I'm currently in iraq and when I had read that this watch vibrates it was perfect. The other great thing about this watch is the fact it has 2 times on it so now I can track the time back in the States. I like the 2 alarm settings as well and the vibrating feater is perfect for when Im on a convoy and it i know when the hour has changed because it vibrates. Other reviews said they had prob;ems with the water getting in it I haven't had that issue since I wear it in the shower. The watch face is big and so are the nmbers so there is no question on what time it is. Buy this watch its worth the money.
