I started running 4 years ago and got the Garmin 620. I figured I'd feel like an idiot if I bought an expensive watch, wore it a few times and then let it gather dust in a drawer. It worked. The watch barely lasts for my short runs so I'm in the market for a new watch.
Right before seeing your post I was looking at watches. I haven't researched Suunto yet but am considering the Garmin Forerunner 235, 735XT and 935 (the latter 2 related to the Fexnix 3/5. What led you to the Fenix ?
