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. 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.
