Job Number 220071

Here we have a classic Hamilton railroad watch, 16 size, 21 jewels, 992b made about 1964.

Some Hamiltons have this little clip over the winding arbor, and some do not even though they have the cutouts. Many believe these parts were in all Hamiltons that called for them, and that they have been lost by watchmakers over the years. Maybe, but I have seen very close to mint movements that were missing this clip. At any rate, the part isn't essential as far as I can tell.
This 992b has an extra gear fixed to the main wheel that positions under the barrel plate. This gear engages the bevel pinion rather than the main wheel directly.

Also note the post that locks the main wheel. With this arrangement no main wheel washer and no left handed screw is needed.

This project is a grade 315, 12 size, 15 jewels, made about 1921.
There were no issues with the train, but it did have a broken balance staff and damaged balance jewels. It's not uncommon for an impact that breaks the staff to take a jewel or both with it.

Elgin staffs are riveted. The broken staff is cut off the balance wheel on the lathe. 
The remains of the cut hub are popped off in the stacking tool leaving a tiny washer. I always save these. You never know...
Riveting the new staff...
This tool can tighten a hairspring collet. It's one of those tools that is not often needed, but does the job perfectly when it is.

Here is a grade 313 Elgin movement, 16 size, 15 jewels, made about 1906. These 16 size Elgins aren't the flashiest of watches but they are real workhorses. Elgin sold a lot of them due to their high quality at a value price point.


An interesting case on this one... These are usually called "swing-out" cases and are not common on watches in this size range.
