Louis Erard x atelier oï Le Régulateur Limited edition

Limited edition of 178 pieces, Le Régulateur Louis Erard x atelier oï – blends the art of fine watchmaking with modern architectural designs.

The dial was designed by atelier oï according to their artistic identity. A pure work of art, the slate grey, matt and polished dial eschews the hour markers and logo. It has three blued hands, respectively for indicating hour, minute and seconds. Originating from two off-entered locations, the rays form a minute-circle around the edge of the dial, with a line every five minutes and exactly sixty segments.

About atelier oï

Derived from the Russian word “troika”, a team of three, atelier oï was founded in 1991 in La Neuveville, Switzerland, by Aurel Aebi, Armand Louis and Patrick Reymond. With a team spirit and an intimate relationship with the material, atelier oï has been working for 30 years to dissolve barriers between genres and promote transdisciplinary creativity.

Born from an intuitive and emotional affinity between the three founders, atelier oï works in the fields of architecture, interior architecture, product design and scenography, with a collaboration between disciplines, creating holistic solutions from object to space. The co-founders have a strong interest in nature and natural materials, and their expertise in transforming these allows them to carry out both emotional and artisanal projects.

The three founders are architects, designers and boat builders, all members of the Federation of Swiss Architects FAS and headed the Swiss Design Awards as President of the Federal Design Commission between 2008 and 2016. Trained at the school of architecture funded by Alberto Sartoris in Switzerland, the founders also received honorary doctorates from this institution.

atelier oï encourages experimentation and cultural exchange, through their work with clients and their own initiatives, and as visiting professors in a number of leading institutions, including ETH Zurich, ECAL Renens, the Guangzhou Academy of Fine Arts and the Kuwasawa Design School in Tokyo.

The combination of local roots and international know-how has enabled atelier oï to design objects for a wide variety of national and international clients, including Artemide, B&B Italia, Bulgari, Foscarini, Louis Vuitton, Nespresso, Pringle of Scotland, Rimowa, USM and WonderGlass. atelier oï has also organised monographic exhibitions of its work in Zurich, São Paulo and Tokyo. atelier oï is also working on a humanitarian project for Smiling Gecko in Cambodia.

atelier oï’s projects have been recognised globally and have won some of the most prestigious awards including multiple IF Design Awards, Europan 3 Award, European Museum of the Year Award, Red Dot Award and the product of the year award from Architectural Record.
