Female Round Dial Bracelet Watch Rhinestone Digital Quartz Wristwatch

The watch arrived non-working, the button does not press the hands, as the watch is glued in crookedly. They immediately gave me a full refund, thanks to the support service. I will give the watch to my little neighbor, she will get a beautiful bracelet for the New Year

Beautiful, but, how, do, they, open, to, change, batteries

The watch is not working, nothing moves, what should I do?
