SUB 300T SHARKHUNTER
In 1968, DOXA launched the SUB 300T Conquistador, the first general public diver's watch equipped with a helium release valve. 50 years later, the new SUB 300T presented in September 2019 pays tribute to the groundbreaking original.
This 3-hand diver's watch, available in 8 dial colors, combines the aesthetic genes of the SUB 300T Conquistador with the technical refinements that define the high-performance diver's watch of today. Constructed from 316L stainless steel of the highest quality, the SUB 300T has a diameter of 42.5mm and a scratch-resistant sapphire crystal with an anti-reflective coating. Rated to withstand pressures up to 120 bar, this diver is effectively waterproof to a depth of 1,200 meters and features the patented unidirectional rotating bezel with an integrated no-decompression dive time calculator. All elements providing dive-relevant information are highlighted with a Super‑LumiNova® luminescent insert to ensure optimal legibility underwater. The bracelet is 316L stainless steel and features a folding clasp with the DOXA fish symbol.

DOXA Diving Watches
Since its founding in 1889 by Georges Ducommun in the heart of Le Locle, DOXA has carved out a distinctive place in Swiss watchmaking—defined by innovation, precision, and purpose-driven design. From its earliest achievements, the brand demonstrated a forward-thinking approach, most notably with the patented 8-Day DOXA calibre in 1907. This breakthrough didn’t just elevate watchmaking standards—it found its way into the dashboards of Bugatti racing cars, before becoming a trusted instrument across automotive, aviation, and maritime industries.
