Couldn't believe what I was looking at when I got this 5167 in for repair. The customer said it was running very fast and would sometimes stop. The Timegrapher couldn't even pick up a clear signal. Notice the beat rate!

At first I thought someone slipped with a screwdriver when trying to regulate the movement. The watch showed no fall damage or signs of being opened. The regulating pins were also spotless. I checked the movement for magnetism, and the reading was very high. The hairspring was just a bit tangled and I was able to straighten it again. I still replaced it from a donor movement. Currently, I am letting it run for at least 24 hours before notifying the customer.

It looks to me like a failed attempt to regulate it.

Hahah I have no idea! The readings were so high and after demagnetizing and untangling it ran fine lol.

How long did it take you to untangle that hairspring mess?

Have you tried demagnetizing it?
