Hi, Pictured are my two Longines aviator watches. 1) 1947 single button fly back chronograph. Steel 47 mm case with back stamped NAV. 109. Original delivered to the Netherlands. 2) 1947 Lindbergh Hour Angle. Steel 47 mm case with sterling silver bezel. Originally delivered to Argentina, and was originally owned by an officer in the Argentine Air Force.
Ugh. Nice. Very nice. Have been on the hunt for the large stop second. Do let me know if you are evr foolish enough to let it go.
I've followed their ascent as well over the past decade. And I have also seen Phillips auction of rare hour angles with interesting provenance for 140. I still think reasonable examples of the Second Setting can be found for <25k and my point was simply their prices vis-a-vis 13zns.
