Questions

Frequently asked questions

  • Which Black Bay references are compatible with Smartlet?
    Most Tudor Black Bay models use 19 to 22 mm lug widths depending on the reference: the Black Bay 58 and 54 use 20 mm, the current Black Bay 41 uses 21 mm and older 41 mm references 22 mm, and the Black Bay 36 uses 19 mm, all within Smartlet's 18 to 24 mm range. The Black Bay 32 uses 16 mm, below 18 mm, and is not compatible.
  • Does the Black Bay 41 need a special part?
    No. You choose the watch adapter width at order: 21 mm for the current Black Bay 41, 22 mm for older references. The watch adapters seat in the lug holes in place of the spring bars.
  • 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. 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.
