Questions

Frequently asked questions

  • Does Smartlet work with the Datejust on a jubilee bracelet?
    Smartlet replaces the strap or bracelet entirely using the same spring-bar slots. Whether your Datejust came on an Oyster or jubilee bracelet, installation is identical. Your original bracelet can be reinstalled at any time.
  • Which Datejust references are compatible with Smartlet?
    Datejust 36 (ref. 126200, 126234, 126233, 20mm) and Datejust 41 (ref. 126300, 126334, 126333, 21mm) are all compatible. Lady-Datejust uses smaller lug widths and is outside Smartlet's current range.
  • Is the Classic or Shadow finish better for the Datejust?
    The Smartlet Classic's hand-brushed SS316L is the most natural pairing with the Datejust's Rolesor or steel cases. The Shadow's PVD black coating offers a more contemporary contrast. Both are compatible and the choice is purely aesthetic.
  • 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.
