OBSERVATIONS:

Extremely rare Eberhard & Co. three-register one-button chronograph (pre Extra Fort). This watch was the world's first 3 register chronograph with hour counter. Watch highly desired by collectors due to the few units manufactured.

The top pusher controls all the chronograph functions: start, stop and reset.

The bottom pusher is not actually a pusher. It is a sliding button that locks the upper push button. When the lower button slides up, the upper button is locked and does not work. When the bottom button slides down the top pusher will be fully functional.
