Quick TakeStrap this deep-sea legend on your wrist and feel the heritage pulse. The SUB 300T Caribbean isn't just a watch; it's a direct line to DOXA's pioneering spirit, updated for today's adventurers. Imagine gripping the patented bezel, its no-decompression scale a silent promise of safe exploration beneath the waves. The robust 316L steel case, confidently sized at 42.5mm, feels indestructible, ready for pressures up to 1200 meters – depths few dare to tread. Inside, the reliable Swiss automatic heart beats steadily, a testament to mechanical mastery. Glancing down, the vibrant Caribbean blue dial pops, legible even in the murky deep thanks to generous Super-LumiNova. It’s more than timekeeping; it's about trusting your gear when it counts. The helium release valve whispers tales of saturation dives, while the choice between the classic 'Beads of Rice' bracelet or the practical FKM rubber strap ensures comfort whether you're over a wetsuit or under a cuff. This isn't just inspired by history; it's built to make more.
DescriptionManufacturing protocols dictate the utilization of 316L stainless steel for the primary case structure, selected for its corrosion resistance and durability under demanding marine conditions. The case geometry is defined by a diameter of 42.50 mm and a lug-to-lug dimension of 44.50 mm, with a total structural height of 13.65 mm. Ensuring maximal integrity against water ingress, the design incorporates a screw-down crown mechanism and a solid stainless steel screw-down case back. Water resistance capability is certified to 120 atmospheres, equivalent to a depth of 1,200 meters or 3,937 feet, accommodating saturation diving operations. Central to its functionality as a diver's instrument is the patented unidirectional rotating bezel, calibrated in feet and incorporating an integrated no-decompression dive time calculator. A Helium Release Valve (HRV) is integrated into the case architecture, facilitating the safe release of trapped helium molecules during decompression phases typical of extended saturation dives, thereby preserving the structural integrity of the watch, particularly the crystal seating.
Beneath the protective sapphire crystal, treated with an anti-reflective coating to mitigate glare and enhance readability in various lighting conditions, resides the iconic Caribbean blue dial. Time indication is provided via centrally mounted hour, minute, and second hands, alongside a date aperture. All elements critical for dive timing and orientation, including indices and hands, are treated with Super-LumiNova luminescent material, guaranteeing optimal legibility in low-light underwater environments. Propulsion is achieved through a Swiss mechanical automatic movement, operating at a frequency of 28,800 vibrations per hour (4.0 Hz). This self-winding caliber provides a power reserve of approximately 38 hours when fully wound and features decoration applied by DOXA. The interface between the case and the wearer is established via a lug width of 20.00 mm, accommodating either a stainless steel "Beads of Rice" bracelet or an FKM rubber strap. Both options are equipped with a folding clasp incorporating a ratcheting wetsuit extension for secure and adaptable fitting over dive suits.
