Looking for a smartwatch to track my activity. Not too bothered about other features but want the full range of activity monitoring, waterproof and decent battery life. Never had one before and really struggling to know what to get. Fitbit is putting me off because of its subscription for the premium features. I like the look of Samsung ones as my phone is Samsung but even with them there are too many to choose from and I can't make sense of it. So, what watch do you have and what do you recommend?
