The SUB 300β sports watch combines 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. True to DOXA's unconventional ethos, it blends the spirit of the times with an elegant, modern sport-chic look suitable for urban settings.
