As you can see from the photo, the battery leads have been cut off and most importantly the silver component (believed to be a timing crystal) is broken off the PCB and there's also two flying leads attached for an attempted repair. However, it was a working unit prior to the component coming off.
There is a link to instructions showing how to repair this component contained in another thread here:

This repair is a little beyond my somewhat basic soldering skills but if you think you're up to the challenge then it's yours, for free, including postage to UK only.
