Notes

The Aéro-Compax was patented on November 6, 1940. It was specially designed for ailrline pilots, with an extra dial for storing times. The hands in the extra dial are totally independent of the central ones, and can be adjusted without causing any interference to them, thanks to an additional crown on the 9.
