Smartlet One
Un concept. Trois personnalités différentes.
Wear a Smartwatch with Your Blancpain
Brand compatibility guide
Blancpain
Wear a smartwatch
with your Blancpain
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.

Comment ça marche
Three steps to both watches on one wrist
01
Choose your strap
Smartlet One is your new strap. It replaces the original bracelet or strap on your Rolex using the same spring-bar system. Lug widths 20mm / 21mm are all natively supported.
02
Clip in your watch
Attach the Smartlet strap to your Rolex by fitting the spring bars into the lugs, exactly as with any standard strap change. No tools required. Fully reversible in seconds.
03
Clip in your smartwatch
Slide your smartwatch into the Smartlet module. It locks onto the strap module on the wrist side of your wrist. All sensors remain fully operational. Both watches run simultaneously.
