The Doxa SUB 300 is the result of a partnership that reconnects tow legendary brands: Doxa and Aqua Lung. This watch builds a bridge between the past and the future, since it is the first time the SUB 300 comes in carbon.
In 1967, Doxa launched the revolutionary SUB concept with the SUB 300, considered to be the first truly purpose-designed watch that is also accessible to the general public. The radical innovations it introduced, quickly made it the benchmark for professionals, too. Rated to 30 atm, it marked the first with a patented rotating bezel that allowed the diver to calculate and monitor no-decompression dive times based on the official US Navy dive tables. Another first was the bright orange coloured dial which contrasted strongly with the traditional black or white dials of the time. This made the DOXA Sub 300 instantly recognizable and gave it the legendary status it still holds today.
More than 50 years after its launch, the SUB 300 is now reinterpreted in carbon. The SUB 300 Aqua Lung US Divers pays tribute to a rich past while reconnecting with Aqua Lung through an official partnership.

So light compared to its stainless steel peers, the SUB 300 in forged carbon gains an urban camouflage vibe. Jet black alternating with shades of charcoal: The iridescent effect plays with reflections that change with the intensity of ambient light, making for a more radical look.
Far from the conventional classic black cases, the texture and colors of forged carbon are simply unique. Matte, raw, high-tech, the material seems both very compact and irregular. This very particular non-homogenous pattern, achieved by working with randomly oriented carbon fibers, creates a subtle balance between the deference to its roots and the need to break new ground.
Thus, the SUB 300 Carbon Aqua Lung US Divers builds on its origins while cultivating an edgier, more technical but also urban look. This is also ensured by the discretion of black contrasts with the assertive presence of white and yellow on the dial. All dive-related markings have a Super-LumiNova luminescent coating to ensure optimum readability during dives under low visibility conditions. The white indeces are clearly visible, as is the dual indication of dive time in minutes and depth in feet on the famous unidirectional rotating bezel for calculating and monitoring no-decompression dive times. The inserts of the diving scale defined by the bezel are white, with a white dot at 12 o’clock. The depth indications in feet on the outer bezel ring are yellow for visual differentiation, with a yellow dot at 12 o’clock.
The bright yellow minute hand of the Doxa SUB 300 Carbon Aqua Lung US Divers is the same yellow as the Aqua Lung logo placed at 7 o’clock.

With a diameter of 42.5 mm, the SUB 300 Carbon Aqua Lung US Divers features a pressure-resistant titanium chamber and a screw-down crown to protect the movement. This watch is water-proof up to 30 bar and is equipped with a scratch-resistant, anti-reflective sapphire crystal which echoes the domed plexiglass of early SUB generations.

Precision, robustness, reliability: All the automatic movements that power the 300 units of the SUB 300 Carbon Aqua Lung US Divers are COSC certified. This guarantees highest standards in chronometric performance and scrupulous compliance with important quality features. The calibre ETA 2824-2 works at a frequency of 4 Hz and offers a power reserve of 40 hours minimum.

The watch is fitted with a black soft rubber strap.
