Compare the Apple Watch Ultra 3 vs. the Ultra 2, and you will see that the new model looks quite similar to its predecessor. You’ll need to squint to notice the Ultra 3’s slightly larger display. And most other changes are internal, like faster charging, longer battery life and satellite connectivity.
Otherwise, this is basically the same rugged smartwatch that Apple launched two years ago. So, if you already own an Apple Watch Ultra 2, should you consider upgrading to the Ultra 3? Or should you save your money instead?
