Doxa Watch Sub 300T Divingstar Bracelet 840.10.361.10. In 1969, DOXA launched the SUB 300T Conquistador, the first general public divers watch equipped with a helium release valve. 50 years later, the new SUB 300T presented in 2019 pays tribute to the groundbreaking original. This 3 hand divers watch, available in 6 dial colors, combines the aesthetic genes of the SUB 300T Conquistador with the technical refinements that define the high performance divers 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 1200 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.
