Lancaster

The Lancaster watch company began operation in 1877. It was a smaller company that made watches at a lower than usual price point. It later became part of Keystone, and later still Hamilton.

This example is an 18 size, 15 jewel, lever-set movement.

This first image is a "before" shot. There's a layer of solidified grease on everything. 

On the dial side we can see the lever setting mechanism.

This watch has an old repair that is caused some problems.  The lever mechanism places some upward pressure from below the dial when the lever is extended, because the watch does not fit its case exactly. The dial can lift enough to touch the base of the seconds hand and stop the watch. Replaceing a dial foot made the dial more secure.

Later versions of this movement improved on the design so as to avoid this problem.

The Lancaster Watch Company only made about 200,000 movements between 1877 and 1882.
