Yes. Smartlet makes it possible to wear your Huawei Watch GT and a mechanical watch simultaneously on the same wrist. Smartlet replaces your mechanical watch strap via the standard spring-bar system and holds your Huawei Watch GT against the same wrist. Both watches run at the same time. All Huawei Watch GT health sensors maintain full skin contact and operate normally. You no longer have to choose between your health data and your mechanical watch every morning.

All Watch GT 3, GT 4, GT 5 models are compatible with Smartlet. The Huawei Watch GT uses a standard lug and attaches directly to Smartlet with no additional accessory. The setup takes under two minutes and requires no tools. Smartlet is compatible with any mechanical watch between 18mm and 24mm lug width, covering the vast majority of the market including Rolex, Omega, Tudor, TAG Heuer, Seiko, Breitling, and IWC.

Yes, all sensors remain fully operational. Smartlet positions the Huawei Watch GT against your wrist with full skin contact maintained at all times. The following sensors continue to function normally: ECG, SpO2, skin temperature, stress tracking, TruSeen heart rate. There is no interference with the sensor array, and health data accuracy is unaffected.

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.
