Repair Summary

Not worth repair.

At full-throw of the pallet fork, the pallet stone does not clear the ratchet wheel tooth:

After mainspring replacement, the watch ticked through two or three teeth of the ratchet wheel, then get stuck. Normally, I would look into adjusting the ratchet wheel or pallet fork, but since the case was bent and the crystal shattered, I believe the entire movement was slightly warped throughout. When resassembling, the bridge holes didn’t quite line up, further indicating the whole movement is bent.
