This manual wind Autavia 741603 is extremely rare and was never featured in any of the original catalogues or sales material. The two distinguishing features are the dial with luminous Arabic numerals and the high beat Valjoux 7740 movement. It is interesting to note the bridge on all known examples is signed 7741 which is in fact the GMT variant of this movement. The majority of examples know are KAF (Kenya Air Force) military issue with engravings on the back case. This example is a rare non issue watch.
