Do I have to upgrade my Apple watch series 2 to be compatible with my new Iphone 14?

It looks like you'd need to update your watch.

My statement is based on this:

- watchOS 9 requires iPhone 8 or later with iOS 16 or later and one of the following Apple Watch models:

• Apple Watch Series 4
• Apple Watch Series 5
• Apple Watch SE
• Apple Watch Series 6
• Apple Watch Series 7
• Apple Watch Series 8
• Apple Watch Ultra

Not all features are available on all devices or in all regions or languages.

Which I got from here:

watchOS 9 - Apple

But... I'm not sure how recent of a watchOS update a Series 2 is capable of. Maybe a Series 2 can't be updated to wOS 9. If that's true, then there might still be a chance!

Theoretically fully updated series 2 (OS 6.3) will pair with any iphone. Ensure the iphone 14 is on iOS 16.2

However pairing series 3 is 50:50 chance with a following wind, series 2 is even more difficult, simply down to the low RAM that these 6 year old designs have.

Good luck, you'll need it.

Or get a new watch - even an SE2022 is a quantum leap over the series 2

Nice to see you back fieryjack! You had us worried.
