I purchased a new replacement Hermle 261-080A mechanism to replace the original unit in our 1983 Zaandam Dutch Clock. Before I installed the new unit, I had to swap two parts from the original mechanism over to the new mechanism, those parts being the 6 cm suspension post and the anchor/ crutch assembly. The two new parts were much shorter than the original. After reinstalling the new components, I could not get the clock to run for more than 30 seconds, regardless of how much I move the clock assembly to find the right beat sound. I removed and bench mounted the new assembly out of the clock, leveled and plumbed it and still couldn't get it to work. I then reinstalled the new suspension post and anchor/crutch assembly, used the new leader with the original pendulum and weights, but still could not get this to run. My wife and I purchased this clock in February and it worked fine for approximately 3 months and then we started noticing that every time we wound it, it progressively became harder to get it started again so I ordered a replacement mechanism for it based upon the information on the back plate of the original. Is it possible that the original mechanism is a 23 cm mechanism with a 31 cm stamp, based upon the length assembly depicted in my photos, if that makes sense? Would the gearing be different between a 23cm and a 31cm mechanism? and would it be enough to keep the clock from running? Please any feedback would be much appreciated.
