In 1967, DOXA launched the revolutionary SUB concept, considered to be the first truly purpose-designed diver's watch accessible to a broader public. Taking inspiration from this truly radical innovation of 1967, discover the DOXA SUB 300 Sharkhunter 821.10.101.10 at Chisholm Hunter today. Water-resistant to 300 metres, this model features a unidirectional bezel with a dual scale for depth and dive time to calculate a safe ascent without decompression stops. With a 42.5 mm case crafted from the highest quality 316L stainless steel, the 3-hand self-winding movement provides a 38-hour power reserve. Today's SUB 300 black dial is protected by scratch-resistant sapphire crystal with an anti-reflective treatment and the same domed shape as the plexiglass on the 1967 original. All dive-related markings feature a Super-LumiNova® luminescent coating to ensure excellent readability in low-visibility conditions. Presented on the iconic 'Beads of Rice' stainless steel bracelet with folding clasp
