There is a site you can look up smart watches, add them to be compaired and then get a great side-by-side view. specout.com.
One of the biggest issues with all smart watches is looks. Yes, in the battle of the wearables this matters a lot! Ladies? Would you wear a big plastic clunky watch out on a first date (or almost anywhere?). Watches that do not have an option for a femanine look will chop their target market by 50%. Food for thought. (Men if you buy your lady a big plastic watch don’t be upset if that $100 + item is worn only to make you happy and never when you aren’t around.)
My last note is functionality, if your watch doesn’t do much you will most likely not remain interested long. A watch that you can add and remove and have a choice on functionality so that you can customize your smart watch to meet your personal needs will do best. So before you buy I advise that you make sure that you are getting a watch that will be able to match your personal needs in functionality.
