I hope you can help me, about the precise dates of watch.
Watch is Aero Watch Neuchatel powered by mechanism Landeron 48.
Watch the unusual design casing, gold plated and below gold plating the alloy is not iron neither brass (white metal, but does not act magnet, I am a little confused).
Dimensions are 37 mm without crown.
Watch is made between the late thirties and early fifties of the twentieth century - probably between 1940-1945, so I guess - So my little knowledge can determine the time of production.
I hope that more experienced colleagues on this forum, can precisely determine time of production of this watch, and eventually the material which is made casing (because if I polished casing that can not be damaged, and one foot is a little distort, but I'm afraid rectify, that would not be broken, because I do not know the origin of the alloy.).
