Wear a Smartwatch with Your Doxa | Smartlet

Smartlet One is compatible with all Doxa SUB 200, SUB 300, and SUB 600T references using 20mm lug width, natively supported with no adapter. Installation uses the standard spring-bar system - no modification to the watch, fully reversible in seconds.

Doxa made the SUB in 1967 and created the professional dive watch colour language. The orange dial was visibility. The graduated unidirectional bezel was survival. Jacques Cousteau wore one. The watch became a cult object not through marketing but through use. Today the SUB 300 carries the same dimensions, the same intent. Smartlet One attaches via the spring-bar system - the same mechanism used for every strap change the SUB has seen in sixty years.
