Longines confirms production of this piece in 1942.

In the golden era of early aviation in the 1920s and 1930s, Longines was the watch most often worn by pilots and explorers. The main reason for this was the technical innovation of the firm, most notably the Hour Angle watch.

Considering the Earth will make one rotation of 360 degrees, a 12-hour dial is a useful tool for dividing up that distance over time. With the use of the inner rotating dial and the outer rotating bezel, an aviator could use the hands of the watch to effectively pinpoint his location on (or above) the globe.

The large size and features of this model speak to its history as a pilot's watch. Its big size made it easy to read in the cockpit and its large winding crown made it easy to wind and set even while wearing gloves. Of course, the technical and mathematical functions of it were incredibly important in this era as well.
