Doxa Sub 300β Searambler 830.10.021.10

An adventurous spirit with modern embellishments In 1968, DOXA launched the SUB 300T Conquistador, the first general public diver's watch equipped with a helium release valve. 50 years later, the SUB 300β sports watch combines DOXA's pioneering functionality with style, maintaining foundational tool watch features in a redesigned 42.5 mm diameter case, now slimmer at 11.95 mm. The black ceramic bezel and screw-down crown enhance its sport-chic character, complemented by a sophisticated sunburst dial finish. Available with an FKM rubber strap or stainless-steel "Beads of Rice" bracelet, both featuring a ratcheting folding clasp, the watch is water-resistant up to 300 meters. With a scratch-resistant sapphire crystal, Swiss automatic movement, and a power reserve of around 38 hours, the SUB 300β is engineered for safety and exploration.
