Thanks for all the comments, looks like the only way is to get at the movement. As I am a complete novice in watchmaking, how could I best access the movement, and are there any special tools I need (can purchase)? I am quite willing to have a go at accessing the movement, but obviously do not want to do any damage...
Thanks again.

There are tools you can buy to help, but you may be able to open the case back with just your fingernails. If you look at the back you will see the silver metal ring with cutouts. Try putting the fingernail from each thumb into those cutouts and turning counter clockwise.
