Wear a smartwatch with your Rolex

In short Smartlet One is compatible with all current Rolex models. The Submariner, GMT-Master II, Datejust, Daytona, and Explorer all use 19mm to 21mm lug widths, natively supported with no adapter. Installation uses the standard spring-bar system - no modification to the watch, fully reversible in seconds.

Rolex is the most recognised name in mechanical watchmaking. The Submariner, Datejust, and GMT-Master II are worn by people who expect precision from every instrument on their wrist. Smartlet One replaces the Rolex bracelet or strap via the same spring-bar mechanism Rolex uses for its own bracelet changes. The Oyster case, the crown, and the movement remain entirely untouched. All smartwatch sensors remain fully operational.

Questions

Frequently asked questions

  • Does Smartlet work with Rolex watches?
    Yes. All men's Rolex references use 20mm or 21mm lug widths, natively supported by Smartlet One. No adapter required.
  • Will Smartlet damage my Rolex?
    No. Smartlet uses the same spring-bar slots used for bracelet swaps. The Oyster case, crown seals, and movement are completely untouched.
  • Which Rolex models are covered?
    Submariner, Daytona, GMT-Master II, Datejust 41, Explorer, Sky-Dweller, Yacht-Master, Air-King, Sea-Dweller, Oyster Perpetual and more - 530+ references total.
  • Which recent Rolex releases work with Smartlet?
    At Watches and Wonders 2026, Rolex marked 100 years of the Oyster case with 58 new references, including a two-tone Oyster Perpetual 41, a Rolesium Cosmograph Daytona with a grand feu enamel dial, a redesigned Yacht-Master II powered by the new calibre 4162, and a Day-Date 40 in the new Jubilee gold alloy. The 2025 Land-Dweller introduced the Dynapulse escapement, though it uses an integrated bracelet rather than spring bars. As always, any reference with standard spring bars between 18mm and 24mm lug width works with Smartlet.
  • 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.
