DOXA SUB 300T Conquistador

A new interpretation of the DOXA SUB 300T Conquistador

Reading Time: 2 minutes

In Swiss watchmaking, you will still find brands that are steeped in a rich and fascinating history and that quietly live up to a relentless pursuit of excellence. DOXA is a prime example. In 1969, DOXA unveiled the SUB 300T Conquistador. Reliable, efficient and affordable, it was at the time the first diver’s watch to come equipped with a helium release valve, a unidirectional rotating bezel for setting no decompression dive times, and an orange dial for exceptional underwater legibility. Developed for the general public and the growing number of underwater diving enthusiasts, the SUB 300T Conquistador already then set the benchmark for what a purpose-designed diver’s watch should be. Today, 50 years later, the new SUB 300T Conquistador pays tribute to this historic model. It is a testament to the enduring appeal of the DOXA SUB concept and the unshakeable loyalty it enjoys among professional and recreational divers the world over.

2019: The SUB 300T Conquistador comes in a choice 6 dial colours

The legend returns with a choice of six original dial colours: orange, of course (Professional); yellow (Divingstar); navy blue (Caribbean); turquoise (Aquamarine); silver (Searambler); and black (Sharkhunter). Incorporating the aesthetics that unmistakably defined the SUB 300T Conquistador, the famous three-handed diver’s watch also brings together all the technical aspects that make it the true to purpose, reliable and desirable diving watch for today.DOXA SUB 300T Conquistador

Fabricated from 316L stainless steel of the highest quality, the DOXA SUB 300T Conquistador’s case has a diameter of 42.5 mm and is topped with a scratch-resistant sapphire crystal. The pressure resistance of 120 bar (1’200 meters) allows diving at very deep depths. In addition, the model naturally also features the patented unidirectional rotating bezel with dual indication of dive time in minutes and depth in feet for returning to the surface without decompression stops.

All the display elements related to diving information feature a Super-LumiNova® luminescent coating to ensure optimal legibility under low light conditions and underwater. The bracelet for this collection is made of 316L stainless steel and sports a folding clasp with the exclusive DOXA fish symbol. A rubber strap version will be available as well from mid-December 2019.
