Few Swiss watch brands carry as much authentic diving heritage as Doxa — a maison founded in Le Locle in 1889 that produced one of the world’s first purpose-built diving watches in 1967. The Sub, with its unmistakable orange dial and nitrogen narcosis depth-warning scale, became the instrument of choice for Jacques Cousteau’s diving team and has since achieved cult status among serious collectors worldwide. The Doxa men’s collection honours this remarkable legacy while embracing contemporary finishing standards and modern movement technology. Cases are constructed from polished and satin-brushed stainless steel, engineered to withstand the considerable pressures of professional diving — water resistance ratings of 300 to 1,200 metres are standard across the Sub family — and complemented by unidirectional rotating bezels with ceramic or aluminium inserts for precise elapsed-time measurement. Swiss automatic movements, often sourced from ETA and Sellita, drive the hands with dependable mechanical accuracy, while exhibition casebacks allow collectors to appreciate the rotor and escapement in motion. Dial colours — the iconic orange, professional black, aquamarine, and classic silver — give each Sub variant a distinct character without departing from the brand’s utilitarian philosophy. Beyond the Sub, Doxa’s dress and sport collections demonstrate remarkable versatility.
