Elgin Grade 540

This watch is another very good Elgin model. It also has a motor barrel, but with a slightly different arrangement. There is a snap on cap on this type, although the arbor is fixed to the ratchet wheel.
The movement is a grade 540, 16 size, 23 jewels, made about 1938. It is a B.W. Raymond model.
This is a setting cam. It has a post that extends through the plate where a spring pushes it. This one is broken. A replacement is on the right.
The screw bound the setting cam. There is a slight variation in the replacement part. A little washer will correct the issue.

This washer is a remainder from replacing a riveted balance staff.
 This is the new setting cam in place.
This watch has a two piece double roller. These take more care to deal with.
Also, here is a photo showing the broken lower pivot on the balance, having the roller and hairspring already removed.
A replacement staff needs to have the right pivot size. It should fit in the balance jewel such that it stands at an angle. This looks about right for proper side-shake
