DOXA is still innovating and breaking watch traditions with their latest release - the new SUB 300 Aqua Lung US Divers watch.

After more than 130 years of watchmaking tradition, DOXA is still innovating and breaking watch traditions with the new SUB 300 Aqua Lung US Divers watch - a timepiece that builds a bridge between the past and the future.

It is the first time the SUB 300 comes in carbon, and is the result of a partnership that reconnects two legendary brands: DOXA x Aqua Lung.

The new model

The SUB 300 Carbon Aqua Lung US Divers builds on its origins while cultivating an

edgier, more technical but also a more urban look. A limited series of 300 pieces, each an officially COSC Certified Chronometer designed with precision, robustness, reliability. All the self-winding mechanical movements that power the 300 units of the SUB 300 Carbon Aqua Lung US Divers edition are certified by the prestigious COSC (“Contrôle Officiel Suisse des Chronomètres”), which guarantees the chronometric performance and scrupulous compliance with requirements in terms of precision, reliability, shock resistance, automatic winding and ease of maintenance.

Forged carbon provides DOXA with an advanced and stylistic material to build on the heritage of the SUB 300. 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 the watch more radical and contemporary. Also a distinctive feature of this limited series of only 300 pieces: the use of carbon not only for the case but also for the dial – the discretion of black contrasts with the assertive presence of white and yellow.

Far from the conventional classic black cases, the texture and colours of forged carbon are simply unique. Matte, raw, high-tech, the material seems both very compact and irregular. This very particular non-homogeneous pattern, achieved by working with randomly oriented carbon fibers, creates a subtle balance between the deference to its roots and the indomitable drive to break new ground – just as the SUB 300 did way back then.

All dive-related markings have a Super-LumiNova® luminescent coating to ensure optimum readability during dives under low visibility conditions. The white indices are clearly visible, as is the dual indication of dive time in minutes and depth in feet on the famous patented 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 bezel are yellow for visual differentiation, with a yellow dot at 12 o'clock.

History of the SUB 300

In 1967, DOXA launched the revolutionary SUB concept with the SUB 300. Rated to 30 ATM, (water resistance to a depth of 300 meters), it marked a 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. The watch soon also becomes easily recognisable because of its bright orange sub-dial, different from anything else on the market at the time.

Since then, DOXA has continuously perfected its diver's watches, and in particular the most emblematic of all, the SUB 300, which remains one of the rare diver's watches to have made its mark in Swiss watchmaking history. The legend lives on.

More than 50 years after its launch, true to its unique tradition of innovation, the legendary 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: the brand that embraced the SUB concept in the early days, through an official partnership that has just been signed to coincide with this product premiere. The SUB 300 Aqua Lung US Divers – a bridge from the past to the future.
