Hi Juli9870,

Try the steps and article below for unpairing and erasing the Apple Watch. After completing the steps it will allow the Apple Watch to disassociate with your Father's account. You will then be able to sign in with your Apple ID and password to link it to your account. You will need your Father's account information to complete the steps.

1. "Keep your Apple Watch and iPhone close together as you unpair them.
2. Open the Apple Watch app on your iPhone.
3. Go to the My Watch tab and tap All Watches.
4. Tap the info button next to the watch that you want to unpair.
5. Tap Unpair Apple Watch.
6. Tap Unpair [your Apple Watch name].
7. For GPS + Cellular models, choose whether to keep or remove your cellular plan.

If you want to pair your Apple Watch and iPhone again, keep your plan.

If you don't want to pair your Apple Watch and iPhone again, remove your plan. If you aren't going to pair with a different watch or iPhone, you might need to contact your carrier to cancel your cellular subscription.

8.Type your Apple ID password to disable Activation Lock, then tap Unpair".

To ensure that we're covering all of our bases, lets complete the following steps to verify your settings:

1. On your iPhone, open the Apple Watch app, then tap the My Watch tab. 
2. Tap General > Apple ID and verify that your Apple ID appears there.

If everything is accurate, we suggest that you reach out to Apple for further assistance. This is definitely unexpected behavior and they will be able to look further into this with you. You can follow this link to connect with them: Get Support

Hi Juli9870,

Thanks for posting in Apple Support Communities.

We understand that the wrong Apple ID is shown on your Apple Watch. Check on your Apple Watch and iPhone for your Apple ID.

On your iPhone, go to Settings > your name.

On Apple Watch, go to Settings > your name.

If your name doesn't show on either device, have you father sign out on the device or remove the device from Find My.

Remove a device from your Devices list

If you’re not planning on using a device, you can remove it from your Devices list. The device must be offline in order for you to remove it.

The device appears in your Devices list the next time it comes online if it still has Activation Lock turned on (for an iPhone, iPad, iPod touch, Mac, or Apple Watch), or is paired with your iOS or iPadOS device (for AirPods or Beats headphones).

1. Do one of the following:

* For an iPhone, iPad, iPod touch, Mac, or Apple Watch: Turn off the device.

* For AirPods: Put AirPods in their case and close the lid or turn the AirPods off.

* For Beats headphones: Turn off the headphones.

5. In Find My, tap Devices at the bottom of the screen, then tap the name of the offline device.

6. Tap Remove This Device, then tap Remove.
