To me there are two things I particularly like about the "fancy" watch (which for me is the Garmin with the Referee Watch app). First, the vibrate feature. It means I know when the watch says time is up, but it isn't beeping so that players hear it. Second, I like that I can have all the times--halves, half time, extra time, all set up so I don't have to do anything during the game. For me, everything after that is a bit of gravy and mildly useful. Kinda nice from curiosity to know how much I ran, and the stoppage time feature (which I typically only use when there is an injury with the coach coming on) is kinda nice, though I mostly keep a running tally of any time I'm going to add in my head anyway.
