The DOXA SUB 300T Professional pays homage to its legendary predecessor, the SUB 300T Conquistador, by integrating vintage style with cutting-edge features. Crafted from 316L stainless steel, its 42.5mm x 44.5 mm case is built to withstand the pressures of the deep sea, offering a water resistance of 1,200m. The sapphire crystal, with an anti-reflective coating, ensures clarity even in the most challenging environments. Driven by a Swiss mechanical automatic movement, the watch delivers precise timekeeping with a 38-hour power reserve.

For underwater enthusiasts, the SUB 300T Professional is equipped with a screw-down crown and case back to ensure maximum water resistance and protection against moisture. The unidirectional rotating bezel facilitates precise dive time tracking. Enhanced with Super-LumiNova luminescent inserts, the bezel guarantees legibility in low-light conditions, crucial for underwater expeditions. The watch incorporates a helium release valve, a vital component for saturation diving, enabling the safe expulsion of trapped gas during ascent.

With its blend of vintage-inspired aesthetics and contemporary engineering, the SUB 300T Professional serves as a reliable companion for both seasoned divers and watch enthusiasts alike. It captures the essence of exploration and adventure while embodying DOXA's rich heritage and unwavering dedication to excellence.
