I wanted a watch for swimming, hot tub, steam sauna and the shower. Unfortunately, I found out later that the watch should not be exposed to warm/ hot water, so much for the hot tub and sauna. The rubber seals are not made for warm/hot water. It was suggested to me however, that the watch really wasn't that expensive and I should just use it as I like. I must admit I am tempted but I still take it off when I am in the hot tub and sauna. One should also note that the watch is not easy to read in the dark. I cannot imagine using this in deep, dark water, the numbers do not glow.
