To celebrate its 75th anniversary, Louis Erard is launching four new 1931 models, combining aesthetic creativity with technical excellence. The Moon Phase model, which is equipped with a complete calendar function, comes in a steel version as well as a limited, individually-numbered series of 75 in 18K pink gold, with highly original skeleton dials. The Regulator model is a blend of avant-garde and tradition in a novel shape with a “côtes de Genève” pattern.
