Ebel

 By Bruce Shawkey

Found this ad in the March/April 1958 issue of Swiss Horological Journal for Ebel watches.

Here are some Ebel watches from the 1950s:

 Ebel was founded July 1911 by husband and wife Eugene Blum and Alice Levy (pictured below). They combined their initials to make EBEL, short for “Eugène Blum Et Lévy.” Unlike numerous other watch companies, whose origins were exclusively men; the EBEL Company has combined the values and qualities inherent in the male and female principles.
