Longines Weems Military Crown Locking Bezel SOLD

An excellent example of the famous Longines Weems military watch with double crown bezel locking system used by pilots to keep track of flying time.  The Weems navigation system, developed by Captain Phillip Van Horn Weems in the 1920's, gave birth to this watch design eventually patented in 1929.  It was eventually mass produced to be sold to the general public to satisfy the aviation enthusiast frenzy of the 1930's and 40's.  This particular example is in excellent condition in a desirable steel case with two original crowns, signed on the dial with the US patent number 2008734.  A must for any aviators watch collection.
