Yes. Smartlet makes it possible to wear your Apple Watch and a mechanical watch simultaneously on the same wrist. Smartlet replaces your mechanical watch strap via the standard spring-bar system and holds your Apple Watch against the same wrist. Both watches run at the same time. All Apple Watch 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 Series 0 to Ultra 3 models are compatible with Smartlet. The Apple Watch uses a proprietary connector. A dedicated adapter, included in every Smartlet box, bridges it to the Smartlet module. 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 Apple Watch against your wrist with full skin contact maintained at all times. The following sensors continue to function normally: ECG, SpO2, crash detection, sleep tracking, skin temperature. There is no interference with the sensor array, and health data accuracy is unaffected.

いいえ。Smartletは、既存のスプリングバーシステムを利用して、通常の時計バンドと交換するものです。時計のケース、ラグ、文字盤に恒久的な変更を加えることはありません。取り付け・取り外しは数秒で完了し、完全に元に戻すことができます。機械式時計本体には影響がなく、元のバンドを取り付ければ、いつでもそのまま着用することができます。
