It is a pendant created from an Ingersoll pocket watch internal brass plate. As always, I had to add a gear, this time a flywheel, and I used one of my miniature skeleton keys to add movement to the bottom edge. The upper left items are two clock/watch hands. What I like best about the piece is that the original engraving indicating the watch patent date spirals around the center.
Later, I changed the pendant, as seen here on the right.
This is still for sale in my shop on ArtFire.
