Quick TakeSlipping on the SUB 300 Searambler isn't just strapping on a watch; it's like shaking hands with diving history, but with a modern twist. That silvery Searambler dial has a subtle cool factor the louder dial colors lack, shifting elegantly from tool-watch purebred to something surprisingly versatile topside. You feel the solid heft of the 316L steel case, a reassuring presence built for serious underwater pressure, backed by that 300-meter depth rating and the security of the screw-down crown. Inside, the COSC-certified automatic movement hums away—a guarantee of Swiss precision that’s more than just a spec sheet boast; it’s confidence you can rely on, whether timing a dive or just making it to your next meeting. Twisting the patented unidirectional bezel is pure mechanical satisfaction, the clicks sharp and defined, ready to track minutes below or time a pizza in the oven. And that domed sapphire crystal? It nails the vintage vibe while being tough as nails. It's a legend reborn, ready for adventure or just adding serious character to your daily grind.

DescriptionThe timepiece designated Doxa SUB 300 Searambler, reference 821.10.021.10, incorporates a Swiss origin mechanical movement characterized by automatic self-winding functionality. This movement has achieved Contrôle Officiel Suisse des Chronomètres (COSC) certification, attesting to its adherence to stringent standards for precision, robustness, and operational reliability under various conditions. Operational endurance is rated at a minimum of 38 hours of power reserve when fully wound. The oscillation frequency is specified at 28,800 vibrations per hour, equivalent to 4.0 Hertz, contributing to the stability of timekeeping. Internal decoration of the movement components is executed by DOXA. Time indication is provided via centrally mounted hour, minute, and second hands. A date complication is integrated, displayed through an aperture positioned at the 3 o'clock marker on the dial. All critical dive-related indices and hands are treated with Super-LumiNova® luminescent material to ensure optimal legibility in environments with diminished ambient light, a crucial factor for underwater applications.

Construction of the external housing utilizes high-grade 316L stainless steel, selected for its corrosion resistance and durability. The case presents dimensions of 42.50 mm in diameter and 45.00 mm lug-to-lug, with a vertical profile measurement (height) of 13.40 mm. Water integrity is ensured through the implementation of a screw-down crown mechanism and a solid stainless steel screw-down case back, achieving a water resistance rating certified to 30 atmospheres (ATM), which corresponds to a depth of 300 meters or approximately 984 feet. Protecting the dial is a scratch-resistant sapphire crystal, engineered with an anti-reflective coating to minimize glare and enhance readability. This crystal features a domed profile, replicating the aesthetic of the original 1967 model's plexiglass crystal. Integral to its function as a diver's instrument is the unidirectional rotating bezel, a DOXA patented design. This bezel incorporates a dual scale indicating elapsed dive time in minutes and depth in meters, facilitating the calculation of no-decompression stop limits during ascent. Attachment to the wrist is accommodated by a lug width of 20.00 mm, allowing for either the stainless steel "Beads of Rice" bracelet, equipped with a folding clasp and integrated wetsuit extension, or an FKM rubber strap featuring a folding clasp with a ratcheting wetsuit extension mechanism for precise adjustment over dive suit material. The dial maintains the iconic Searambler aesthetic.
