The Millenary Onyx Tourbillon overturns existing ideas, and in particular that which holds that the design involves the exterior of the watch and thus its outer garment, while the inside is essentially functional. Things are very different on this model, in which the inside and outside form a seamless whole merging functionality and design.
Inspired by The Millenary Chalcedony Tourbillon, this version is equipped with an openworked onyx mainplate. This magnificent realisation is a perfect demonstration of Audemars Piguet's unique know-how in machining natural stones like Onyx.
