Apple watch is an excellent add on to the iPhone. Its lovely and looking really great. I was totally amazed by this watch, what can be said about it! But its true that its not necessity its just luxary. I am an apple fan hence I got it, and I am totally satisfied! As it is water resistant, dont need to be worried about rain. And it has very good battery life also. Enjoying my time the watch is a great eye catcher. The watch can regulate and monitor the user activities such as heartbeat. So, allover I like that!
