Wear a smartwatch
with your Timex

Smartlet One is compatible with all Timex Expedition, Waterbury, and Q Timex references using 18mm to 22mm lug widths, natively supported with no adapter. Installation uses the standard spring-bar system - no modification to the watch, fully reversible in seconds.

Timex made the Indiglo backlight the universal standard for reading a watch in the dark. The Weekender was the default field watch for a generation. The Q Timex revival brought back the 1979 reference at a price that made vintage design accessible. Timex proves that watchmaking quality and everyday use are not in conflict. Smartlet One fits Timex references without adapters - the spring-bar system is the same whether the case costs 50 or 5,000 euros.

How it works

Three steps to both watches on one wrist

01
Choose your strap
Smartlet One is your new strap. It replaces the original bracelet or strap on your Rolex using the same spring-bar system. Lug widths 20mm / 21mm are all natively supported.
02
Clip in your watch
Attach the Smartlet strap to your Rolex by fitting the spring bars into the lugs, exactly as with any standard strap change. No tools required. Fully reversible in seconds.
03
Clip in your smartwatch
Slide your smartwatch into the Smartlet module. It locks onto the strap module on the wrist side of your wrist. All sensors remain fully operational. Both watches run simultaneously.
