Welcome and what you got there is a Longines Lindbergh Hour Angle watch. In the mid-1930s, the Longines-Wittnauer watch company marketed a line of watches designed in collaboration with Charles Lindbergh and P. V. H. Weems. The Hour Angle Watch sped computations for determining celestial lines of position. Its bezel and dial allowed navigators to read off the hour angle of a celestial object at Greenwich, eliminating a simple but troublesome calculation.

Oh, you just have to look a little harder, that's all. I googled LINDBERG WATCH BEZEL LOCK and came up with this

The markings on the bezel were for Lindberg's navigational computations. While he was doing this it was critical that the bezel not move by accident.
