The outer ability to move for a countdown is literally amazing and very useful for counting breaths or drops per minute when multitasking. The white on the outside goes great with any color, and I love that the teal on the inside is an eye-catcher. I had an expensive watch with gems that I had to return as gems carry germs :( I was really sad about that but to be honest...this watch cost more and was useful. Lets be honest nursing school is expensive and I needed all the help I could get.I'm sure I'll be ordering more soon.It's only been 1 semester since there's only splashing when washing hands but so far no problems with water contact.
