Reading Time: 5 minutes

Louis Erard marks a new stage in the accessible creation watch, with a fresh look at all the crafts that make up watchmaking. For this new collaboration, Louis Erard turns to architecture and design with atelier oï, a regional company that has been shining internationally for 30 years, and a radiant watch, too: Le Régulateur Louis Erard x atelier oï.

How to materialise space and time? How to materialise the contemporary spirit of the watch when connected technology has disconnected watchmaking from its primary necessity: telling the time?

Le Régulateur Louis Erard x atelier oï

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. Once more based on the emblematic model of the Maison: the regulator. Once again with the desire to bring together key players in traditional watchmaking culture. And again with the desire to bring together key players in Swiss know-how: atelier oï and Louis Erard are both regional companies of international stature.

Breaking new ground, the collaboration leaves the strict field of watchmaking, since atelier oï works in the fields of architecture and design. The invitation did not come about by accident, however. The workshop, based in La Neuveville, a satellite town of Neuchâtel, has been close to the watchmaking industry since its creation precisely thirty years ago and the watchmaking world has played a major part in the development of the company. Going back as far as the 1990s, there has also been a warm relationship between atelier oï and Louis Erard, as illustrated by the current manager Manuel Emch, who began his career with an internship at atelier oï and who has collaborated with it ever since.

In three decades, atelier oï has become a brand in itself, reputed around the world, rewarded with more than thirty distinctions that illustrate its uniqueness. Moreover, the name, oï, is borrowed from the Russian Troika, a word that symbolises the energy generated by a trio, in this case, Aurel Aebi, Armand Louis and Patrick Reymond, the three co-founders.

Talents, an anniversary, connections, Le Régulateur Louis Erard, the planets were therefore aligned for this collaboration to emerge.

The objective, for Louis Erard, is once again to break down barriers in the world and make accessible what is often reserved for specialist clientele. With this added challenge of plunging without a net into contemporary creation, with all that entails of references, reflections, diversions and shocks.

atelier oï proceeded in a basic way: “To radiate from the centre outwards.” Taking care to reduce the technical vocabulary as much as possible, reminiscent of the shape of a sundial. The result is a surface engraved with asymmetrical rays, the light of which reveals reflections and contrasts – echoing the passion of the members of atelier oï for the material and the play of light. The art of engraving being expressed here in its essence: drawn lines. These lines create a space, to which the hands add the dimension of time.

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. A nod from atelier oï to the smartphone generation: “Today, the object watch has another meaning.”
