Quick TakePop that bright yellow dial on your wrist and tell me you don't feel a surge of retro-cool adventure energy. The DOXA SUB 300T Divingstar isn't just a dive watch; it's a callback to the pioneers, the guys who strapped on the original Conquistador and plunged into the unknown. But this ain't just a museum piece. Packed inside that chunky, undeniably tool-like 42.5mm steel case is some serious modern capability. We're talking 1200 meters of water resistance – that's deep enough to make whales nervous – plus the helium release valve for those who actually do saturation dives (or just like knowing it's there). The automatic movement keeps ticking reliably, the sapphire crystal shrugs off scratches, and that famous beads-of-rice bracelet? Pure comfort and vintage flair, with a wetsuit extension just in case you actually get it wet. It's a conversation starter, a serious diver, and a bright slice of sunshine on your arm, all rolled into one.
DescriptionThis timepiece incorporates a Swiss mechanical automatic movement, operating via self-winding mechanisms. Its operational frequency is registered at 28,800 vibrations per hour (equivalent to 4.0 Hz), providing a power reserve of approximately 38 hours. The movement, enhanced with custom decoration by DOXA, ensures reliable timekeeping with indications for hours, minutes, and seconds, complemented by a date display function. The integration of a helium release valve is a critical feature for saturation diving applications, allowing trapped helium atoms to escape during decompression, thereby protecting the integrity of the crystal and case structure under significant pressure differentials experienced in hyperbaric environments.
Constructed entirely from high-grade 316L stainless steel, the case presents dimensions of 42.50 mm in diameter and 44.50 mm lug-to-lug, with a total height of 13.65 mm. Water resistance is engineered to 120 ATM, corresponding to a depth rating of 1,200 meters or 3,937 feet, facilitated by a screw-down crown and a solid stainless steel screw-down case back. Protecting the iconic dial is a scratch-resistant sapphire crystal treated with an anti-reflective coating to maximize legibility under various lighting conditions. A key functional element is the patented unidirectional rotating bezel, calibrated in feet, which includes an integrated no-decompression dive time calculator. Luminescent Super-LumiNova® inserts are applied to all dive-relevant markers and hands, ensuring visibility in low-light underwater conditions. The watch secures to the wrist via a 20.00 mm lug width, accommodating either a stainless steel "Beads of Rice" bracelet or an FKM rubber strap, both equipped with a folding clasp featuring a practical ratcheting wetsuit extension mechanism.
