Questions

Frequently asked questions

  • Which Speedmaster references are compatible with Smartlet?
    115 Omega Speedmaster Moonwatch references in our base fit Smartlet One, on 20mm to 21mm lugs with standard spring bars. Check your exact reference in the table before you order.
  • Will Smartlet scratch the Speedmaster case?
    No. The watch adapters seat in the lug holes in place of the spring bars, and the bracelet does not touch the case, bezel or crystal.
  • Can I wind the Speedmaster while wearing it on Smartlet?
    Yes. The crown remains fully accessible. Smartlet replaces the strap only. The case, crown, and all watch functions remain completely unobstructed.
  • Does Smartlet damage or modify my mechanical watch?
