Doxa SUB 300 Carbon Aqua Lung US Divers Sharkhunter 822.70.101AQL.20 Limited

Bridging history, past and future, the SUB 300 Aqua Lung US Divers pushes the envelope and marks a first with a forged carbon case and black rubber strap. A limited series of only 300 timepieces with COSC-certified caliber, in partnership with Aqua Lung.

Jet black alternating with shades of charcoal: Forged carbon gives the SUB 300 Carbon Aqua Lung US Divers an urban camouflage vibe. The ultra-lightweight high-tech material of the case and dial has a matte, raw look and feel that accentuates a sense of vibrant energy and toughness of purpose.

With a diameter of 42.5 mm, the SUB 300 carbon Aqua Lung US Divers is fitted with a pressure-resistant titanium chamber to protect the movement and a screw-down crown. This watch is rated to a depth of 300 meters, allowing maximum freedom of undersea exploration. Its scratch-resistant sapphire crystal, treated with an antireflective coating, echoes the domed plexiglass of early SUB generations. The COSC-certified automatic movement ensures a power reserve of 38 hours.

All dive-related information is highlighted with a Super-LumiNova® luminescent coating to ensure excellent legibility in reduced visibility conditions. The black soft rubber strap with a black PVD steel folding clasp featuring the exclusive “DOXA fish” symbol completes this stunning watch.

DOXA, founded in 1889 by Georges Ducommun in Le Locle, Switzerland, has a rich history of watchmaking innovation. Initially gaining recognition for its pocket watches and dashboard clocks, DOXA's defining moment came in 1967 with the introduction of the SUB 300 dive watch. This groundbreaking timepiece, featuring an iconic orange dial, unique no-decompression bezel, and purpose-built design for recreational divers, quickly became a benchmark in the industry. Notably, in collaboration with Rolex and the introduction of the Sea-Dweller, DOXA co-developed the now-common helium escape valve concept, adding another feather in its cap as a true diver’s tool in its day. DOXA's reputation was further enhanced by its association with Jacques-Yves Cousteau and its frequent appearance in Clive Cussler's adventure novels.

Despite facing challenges during the quartz crisis, DOXA experienced a resurgence after its acquisition by the Jenny family in 1997. Today, the brand continues to honor its diving heritage while embracing modern watchmaking techniques. DOXA's journey from a small Swiss workshop to a globally recognized dive watch manufacturer demonstrates its enduring commitment to innovation, quality, and functionality. The brand's iconic designs, particularly the SUB series, remain popular among diving enthusiasts and watch collectors alike, cementing DOXA's place in horological history.
