Okay, I am newbie just bought your ultra course worked on my first project. I have an issue, I’m working on a hermle 450 on the 1/4 hour the half hour and the 3/4 hour and the hour it chimes 5 minutes late how do i fix this
This is an easy fix. Hermle minute hands have a friction fit bearing. Take the minute hand off. With a pair of pliers holding firmly on the friction bearing and move hand backwards to where you think five minutes would be. Put in back on to check it. Adjust it until it lines up and you are set.
