This is a non-working pocket watch case. It wasn't used directly by the cast but was used as a set prop. Im not really sure as to which scene it is in but it was sold via auction from Premiere Props. 

I have had this for a couple of years now and don't really know much about it due to being given it by a friend.

If you have any questions please don't hesitate to let me know! Comes with original flyer for the auction too.
