Questions

Frequently asked questions

  • Which Black Bay references are compatible with Smartlet?
    All Tudor Black Bay references are compatible. The Black Bay 41 uses 22mm, the Black Bay 36, Fifty-Eight, GMT, and Pro use 20mm, and some earlier or smaller references use 18mm. All are within Smartlet's supported 18-24mm range.
  • Does the Black Bay 41's 22mm lug width need a special adapter?
    No. Smartlet's Universal Fit Kit covers 18-24mm lug widths. The Black Bay 41's 22mm is natively supported without any additional accessory beyond the standard Smartlet box.
  • Will Smartlet affect the Black Bay's water resistance?
    Smartlet replaces the strap only and has no contact with the case or crown seals. The Black Bay's 200m water resistance rating is determined by the case and crown, both of which remain completely untouched by 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.
