Wear a smartwatch with your A. Lange & Söhne

In short 387 A. Lange & Söhne references fit Smartlet One, led by Lange 1, Saxonia and 1815. Lug widths 18mm to 24mm. Installation uses the standard spring bars, with no modification to the watch, and is fully reversible.

Ferdinand Adolph Lange founded the manufacture in Glashütte in 1845, and it was refounded in 1990. Almost the whole catalogue keeps classic lugs with spring bars. 387 references are confirmed in our base, led by Lange 1, Saxonia and 1815. The Odysseus, with its integrated bracelet, is the exception.

Wear yours How it works
The problem
Choosing between health data and horological heritage every morning.
The solution
Smartlet One replaces your A. Lange & Söhne strap via the standard spring bars and positions your smartwatch on the same wrist, underneath. Both run simultaneously, with no modification to the watch.

Questions

Frequently asked questions

  • Does Smartlet work with A. Lange & Söhne watches?
    Yes for 387 references across the main A. Lange & Söhne lines in our base, including Lange 1, Saxonia, 1815 and Richard Lange, on 18mm to 24mm lugs with standard spring bars. The Odysseus is not compatible, because its bracelet is integrated. Check your exact reference in the table before you order.
  • Is Smartlet safe for a A. Lange & Söhne?
    Smartlet One replaces the strap only and never touches the case, the crystal or the movement. For a watch of this value, having the strap fitted by a watchmaker the first time is a sensible precaution. The setup is fully reversible.
  • Which smartwatch pairs best with a A. Lange & Söhne?
    For a slim dress watch, a screenless tracker such as Whoop or a slim Apple Watch keeps the stack discreet under the cuff. Your watch sits on top, the smartwatch underneath, on one strap.
  • 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.
