I almost did run into a lampost as well! Not because I was looking at my watch but because I was running past a primary school looking at the kids playing and thinking how great it was to see so many little girls running around playing football (soccer), just looked ahead in time to take evasive action. It would have really hurt and been really embarassing as I was approaching a crossing and there was a big queue of cars!
I have almost done that myself, from not looking where I was going!
