I am looking to get my first smartwatch. my basic usage will be for exercise (bike ride tracking, music navigation, basic stopwatch) and maybe to keep on during the day for calendar notifications. I will be wearing it on a rubber strap for the most part but it would be kind of nice to be able to put it on leather or steel on the rare occasion that I wear it in a less casual situation. Because this is limited use I am trying to stay in the lower end of the budget. $150 is my comfort number but the right one might take me up some. Of course saving money would always be great. Oh, and I am an android user and dont want to have to stick to a particular phone manufacturer. Any input from Sony or Asus owners? I am open to alternate suggestions as well. More waterproofing would be awesome.
