I bought a Timex Ironman 50 lap watch at Target that was supposed to be water resisitant to 100 meters. It lasted about 90 seconds in the pool before water got inside it and the face went blank. Was this just a bad one and I should try another one? Or do I try to find a waterproof watch? Is there such a thing?
