In 1968, doxa launched the sub 300T Conquistador, the first consumer diving watch equipped with a helium valve. 50 years later, the new sub 300T presented in September 2019 pays tribute to the revolutionary character of the original. This 3-hand diver's watch, available in 8 dial colors, combines the aesthetic codes of the sub 300T Conquistador with the technical features that define today's high-performance diver's watch. Constructed from the highest-quality 316L stainless steel, the sub 300T has a diameter of 42.5 mm and a scratch-resistant sapphire crystal with anti-reflective treatment. Designed to effectively withstand pressures of up to 120 bar, this diver's watch is water-resistant to a depth of 1,200 meters and features a patented unidirectional rotating bezel with integrated no-decompression dive time calculator. All elements providing diving-relevant information are highlighted by a Super-LumiNova luminescent insert to ensure optimal underwater legibility. The 316L stainless steel bracelet features a folding clasp with the "doxa fish" symbol.
