I have a wall clock with a Hermle movement that is in rough shape, dirty, gummed up, etc. Will take some work to restore which is above my level of expertise at this time. I have found another movement that is new, never used but a few years old. They are the same part number 341-020 but they have different pendulum lengths something like 11cm vs 35cm (don't have them in front of me so I could be in error on those two numbers). Is the only difference between these the shape of the pallet over the escapement, that is the only thing that looks different. Could I swap these and re beat the clock or is there other gearing that is different.
