Apple watch is a stylish looking smartwatch launched by apple named as I Watch. My brother owns an iWatch and I have also used it and here is my personal experience: -
1.Watch build quality is good, touch response is good but icons are very small so ui needs perfection.
Also honestly smartwatches are made for style statement cause the current state of smartwatches will allow you do to only few functions.
Notifications are greatly displayed but iWatch is way costly so only if you deperately need it then only buy.
I rate it 3/5
