Just managed to trade my Tutima Mil chrono from the late 80s for this rarish SINN cockpit clock from a German airforce military aircraft. From my googling, this model was issued to all German airforce planes from the the 80s to 90s when the Tornado jet fighter was active in the RAF, Luftwaffe, and Italian airforce.
My friend G. in Athens, Greece got possession of the clock and made his own desktop holder for this amazing chronograph!
