Aero Watch
Aero Watch (often spelled Aéro) was a watch brand in Neuchâtel founded by Jean Grandy in 1937 and operated by Maxime Courvoisier from 1942 through 1973.
In December 1942, Crevoisier joined Aero Watch with founder Jean Grandy as the company was reorganized. He reorganized the company as a Société Anonyme on June 15, 1945 with 52,000 francs of capital. Both Courvoisier (president) and Grandy (secretary) remained with the company, and each took a substantial payment from the conversion. The firm was located at Rue Saint-Honoré 1 in Neuchãtel. The firm immediately established a workers fund and raised additional capital. Grandy left the company in November 1951, with Crevoisier solely in charge.
