The “Ermeto” design was created by Georges Huguenin, Paul Huguenin-Davoine and Alfred Dubois, of Huguenin Frères et Cie, Fabrique Niel, Le Locle, who in 1926 patented an idea of an ordinary rectangular watch case protected by “an outer ornamental casing, the two halves of which are adapted to slide apart to expose the dial”. The idea was patented in a number of countries, starting with England on October 11, 1926 (English patent No. 278 669), and the next day in Germany (German patent No. 443 555).

Movado Factories bought the patent rights and a year later patented the winding system by sliding the case open and closed (English patent No. 296 721 of September 6, 1927). The design became very successful and Movado manufactured it constantly for the next half-century.
