I have been wearing some version of this watch for 25 years now. The watches are great, the batteries last forever, the indiglo/light is super easy to read (along with the reflectiveness for low light. I don't even think about water, and have definitely worn this watch snorkeling, water doesn't touch it. This would be a 4.5 stars if allowed; the only thing keeping it from being a 5 star is the band gets loose, and breaks after a few years. usually the part that holds the "flap" first, then the part with the holes. You can buy replacement bands/ I usually just replace the watch because it's $20 difference and saves me the hassle. Also as another commenter said, the numbers and letters tend to wear off; which is okay, but the time they do you know what the buttons do. I would wholeheartedly recommend this watch to anyone without hesitation, despite the band thing.
