Removed my hermle 1050 020 with floating balance, tripple chime to oil pivots... after reinstalling into case the clock is running about an hour fast per day and has no more range to reduce the speed any further. Was running fine before taking it out of case. I dont believe i touched anything that would have caused this. Ive read the drive train might be losing power and this can happen? Deteriorating main spring maybe? Also, the chime sequences are messed up now and the 3 chime selector is giving me issues, as well as the chime hanging up badly through its chime cycles.
The movement is dated 81' and im sure it hasnt been broken down for a proper cleaning and oiling. All pivots are within reason as far as wear... no obvious need of bushings.
I am willing to break it all down and give it a run on cleaning. I hear these are finicky though and likely better to be replaced. I dont really want to replace it though... any suggestions as to what to look for? I found the hermle service manual. Considering reworking the unit. Can anybody help?
Can provide pictures or videos if needed upon request.
Thanks!
