Quick TakePlunge into the deep blue with the SUB 300T Caribbean strapped to your wrist! Feel the heft of that solid 316L steel, a reassuring weight promising durability whether you're exploring wrecks 1,200 meters down or just navigating the urban jungle. Its lineage traces back to the legendary Conquistador, the first public diver with an HRV – a feature this modern iteration proudly carries, ready for serious saturation dives. That iconic Caribbean blue dial isn't just for show; paired with the unidirectional bezel's no-decompression scale (marked in feet, a cool nod) and Super-LumiNova® markers, it’s a highly legible command center for underwater timing. The sapphire crystal shrugs off scratches, while the smooth sweep of the seconds hand, driven by the reliable Swiss automatic movement ticking at a brisk 4 Hz, reminds you that adventure runs on precision time. Adjust the brilliant "Beads of Rice" bracelet over your wetsuit with the ratcheting clasp, and you're ready to make some waves. It's a tool, yes, but one with undeniable vintage soul and modern muscle.

DescriptionFabricated utilizing high-grade 316L stainless steel, the case structure of the SUB 300T Caribbean presents specific dimensional parameters measuring 42.50 mm in diameter and 44.50 mm lug-to-lug, with a total height profile of 13.65 mm. Engineering tolerances ensure integrity under substantial environmental stress, further guaranteed by a robust screw-down case back, also constructed from stainless steel, and a screw-down crown mechanism. These elements contribute significantly to the timepiece's considerable hydrostatic pressure rating, certified to 120 atmospheres, which translates to a water resistance depth of 1,200 meters or 3,937 feet. Protection for the dial is afforded by a scratch-resistant sapphire crystal, enhanced with an anti-reflective coating to maintain optimal visibility under various lighting conditions, a crucial factor for subaquatic legibility. A key functional component for saturation diving, the integrated helium release valve (HRV), is incorporated into the case design, allowing trapped helium molecules to escape during decompression, preserving the structural integrity of the watch. The design pays homage to the original 1968 SUB 300T Conquistador, integrating modern technical refinements suitable for contemporary high-performance diving applications while maintaining the established aesthetic lineage.

Powering the timekeeping functions is a Swiss-origin mechanical movement characterized by its automatic self-winding capability. Operating at a standard frequency of 28,800 vibrations per hour (4.0 Hz), the caliber provides a power reserve autonomously sustained for approximately 38 hours when fully wound. Doxa applies decorative finishing to the movement components, visible should the case back be removed for servicing. Core time indications include central hours, minutes, and seconds hands, supplemented by a date complication displayed through an aperture on the iconic dial face. Ensuring critical dive time information is readily available, the patented unidirectional rotating bezel is calibrated in feet and features an integrated no-decompression dive time calculator. Luminescence is addressed through the application of Super-LumiNova® inserts on all dive-relevant elements, including hands and markers, maximizing readability in low-light underwater environments. Attachment to the wrist is facilitated by either a stainless steel "Beads of Rice" bracelet or an FKM rubber strap, both options incorporating a folding clasp equipped with a ratcheting wetsuit extension mechanism for adjustability over dive suits. The interface point between the case and the bracelet/strap is standardized at a lug width of 20.00 mm.
