As an airline pilot, I am always on the run. Smartlet gives me the ability to wander across the world with my mechanical watches, while enjoying the benefits of technology. I am a fan.

First, I want to applaud the team for taking what appears to be a simple idea and realizing it at such a high level. Smartlet was worth the wait, and perhaps precisely because we waited, the product reached such an impressive level of refinement.

Tokyo, Japan

I am highly satisfied with the performance and design. I honestly expected greater restriction or discomfort given its function, but the daily wear has been surprisingly smooth. Furthermore, the look and finish of the strap itself are excellent.

FAQ

Questions about Smartlet One

What is Smartlet One?

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.

Which watches are compatible with Smartlet One?

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.

How is Smartlet different from a regular watch strap?

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.
