Quick TakeSlap on the DOXA SUB 300 Divingstar and you're instantly injecting a shot of pure, unadulterated sunshine into your day, even if you're miles from the coast. That bright yellow dial isn't just for show; it's a nod to DOXA's history of prioritizing underwater visibility, wrapped up in a package that screams retro-cool confidence. But don't let the cheerful face fool you – this is a serious piece of kit. Beneath that domed sapphire crystal beats a COSC-certified heart, ticking away with chronometer precision. The tough-as-nails 316L steel case, complete with its screw-down crown and back, is ready for depths down to 300 meters. Add the legendary DOXA unidirectional bezel with its no-decompression scale, and you've got a genuine tool watch that traces its lineage directly back to the pioneering days of sport diving. Whether you rock it on the vintage-vibes "Beads of Rice" bracelet or the comfortable, color-matched rubber strap, the Divingstar is pure functional fun, a capable underwater companion with charisma to spare.

DescriptionThe Doxa SUB 300 Divingstar, reference 821.10.361.31, features a robust case constructed from high-grade 316L stainless steel. Dimensional specifications measure 42.50 mm in diameter across the flat sections and 45.00 mm across the widest point, with a total height profile of 13.40 mm. Case integrity under pressure is ensured by a screw-down stainless steel case back and a screw-down crown mechanism, contributing to a water resistance rating of 30 ATM, which corresponds to 300 meters or approximately 984 feet. Protecting the dial is a scratch-resistant sapphire crystal, shaped with a dome reminiscent of the original 1967 model's plexiglass but incorporating modern anti-reflective treatment for enhanced clarity. A key functional element is the unidirectional rotating bezel, a DOXA patented design, calibrated in meters. This bezel includes a dual scale indicating dive time in minutes and depth in meters, facilitating calculations for no-stop decompression dive ascents. The lug width is standardized at 20.00 mm, accommodating specified strap options.

Powering the timekeeping functions (hours, minutes, seconds, and a date indication positioned at the 3 o'clock aperture) is a Swiss mechanical automatic movement. 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. Significantly, the movement has achieved COSC Certified Chronometer status, validating its high degree of precision, reliability, and robustness under standardized testing conditions. DOXA applies decorative finishing to the movement components. The iconic dial design is treated with Super-LumiNova luminescent material on all dive-related indices and hands, ensuring optimal legibility in low-light underwater environments. The watch is offered with either a stainless steel "Beads of Rice" bracelet featuring a folding clasp equipped with a wetsuit extension, or an FKM rubber strap matching the dial color, which also utilizes a folding clasp incorporating a ratcheting wetsuit extension and the distinctive DOXA fish symbol.
