Franz Hermle stops

Chain drive grandfather stops at around the hour, Sometimes 1 minute before but mostly 1or 2 after. To restart all is needed is to just barely faintly move the minute hand or very,very gently pull out om the main center shaft. It may run any time as long as 8 hours other times only a couple. Any Suggestions Will Be Greatly Appreciated.

Pongo, what shape is the movement in? Has it been serviced recently? May need oil and cleaning, or may need bushings. These movements will usually run until they are in terrible shape.

Harold is probably correct. My guess is a bushing is needed. The clock goes through a "warning" run at each quarter hour, but on the hour it also must power a warning for the chimes. The extra effort needed is probably stopping the clock due to power loss.
