SUB 300


SKU: 821.10.351.10

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 orange 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.

Starting 2020, the SUB 300 will be available in 6 colors. It can be specified either with the iconic ‘beads of rice’ stainless steel bracelet or a sporty rubber strap, with distinctive DOXA cues on both sides, to match the color of the dial. The folding clasp of the rubber strap features the exclusive DOXA fish symbol and has an adjustable diving extension to accommodate the thickness of a wetsuit. The folding clasp of the beads of rice bracelet is equipped with a wetsuit extension.
