So in terms of rarity, this is certainly one of the oddest watches Longines made for presumably the WW2 Italian Regina Aeronautica.
If you are unfamiliar with the Longines big pilots, these 47mm Longines are almost always made of silver or steel. The two rarest metals are solid gold and until recently known; Chrome over Silver. John Goldberger researched this watch with Jennifer Bochud - Longines Heritage Museum. This was chromed by Longines Factory at St. Imier. This was done while the watch was being built by the factory according to Longines records.
I don't know much about the history of this watch. We found the name of one of the two other existing watches but so far the information we have about the personal history of the person doesn't seem to match what we would expect for an owner of such a technical professional watch. We likely have the wrong person with the same exact name.
This watch appears in John Goldbergher's reference books on Longines watches. In fact, I like to think he chose it for the cover of his book. He used the design of course of a typical Longines Hour Angle (Lindbergh) watch. Longines records seems to indicate 10 of these watches were made. Only three exist today. This is presumed 7 of 10.
