Elgin Grade 70, Animated

The grade 70 is an early 18 size Elgin design.  This 15 jewel example was made about 1881.  There are 17 jewel variations as well.

This image shows the details of the lever-set mechanism.  It's a little different in its use of a wheel with teeth on the inside to engage the cannon pinion when setting.

The cannon pinion is not installed on the center staff in this picture.
