setting for beat error for cylinder escapement
canthus posted a topic in Watch Repairs Help & Advice
I am currently working on an old small pocket watch which has a cylinder escapement. The hairspring on the balance is a little out of shape towards the regulator end. If I have to remove the hairspring from the balance staff to resolve shape then how do I reset it back on the balance staff so that it will be in beat, or near enough as a starting point before adjustment of the hairspring collet position on the balance staff. I know with a swiss-lever that the table jewel can be visually be aligned with the pins and the lever pivot and escape wheel pivots, so is there a similar method for a cylinder escapement bearing in mind there is no lever. Any advice much appreciated.
