Details

In 1967, DOXA launched the revolutionary SUB concept, considered to be the first truly purpose-designed diver’s watch accessible to a broader public. The radical innovations it introduced at the time soon made it the benchmark for professionals, too. Water- resistant to 30 bar, roughly equivalent to a depth of 300 meters, it was the first to feature a unidirectional bezel with a dual scale for depth and dive time to calculate a safe ascent without decompression stops. Most radical of all: the silver dial which greatly improved readability underwater. The SUB 300’s 42.5 mm case is made from the highest quality 316L stainless steel. The three-hand self-winding movement holds the prestigious COSC Certified Chronometer certification guaranteeing precision, robustness and reliability. It also provides a 38-hour power reserve. The date window is positioned at 3 o'clock. The SUB 300 naturally features the famous unidirectional rotating bezel, a DOXA patent, with the dual indication of dive time in minutes and depth in meters for calculating no-stop decompression dive times. Featuring a screw-down crown, its water-resistance is rated to 300 meters, or approximately 980 feet. As a nod to its heritage, today’s SUB 300 is topped with a scratch-resistant sapphire crystal with an anti-reflective treatment. It has 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.
