Harry Potter Hogwarts Watch Wrist Strap Used

This is a very used Harry Potter Hogwarts Watch. The watch band fits with in a arm band and the Hogwarts crest moves to the side to reveal the face of the watch. This has been used alot when I first got it, however in the past 10 years it has been in storage. I replaced the batteries before I put it in storage but it looks like it may need its batteries replaced again. I'm not sure. Please look at all the picks to show the wear and tear. Overall this is a beautiful piece just needs some TLC to revive it again.
