A fusion of vintage and modern, built for any adventure 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 6 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.

All elements providing dive-relevant information are highlighted with a Super‑LumiNova® luminescent insert to ensure optimal legibility underwater.
