If your Apple Watch won’t pair with your new iPhone 18 Pro, try these steps before erasing the watch.
- Update your iPhone: Go to Settings -> General -> Software Update and install any available update.
- Restart both devices and make sure Bluetooth and Wi-Fi are enabled on your iPhone.
- Open the Watch app on your new iPhone, tap All Watches -> Add Watch, and follow the onscreen instructions.
- If you still have your old iPhone, keep it nearby and check whether the watch is still paired to it. Transferring from the old phone may be necessary.
- If your new iPhone says Start Pairing but the watch is still paired to the old phone, unpair it using the Watch app on the old phone first. This creates a fresh watch backup.
Important: Don’t erase your Apple Watch until you’ve checked whether you can transfer it from your old iPhone.

What happens when you try to pair it? Does your iPhone fail to detect the watch, show a pairing error, or ask you to update the watchOS version?
