About This Watch:
The DOXA SUB 300 is a modern reissue of the legendary 1967 original — the first purpose-built dive watch with a unidirectional bezel and no-decompression limits on the bezel. Jacques Cousteau's Aqua-Lung team wore DOXAs during their Conshelf underwater habitat experiments. The Sharkhunter variant features the signature black dial with orange accents, referencing DOXA's diving heritage. This example comes COSC-certified with the full kit including the branded NATO strap and travel case.
