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.
Mizuki

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.

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.
