How do I change the Apple ID on my watch?

I tried what jechama8 had recommended above and it works (I think). I just downloaded an app from the watch app and it downloaded to my watch. For some reason, it still wants you to log into your iCloud account in the app, which you can do safely afterwards. I'm going to download some random apps to see if it works a couple more times. I'll keep you posted.

This kinda worked. I was already logged into my secondary ID in iMessage and FaceTime on my phone which is different than my iCloud account. I had to log out of iCloud on the phone, set up the watch then log back into iCloud on my phone. And it wasn't all that seamless. You should be able to easily select the ID you want to use and log in.

I have the same situation. On my iPhone, my "me.com" account is used for iCloud, and is also set as the "Apple ID" in iMessage. My true "Apple ID" is used for everything else.

When I paired my new Watch it only displayed my "me.com" account and would not let me change it to my Apple ID. I followed your instructions and changed my iMessage "Apple ID" to be my "Apple ID". After re-pairing the Watch it still showed my "me.com" account on the "Apple ID" screen. The next screen showed my Apple ID account as the iMessage account. So that's all it achieved. That shows that the Watch isn't using the iPhone iMessage account as the Apple ID on the Watch. I therefore set accounts on my iPhone back to the way they were at the start.

After completing Watch setup, I installed apps from my iPhone. They all work (but oh boy, some really are pretty lame on the Watch!). So yes, it simply doesn't seem to matter that the Apple ID on my Watch isn't my real Apple ID.

Perhaps Apple will make things clearer in a future Watch OS as we shouldn't have to go through this. It is their fault for telling "me.com" account holders that we should use our main contact email as our Apple ID.

Excellent it appears to have worked for me … many thanks! (same problem id1 for payment then mobileme came along ,…)
