Both watches sit on the same wrist. The smartwatch sits underneath, against the skin; readings taken there are not certified by its manufacturer.

Questions

Frequently asked questions

  • Does Smartlet work with all Rolex Daytona references?
    References with 19mm / 20mm lug widths are covered, with watch adapters in the matching width. The Daytona model guide lists every reference, vintage included.
  • Will the Apple Watch sensors work on the inner wrist?
    The sensors face the skin underneath the wrist, and the bracelet is sized by its links so the Apple Watch sits snug. Apple does not certify readings taken in this position: for a reading with medical weight, put the Apple Watch back on its own band and follow Apple's instructions. Notifications and the other functions work as usual.
  • Does Smartlet affect the Daytona's chronograph?
    No. The watch adapters seat in the Daytona's lug holes in place of the spring bars. The case, pushers and movement are untouched, and the change is fully reversible.
  • Does Smartlet damage or modify my mechanical watch?
    No. The watch adapters seat in your watch's lug holes in place of the spring bars. Nothing is modified on the case, lugs or dial, and the change is fully reversible: your mechanical watch can go back on its original strap at any time.
