That's very kind of you! I will keep this option in mind (34.60mm length - hopefully same as your spares), but hope to fix this issue by myself. I did replace several Balance Staffs on 8.5-13''' wrist & pocket watches in the past. Thank you!Yes, I checked and it's ten. I have a couple extra's lying around for parts, so if your repair doesn't work out maybe I have one that is the same length and same number of leaves on the gear.
