As a hopefully budding triathlete, I'm finding I need a way to keep track of time. I don't want to purchase a Garmin type device or a heart rate monitor at this point, just a basic way to keep track of my times. I know it needs to count up, digitial is probabley better, water proof is a must for swimming.
I know this sounds kind of silly, but what exactly do I need it to do? I've looked at some with all sorts of features but I don't know which ones I really need and which I really don't need. Can someone help me out?
