Doxa professional diving watch, SUB 300 model that was first launched in 1967 and quickly became a reference point for professional divers. It has a water resistance of up to 30 bar and was the first watch to offer a unidirectional bezel with double depth scale and dive time for a safe ascent. Finally, the color of the dial has improved its legibility in the water.

The SUB 300 case is 42.5mm and is made of 316L stainless steel with COSC certification. Its power reserve is 38 hours. As previously mentioned, the dial is orange with the date window positioned at 3 o'clock.
