Le Régulateur Louis Erard x Massena LAB Gold
This is not a watch, it is a meeting place between a contemporary watch and a 19th century marine chronometer with its own guiding principle. As William Massena explains: “A successful collaboration is one that makes sense. Louis Erard allowed me to mix codes, to cite the classicism of a master watchmaker like Antide Janvier, and to democratise a style that’s usually reserved for wealthy collectors”.

Exploring new possibilities
FROM THE SWISS JURA TO THE WORLD
Watchmaking is a passion that knows no borders. Undoubtedly inspired by the vast history and horological heritage of the Swiss Jura region, Louis Erard’s vision and reach are global – maybe even universal.
