The Swiss architect Pierre Studer has designed three luxury VIP rooms for Piaget. Located in the Plan-les-Ouates manufacture in Geneva, the rooms are light and subtly decorated, creating an exclusive and refined ambience. They have been conceived in the form of a watch movement, and feature the three circles designed by Vitrocsa. These three overlapping circles can be used either to create three distinct VIP spaces, or a single large space. The centre circle has a radius of 3800 mm and is made up of eight sliding leaves, while the other two circles each have three sliding leaves and a radius of 2700 mm. The height of these assemblies is 3200 mm. The main challenge was meeting the customer's acoustic insulation requirements.
