The SUB 300 was also the first of its kind to feature a unidirectional bezel incorporating the US Navy no-decompression dive table into two separate scales on the bezel, one for the outer "depth" ring and the other for the inner "time" ring, a DOXA patent.
The watch quickly became a legend in the diving world. Another legend, Commander Jacques-Yves Cousteau – the most famous undersea explorer of modern times as well as co-inventor of the Aqua Lung underwater breathing apparatus and father of modern scuba diving – was so fond of the SUB 300 that he secured exclusive distribution rights in the United States for his company, US Divers.

The new SUB 300 model comes in 42.50 mm x 45.00 mm x 13.40 mm stainless steel case with a screw-down crown and a screw-in solid case back engraved with a sailing boat. Water resistance is guaranteed up to a pressure of 30 ATM (300 metres / 984 feet).
The dial is well protected by a scratch-resistant sapphire crystal, treated with an antireflective coating, that echoes the domed plexiglass of the first SUB generations.
All dive-related markings have a Super-LumiNova luminescent coating to ensure optimum readability during dives under low visibility conditions. The indices are clearly visible, as is the dual indication of dive time and depth - expressed in minutes and meters respectively - on the patented unidirectional rotating bezel for calculating and monitoring no-decompression dive times.
