Questions

Frequently asked questions

  • Does Smartlet work with all Rolex Submariner references?
    Yes. All current Submariner references (126610LN, 126610LV, 124060, 126619LB, 126618LB) use 20mm or 21mm lug widths, both supported by Smartlet One. Vintage references from 1953 onwards also use 20mm and are compatible.
  • Will the Apple Watch sensors work correctly on the inner wrist?
    Yes. The optical heart rate sensor, blood oxygen monitor, and ECG electrodes maintain full skin contact when mounted on the inner wrist via Smartlet. Accuracy in this position has been confirmed by Smartlet users in extended daily wear.
  • Can I remove the Apple Watch and wear my Submariner alone?
    Yes. The Apple Watch adapter detaches in seconds. You wear the Submariner on the Smartlet strap alone with no visible trace of the module. You can also reinstall the original Oyster bracelet at any time.
  • Does Smartlet damage or modify my mechanical watch?
    No. Smartlet replaces your standard watch strap using the existing spring-bar system. It makes no permanent modification to the watch case, lugs, or dial. The process is fully reversible in seconds. Your mechanical watch is unaffected and can be worn independently at any time by reinstalling its original strap. Smartlet is engineered to watchmaker tolerances and tested with the same care that goes into the watches it pairs with.
