For anyone who already owns an Apple Watch, this is just a tech upgrade. Features are nice but worth spending over $600 for some upgraded features is worth thinking twice. If I didn’t need the upgrade for medical purposes...I wouldn’t have bought it. Also, some features do not work in Australia (e.g. EKG/ECG). Oh, and all bands for the 42mm fit perfectly on the 44mm. Anyone new to the Apple Watch world will love this Watch (as I imagine most owners do). I only bought the Nike version so I had another different band. The only differences between the NIke and Basic versions are; 1. Holes in the band with a tiny Nike tick on the inside 2. A tiny Nike tick on the back of the watch 3. Some exclusive watch face selections within the software. That’s it!
