The Doxa SUB 300 professional diving watch was first launched in 1967 and quickly became a benchmark for professional divers. It offers water resistance up to 30 bar and was the first watch to feature a unidirectional bezel with a dual scale for depth and dive time, ensuring a safe ascent. Additionally, the dial color enhances readability underwater.

The SUB 300 case measures 42.5 mm and is crafted from 316L stainless steel with COSC certification. Its power reserve is 38 hours, and, as mentioned, the dial is silver with a date window positioned at 3 o’clock.

The sapphire crystal is shock- and scratch-resistant with an anti-reflective coating. The indexes are treated with Super-Luminova for excellent readability in low-light conditions.
