Job Number 170006

This watch is Elgin's grade 472, 16 size, 21 jewels, made about 1927.

Here is a problem with the center wheel jewel. The broken one is in the foreground and the other is the replacement.

Well replacing the balance staff was easy. I chucked the balance in the lathe and started to cut off the back hub when I noticed the balance wheel was wobbling an awful lot. I took it out and the old staff fell right out and onto the floor. Apparently it was not properly riveted to the balance wheel the last time someone did this repair. Well then, saves me some time...
The truing calipers are used to make sure the balance is flat and round.

The roller jewel turned out to be loose too. I re-seated it.
