Cute but very inexpensive
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.

Pretty but leather is mildewed.
I read the reviews but took a chance that the one I received would not smell mildewed. Oh my!! It stinks to high heaven!!! And it is too small for my wrist…another chance I took.
Instead of returning it, I’m going to try and replicate it using the watch and dangles with ribbon and cords.
It was wrapped very tightly in bubble wrap. Perhaps the leather would not have mildewed if it had been able to breathe. Boy! Does it stink!!!!!
