Actually the original Accutrons have passed their service life. I have a few and the only one that actually runs is an Omega F300. The battery the watches called for doesn't exist anymore and the closest replacement depending on the model may or may not work.

Parts are simply not available anymore.

The Westclock probably is not repairable. Those movmts were not designed to be repaired. If you have someone who specializes in vintage and antique watches you may be lucky.
