I have a bichronous clock in for repair and I've never seen one before, therefore I have not promised I will repair it. Having looked at the threads concerning this movement I get the feeling that it is just a sychronous movement with a mechanical spring to keep it working after power is lost. Is this idea correct? I haven't been able to find any literature on the bichronous movement but Amazon has a book about the synchronous movement. So if there is just that additional spring I'll invest some money and educate myself. Thanks Sam

I have a couple of very old telephone clocks that have a small pendulum that operates the clock during a power failure.
