The DOXA SUB 300T Sea Emerald is a watch that perfectly blends history, innovation, and precision craftsmanship. First introduced in 1968 as the SUB 300T Conquistador, the world's first diver's watch with a helium release valve, it became an iconic piece. Now, over 50 years later, DOXA has reimagined this classic design with the new SUB 300T, launched in September 2019, to honor its groundbreaking predecessor.

Crafted from top tier 316L stainless steel, the 42.5mm case is complemented by a scratch resistant sapphire crystal with an anti-reflective coating, ensuring both durability and clarity. Capable of withstanding pressures up to 120 bar, this extraordinary timepiece is water resistant to an impressive depth of 1,200 meters. The unidirectional rotating bezel features an integrated no decompression dive time calculator, and the Super LumiNova luminescent insert ensures excellent legibility even in the darkest underwater conditions.

With a Swiss mechanical automatic movement, a 38 hour power reserve, and a sturdy stainless steel bracelet with a folding clasp featuring the signature DOXA fish symbol, this watch is both stylish and functional. The stunning sunray dial completes the look, making the DOXA SUB 300T Sea Emerald a must have for both diving enthusiasts and those who appreciate timeless design.
