Hi all hope everyone staying safe
I am hoping someone can help me as I have a 30 torsion clock ( I know it’s not a anniversary clock) but it’s same principle hence in this forum.
Anyway I have stripped and cleaned it and I runs fine, but when it is fully wound it gains 30 minutes a day but when it gets to about 2 1/2 to 3 weeks it looses 15 to 20 minutes a day .
Anyone have any suggestions?
