Doxa SUB 300T Conquistador Watch Review
Doxa SUB 300T Conquistador

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.
