Universal Genève A. Cairelli Regia Aeronautica

Hello, I would like more information about this airplane chronograph. I only know that it was mounted on Italian aircraft during the Second World War, any additional information would be of great help. I found this item in a flea market and would like to know how much it could be worth. Thank you all

It’s worth about $100. PM me if you want me to take it off your hands.
