Louis Erard invited atelier oï to look into the question and the answer is a new original dial, the third part of the series of collaborations already co-signed by Alain Silberstein and Vianney Halter. Breaking new ground, the collaboration leaves the strict field of watchmaking, since atelier oï works in the fields of architecture and design. Le Régulateur has naturally imposed its own rhythm: the hands (hour, minute, second) become centres from which rays emerge, generating visual kinetics that each movement of the wrist animates, giving the two-dimensional dial the depth of a radiant architecture. A pure work of art, which nothing can break, not even the Louis Erard logo. Reading the time comes out somewhat dematerialised - you have to mentally reconstruct the puzzle of hour angles - but all the links are not broken: the minute-circle still appears around the edge of the dial, with a more pronounced line every five minutes and exactly sixty segments. The timepiece is limited edition of 178 pieces.
