The Doxa SUB 300T represents a pivotal chapter in dive watch history, originally launched in 1967 as part of Doxa's pioneering collaboration with diving legend Jacques Cousteau and his Calypso team. This reference established Doxa's reputation as a serious tool watch manufacturer for professional divers, with its distinctive orange dial becoming synonymous with underwater exploration during the golden age of dive watch development. The SUB 300T earned its credentials through real-world use by commercial and military divers, cementing its place alongside other iconic dive watches of the era as an authentic professional instrument rather than merely a sporting timepiece.

The SUB 300T is powered by the robust ETA 2824-2 automatic movement, a Swiss-made caliber renowned for its reliability and serviceability among collectors and professionals alike. The 25-jewel movement operates at 28,800 vibrations per hour with a power reserve of approximately 38 hours, housed within a substantial 42.5mm stainless steel case rated to 300 meters water resistance. The watch features a unidirectional rotating timing bezel with distinctive minute markings, while the case construction includes a screw-down crown and caseback to maintain its professional diving credentials.

Design-wise, the SUB 300T showcases Doxa's signature aesthetic elements, most notably the vibrant orange "Professional" dial that has become the brand's calling card among dive watch enthusiasts. The dial features applied hour markers with tritium or Super-LumiNova luminous material, complemented by the iconic Mercedes-style hands that ensure optimal legibility in low-light conditions. From a collectibility standpoint, the SUB 300T occupies a unique position in the vintage dive watch market, appealing to collectors who appreciate its authentic professional heritage and distinctive visual identity. Modern reissues have maintained the original's core design DNA while introducing contemporary manufacturing techniques, making both vintage examples and recent productions highly sought after by enthusiasts who value the reference's historical significance and unmistakable character within the dive watch genre.
