This is a cool watch. Two thing one needs to know about this product: you have the option to leave the lights on or off. Leave it on saves power. So it's your choice. Second, as described, the watch isn't water resistant. Since I don't plan to immerse it in water, shower with it or go into the swimming pool with it, that doesn't bother me. Not water resistant doesn't mean you have to take the watch off when walking in the rain. The watch comes with instructions. Make sure you read them and you won't be disappointed. Anyway, to speak for myself, I'm 100% satisfied. I have many watches and I will be using this one as a dress watch. It's impressive.
