This beautiful Millenary Onyx Tourbillon watch seems to have the dial floating to show off the wonderful Onyx movement & Tourbillon.
The pink gold case is set with diamonds and so continues the theme of the movement.
Inspired by The Millenary Chalcedony Tourbillon, this version is equipped with an openworked onyx mainplate.
This magnificent realization is a perfect demonstration of Audemars Piguet’s unique know-how in machining natural stones like Onyx.
