Automatic Fortis Flieger Military/Aviator chronograph with case back ref 597.10.141.1, with its inner and outer boxes. This one is a first generation model (from the period of 1987-1997.) Physically, the watch case, back, bracelet, flat sapphire crystal and dial and hands are all in very good to excellent condition; it looks like it has been stored away most of the time.
The watch keeps precise time; the chronograph starts, stops and resets as it should. The lume on the dial and particularly the hands still illuminate. The watch comes on its original signed link bracelet and with its inner and outer boxes. It measures 40mm wide excluding the crown.
