Wear a smartwatch with your Cartier Tank

In short Smartlet is compatible with the Cartier Tank. Lug width: 18mm / 19mm / 20mm / 21mm / 22mm - natively supported with no adapter. Installation uses the standard spring-bar system. No modification to the watch required. Fully reversible in seconds.

The Tank was designed by Louis Cartier in 1917, the case shape drawn from the caterpillar tracks of Renault tanks advancing across the Western Front. Over a century later, the parallel bars of the case remain one of the most copied forms in design history - and one of the least successfully imitated. The Tank Solo for daily precision. The Tank Américaine for the wrist that needs presence. The Tank Cintrée for those who understand why a curved case changes everything. Smartlet adds connected data without disturbing any of those choices.
