Job Number 160215, Waltham 1894 Model, Grade 220

The first challenge with this next Waltham is another case screw with the head broken off. Fortunately it wasn't too much trouble to get it out.

 The mainspring looks fine...

This is the "shipper" mechanism for winding/setting. It's found on many old Walthams and is a little different. It has more parts and and is a little harder to assemble than the design used on other common American watches, but it does work a little better too.

These parts are all related to winding. What part goes along with these but isn't shown?

The answer is posted here.

This is a 12 size movement, 15 jewels.

This one has an unusual swing-case. Swing-cases are more commonly found for larger watches.
