A Seiko ship's chronometer
This is the old broken staff, and the new replacement I made,
for the flywheel in a Seiko QC-951. This is a very early and high quality
Quartz clock.

This clock experienced shock enough to break the pivot off this relatively heavy part. The gear and flywheel are friction fit on the staff shoulders, and the pivots run in jewel settings with cap jewels.
Here's what it looks like installed and ready to go back in the clock.
