pretty face; this thing is built for accuracy whether you're timing a dive decompression stop or just making sure you're not late for lunch. The domed sapphire crystal adds a touch of vintage charm, nodding to its ancestors, while the bright lume and proper 300-meter water resistance mean it’s genuinely ready for action. The rubber strap with that slick PVD clasp and dive extension seals the deal – it's comfy, secure, and totally functional. It’s the SUB 300 legend, reimagined for today's tech-savvy adventurer.

DescriptionThe timepiece designated SUB 300 Carbon, reference 822.70.351.21, utilizes a case constructed from forged carbon, offering a unique aesthetic and reduced mass. Dimensional specifications measure 42.50 mm in width and 45.00 mm lug-to-lug, with a total height profile of 13.40 mm. Ensuring structural integrity and water resistance, the movement is housed within a pressure-resistant titanium chamber, complemented by a screw-down titanium case back and a screw-down winding crown. Water resistance is rated to 30 atmospheres, which corresponds to a depth of 300 meters or approximately 984 feet, suitable for professional diving applications. Protecting the dial is a domed sapphire crystal featuring an anti-reflective treatment to enhance legibility under various lighting conditions. The unidirectional rotating bezel, also crafted from carbon, incorporates markings calibrated in meters for dive time tracking.

Powering the watch is a Swiss mechanical automatic movement, confirmed via its COSC Certified Chronometer status, which guarantees adherence to stringent accuracy and reliability standards. This self-winding caliber operates at a frequency of 28,800 vibrations per hour (4.0 Hz) and provides a power reserve of approximately 38 hours when fully wound. Decoration applied by Doxa enhances the movement's visual aspect, although it is concealed behind the solid titanium case back. Time indication includes central hours, minutes, and seconds hands, along with a date display located within an aperture at the 3 o'clock position. The iconic dial design ensures clarity, further augmented by the application of Super-LumiNova luminescent material to all dive-related indices and hands for optimal visibility in low-light underwater environments. Attachment to the wrist is facilitated by an FKM rubber strap with a 20.00 mm lug width, secured by a folding clasp featuring a black PVD coating and an adjustable ratcheting wetsuit extension mechanism, decorated with the DOXA fish symbol.
