The Doxa SUB 300 Caribbean 821.10.201.10 is the steel-bracelet, turquoise-dial version of the dive watch that in 1967 introduced the bidirectional no-decompression bezel scale. It has a 42.5mm cushion case in 316L steel, a COSC-certified automatic chronometer movement, and 300m water resistance. Cazador has no verified price observations (n=0) for this reference as of today.

Doxa was founded in 1889 in Le Locle, Switzerland, but its defining moment as a dive-watch brand came in 1967 with the original SUB 300, developed alongside pioneering American recreational diving figures close to Jacques Cousteau's circle and U.S. Divers. It was among the first watches designed specifically for civilian, recreational diving rather than purely professional or military use, with a unidirectional bezel that let divers calculate no-decompression times directly on the wrist.
The cushion-shaped case with rounded square corners, now 42.5mm in 316L steel, is one of vintage dive watches' most recognizable visual signatures, and has remained largely unchanged across successive SUB 300 reissues.
The 'Caribbean' colorway, with its signature turquoise dial, belongs to the color palette Doxa historically associates with different depths and diving conditions — a tradition the brand revived in the modern SUB 300 reissue starting in 2020 [UNVERIFIED: exact launch year for this specific steel-bracelet configuration].
This reference runs a Swiss automatic movement certified as a chronometer by COSC, with 38 hours of power reserve and 300 meters of water resistance, paired with the bidirectional dive bezel [UNVERIFIED: the exact base caliber is not confirmed in this entry].
