PMed you my number. It's an easy fix.
The tic toc clock is run by a small spring. The clock rewinds the spring by a small short in the contact area. It's kinda of funny how simple the clock is. The two contact areas slowly get closer to each other as the clock spins until they get close enough to short out and the tiny little short (you'll see the spark) fires and rewinds the spring. I'll bet you the contact area on the two contacts are corroded and that's why it works for a minute or two but does not keep going.
