This is totally cool! IMHO!
Hamilton Aircraft Navigation clock. One of the more complicated ones. Only made 1944-1945 by Hamilton and Elgin.
It has 417 parts to it.
A date for the calendar which is the left small dial that is called the civil date. Top small dial is a minute time recorder which ends at 60 minutes, the far right is your small second hand which is always working, and the bottom small is your elapsed time in hours. Big and small hands are your normal hour/minute hands but in a 24 hour clock face. The large thin hand is your stop watch hand. Push the top right button and that starts your stop watch. Hit it again and it pauses. Hit it again and it resets the stop watch hand and will reset the minute counter dial small hand and hour hand.
It works and keeps pretty good time but the stop watch hand isn't functioning properly. It has to go in for service.
Also the face/dial will illuminate under UV lighting.
