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 new SUB 300T presented in September 2019 pays tribute to the groundbreaking original.\nThis 3-hand diver's watch, available in 8 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?LumiNova® luminescent insert to ensure optimal legibility underwater. The bracelet is 316L stainless steel and features a folding clasp with the DOXA fish symbol.\n\nTechnical data\nMOVEMENT\nSwiss mechanical automatic, self-winding\nPower reserve 38 hours\nFrequency 28,800 vph (4.0 Hz)\nDecorated by DOXA\nCASE\nStainless steel case\nDiameter 42.50 mm x 44.50 mm\nHeight 13.65 mm\nScrew-down crown\nWater resistance 120 ATM / 1,200 meters / 3,937 feet\nStainless steel, screw down case back\nINDICATIONS\nHours, minutes, seconds, Date\nFEATURES\nSapphire crystal\nUnidirectional rotating bezel (in feet)\nHelium release valve\nBRACELET / STRAP\nFKM rubber strap, folding clasp with ratcheting wetsuit extension\nLug width 20.00 mm\nDIAL\nIconic dial
