In 1969, DOXA launched the SUB 300T Conquistador, the first general public diver\'s watch equipped with a helium release valve. 50 years later, the new SUB 300T presented in September 2019 pays tribute to the groundbreaking original. This 3-hand diver\'s watch, available in 6 dial colors, combines the aesthetic genes of the SUB 300T Conquistador with the technical refinements that define the high-performance diver\'s watch of today. Constructed from 316L stainless steel of the highest quality, the SUB 300T has a diameter of 42. 5mm and a scratch-resistant sapphire crystal with an anti-reflective coating. Rated to withstand pressures up to 120 bar, this diver is effectively waterproof to a depth of 1, 200 meters and features the patented unidirectional rotating bezel with an integrated no-decompression dive time calculator. All elements providing dive-relevant information are highlighted with a Super-Lumi Nova® luminescent insert to ensure optimal legibility underwater. The bracelet is 316L stainless steel and features a folding clasp with the DOXA fish symbol.
