In 1967, DOXA launched the revolutionary SUB concept, considered to be the first truly purpose-designed diver’s watch for a broad audience. The radical innovations it introduced at the time quickly made it the benchmark for professionals, too. Rated to a depth of 300 meters (30 ATM), it was the first of its kind to feature a unidirectional bezel with dual markings for dive times and depths for calculating and monitoring no-decompression dives.

At the time, the US Navy no-decompression dive table was the be-all and end-all, enabling divers to first determine and then monitor the time they could remain at a predetermined depth and still ensure a safe return to the surface – without having to make a decompression stop on the way back up. DOXA engineers took the US Navy’s calculations and incorporated them into two separate scales on the bezel, one orange for the outer “depth” ring and the other black for the inner “time” ring – a DOXA patent.

The first to feature a bright orange dial, in daring contrast to the conventional black or white diver’s watches of the day, the instantly recognizable SUB 300 soon became a legend in its own time.

Starting 1968, the SUB 300 became easy to spot on the wrists of divers jumping from the deck of the Calypso every week to take millions of TV viewers on the thrilling missions of “The Undersea World of Jacques Cousteau” Team Undersea Odyssey”. Already a living legend back then, Commander Jacques-Yves Cousteau – co-inventor of the Aqua Lung underwater breathing apparatus and spiritual father of modern scuba diving – was so fond of the SUB 300 that he secured exclusive distribution rights in the United States for his company, US Divers.

From 2015, the SUB 300 is available as a limited edition in only three dial colors with orange, black and silver. For the brand’s 130th Anniversary, DOXA Watches is launching the DOXA SUB 300 in 6 colors and 12 versions, all vibrant, bright, full of summer zest and ready for adventure. Not to forget the iconic “beads of rice” bracelet, also made of stainless steel.

DOXA Watches introduces rubber straps in colors for a tone-on-tone match with the dials, a first for its collections and a sporty alternative to the steel bracelet. Made from soft and supple rubber, these new straps come with the DOXA hallmarks on both sides and provide an amazingly comfortable fit.
