I learn to swim once a week. My clients are 2 and 3 years old so this is not deep sea diving. I understand hot water is not suitable for him and their pool is usually 76-78Β°. I had 2 lessons to do this week and the clock went completely off during my 2nd swimming lesson. My clock was 38 days. They broke 8 days after the return window! Unbelievable! I also got it in white and every time the watch was rubbed against a dark shirt it soaked up the color and wouldn't clean. All in all, the watch was a bad buy. Much luck!
