Following in the spirit of the SUB 300T Conquistador introduced in 1969, the first general public diving watch to meet the pressure challenge with the helium release valve, the SUB 1500T proves a worthy successor – an authentic diver\'s watch built to withstand the toughest of challenges. Its cushion-shaped case is made of 316L stainless steel of the highest quality. With a diameter of 45 mm, the SUB 1500T is rated at 150 ATM for dives at depths up to 1, 500 meters. Paying tribute to the SUB 300T Conquistador, it features the same patented unidirectional rotating bezel and integrated helium relief valve as its legendary predecessor. All the elements that provide dive mission-critical information are equipped with a Super-Lumi Nova® luminescent coating to ensure optimum legibility underwater. The bracelet is 316L stainless steel and features a folding clasp with the DOXA fish symbol.
