Originally released in 1969, the Doxa SUB300T Conquistador was the first dive watch with a helium release valve available to the general public. This year, the watch is being brought back to the lineup with those same classic looks and six different dial colors. The watch features a stainless steel 42.5mm case with a waterproof rating of 1,200 meters/4,000 feet. It also boasts an ETA 2824-2 automatic movement with a 42-hour power reserve and a "Beads of Rice" style stainless steel bracelet.
