Wear a smartwatch with your Blancpain

In short Smartlet One is compatible with all Blancpain Fifty Fathoms and Villeret references using 20mm to 23mm lug widths, natively supported with no adapter. Installation uses the standard spring-bar system - no modification to the watch, fully reversible in seconds.

Blancpain made the Fifty Fathoms before anyone else made a dive watch worth naming. The 1953 reference set the conventions the industry spent decades following. The 45mm case, the unidirectional bezel, the liquid-proof crown - all designed for function, none for fashion. Collectors who own Fifty Fathoms references do not need convincing that both precision and data matter. Smartlet One attaches via the same spring bars Blancpain uses for bracelet changes. The watch is not modified.

Wear yours How it works
The problem
Choosing between health data and horological heritage every morning.
The solution
Smartlet One replaces your Blancpain's strap via the standard spring-bar system and positions your smartwatch on the same wrist. Both watches run simultaneously, with no modification to the watch and full reversibility in seconds.
