Revised 8/1
I still love the watch but I'm horrified at the price this vendor is charging. I bought this watch in 2013 for $30!!!

The watch is beautiful and my boyfriend loves it. That being said, my boyfriend could sleep thru an earthquake so my hopes were dashed when the vibration didn't awaken him. The vibration alarm only lasts 10 seconds but you can set up to 5 consecutive alarms if you want. For now I have to deal with the crazy loud alarm he needs to wake up though I am considering putting the dog's shock collar around his ankle...
