FAQ
Smartlet One is a patented modular watch strap engineered to fit any metal watch with a lug width between 18mm and 24mm - the widest compatibility range on the market. It lets you wear a mechanical watch and a smartwatch simultaneously on the same wrist, with no modification and no tools.
Smartlet One is compatible with any metal watch using a standard lug width between 18mm and 24mm. Full compatibility guides are available for Rolex, Omega, Tudor, Breitling, IWC, Seiko, TAG Heuer, Panerai, Jaeger-LeCoultre, Blancpain and over 100 other compatible brands. For smartwatches, it supports Apple Watch (all series), Samsung Galaxy Watch, Garmin Fenix, Garmin Forerunner, Polar Vantage, Whoop, and more.
Before Smartlet, you needed one strap per watch. Smartlet One reverses that logic: one strap for any combination. Two mechanical watches, two smartwatches, or one of each - you choose. A patented dual-carrier system compatible with 18mm to 24mm lug widths, switching in 3 seconds with no tools. The only patented product in this category, awarded at Concours Lépine 2025 and selected for CES 2026.
