Hi there! I understand your iTouch Air 4 watch keeps restarting on its own, and I’m here to help you get this sorted out. To begin with, could you tell me if this restarting happens randomly throughout the day, or does it occur during specific actions like syncing, charging, or using certain apps? Also, have you noticed if your watch’s battery level might be low when this happens?

While you check on that, here’s a step-by-step approach we can try to fix this:

1. Soft Reset the Watch: Press and hold the power button on your iTouch Air 4 watch for about 5 seconds until it restarts or the logo appears. This can clear temporary glitches.

2. Check Battery and Charging: Confirm your watch battery is charged. Sometimes, a faulty charger or low battery can cause restarts. Try using the original charger and charge the watch fully.

3. Update the iTouch Wearables App: On your Windows device, if you are using the app with an emulator or companion software, ensure it is updated to the latest version, as app or firmware incompatibilities can cause reboot loops.

4. Unpair and Repair: Unpair your watch from Bluetooth on your device, then reset the watch (soft reset or via settings if possible) and pair it again. This can refresh the connection and resolve software conflicts.

5. Check for Firmware Updates: Sometimes the watch’s software needs an update to fix bugs causing restarts. If you can access the watch settings or the iTouch Wearables app, check for firmware updates.

6. Factory Reset (if available): If the problem persists, consider doing a factory reset on the watch to restore it to default settings. This should be done only after backing up any important data.

If you’ve already done some of these steps, please let me know so I can guide you further with advanced troubleshooting! Also, does the restarting happen while it’s connected to your device or even when it’s not connected?

Looking forward to your reply so we can get this resolved for you.
