Doxa Sub 750T Aquamarine 825.10.241.10

The DOXA SUB 750T Aquamarine 825.10.241.10 is a robust professional dive watch that brings a fresh, maritime-inspired twist to DOXA’s legendary SUB line. Built around a 45 mm stainless steel cushion case with a refined profile (~11.95 mm thick), it pairs serious build quality with bold visual presence. Its standout aquamarine blue dial offers high-contrast legibility with Super-LumiNova-coated hands and markers, a practical date window at 3 o’clock, and a classic unidirectional rotating bezel—complete with DOXA’s signature diver no-decompression scale—for reliably timing depth and safety stops. A flat sapphire crystal and screw-down crown complete the design, while the iconic “beads of rice” stainless steel bracelet with ratcheting wetsuit extension ties heritage styling to real-world functionality.

Underneath this striking exterior beats a Swiss automatic movement (typically a Sellita-based calibre) offering dependable performance and about 56 hours of power reserve for confident everyday use. The SUB 750T is water resistant to 750 meters (75 ATM / 2,460 ft)—a depth rating that positions it well beyond recreational dive requirements and into the realm of true professional tool watches. Whether worn on deck, at sea, or casually on land, the Aquamarine’s blend of vibrant style, robust engineering, and dive-ready capability keeps it squarely in DOXA’s tradition of purposeful, character-rich timepieces.

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.
