When two names that have written diving history meet, the result can only be extraordinary.

This special edition represents an evolution of the iconic SUB 300, reinterpreted with high-tech materials, an even more sophisticated construction, and a production limited to only 300 pieces. A watch designed for those who consider the sea not just a passion, but a way of life.

The meeting of two diving legends

The name Aqua Lung holds a special place in the history of underwater exploration.

The company, closely linked to the legacy of Jacques-Yves Cousteau and the spread of modern diving equipment, has shared the same philosophy as DOXA for decades: developing reliable instruments for those who experience the sea firsthand.

The SUB 300 Carbon Aqua Lung US Divers pays homage to this historic collaboration, reinterpreting one of the brand's most iconic divers through a contemporary language that retains the original model's DNA intact.

Forged carbon: lightness and character

The main innovation of this model is the forged carbon case.

This high-performance material guarantees an extremely low weight compared to traditional steel, while offering high resistance to impact and corrosion. Each case features a unique and unrepeatable texture, creating a visual effect that makes each piece slightly different from the others.

The dial also uses forged carbon, with shades ranging from deep black to anthracite, giving a technical and contemporary look that immediately stands out.

Titanium and robustness for diving

Behind the lightness of carbon lies a structure designed to withstand the most demanding conditions.

Inside the case is a titanium inner chamber, designed to protect the movement from high pressures during diving. The screw-down crown, titanium case back, and water resistance up to 300 meters (30 ATM) confirm the professional vocation of the SUB 300 Carbon Aqua Lung US Divers.

The domed sapphire crystal with anti-reflective treatment also recalls the profile of the first historical SUB 300s, creating a perfect balance between heritage and innovation.

COSC certified precision

The watch is powered by a Swiss Made automatic movement COSC Chronometer certified.

The certification issued by the Contrôle Officiel Suisse des Chronomètres guarantees compliance with rigorous precision standards, offering a higher performance level compared to common automatic movements.

The power reserve exceeds 38 hours, while the frequency of 28,800 vibrations/hour ensures regular and reliable operation even during intensive use.

Everything you need underwater

Like every true DOXA, this special edition also retains the elements that have made the brand famous among professional divers and enthusiasts.

The unidirectional rotating bezel with decompression scale, the indexes and hands coated with Super-LumiNova®, the FKM rubber strap with folding clasp and wetsuit extension are designed to ensure maximum functionality even during the most demanding dives.

Every detail is designed to offer legibility, comfort, and safety in all conditions.

A limited edition for collectors

With a production limited to 300 pieces, the DOXA SUB 300 Carbon Aqua Lung US Divers COSC represents one of the most exclusive interpretations of the iconic Swiss diver.

The use of forged carbon, the COSC certification, the collaboration with Aqua Lung, and the strong appeal to diving history transform this model into a timepiece that goes beyond the simple function of a dive watch.

It is a creation dedicated to those who wish to wear an authentic professional instrument, made with avant-garde materials and inspired by two brands that have contributed to changing the world of underwater exploration.
