Keep in mind you get what you pay for. That said, this is a very cute watch and my granddaughter loves it. It was a Christmas gift and when she first opened it and set it, it would not run. Later, when I was working on requesting an exchange, I noticed it was running. Hopefully it will continue to run and she will be happy with this watch. It's a unique style and perfect for a teenage girl.
