Job Number 180028

This is an Elgin grade 316, 18 size, 15 jewels, made about 1909.

See the album for this project here.

This movement needs a new balance staff. The old one, with a broken pivot, is cut off in the lathe.

When the hub of the old staff is all but gone, the staking set is used to break it away. This leaves behind a little washer that is all that's left of the hub.

The balance wheel is riveted onto the new staff.

I find the hairspring collet needs to be tightened. It's way too loose on the new staff. This isn't unusual. Things don't just fit.

Ticking...
