Please don't anyone mock me for asking this question, as it is a serious one. I'm entering my first contest and my friend told me I should wear a watch with a timer on it so I could time the heat which is 15 minutes. So I went out and bought this expensive surf watch and used it today for the first time and I find that as I am taking those last few paddles to stand up, the watch is deflecting water and messing up the stroke. Is this my imagination or is this really happening? If any of you have been in a contest, do you wear a watch? What do you think?
