Can someone help me identify this unusual watch I purchased at a garage sale in Michigan in the 90's? It has no hands, but instead has 3 windows with dials that turn behind the windows. Watch is powered by a winding mechanical movement. It actually ran for a couple hours today, but it's finicky to keep running.
