At the confluence of Haute Horlogerie and decorative art, Audemars Piguet has created a small marvel of equilibrium and refinement: the Edward Piguet Moss Agate Tourbillon.
Moss agate is a semi-transparent natural stone belonging to the chalcedony family. Its name is derived from the small plant-like mineral inclusions in the stone, making each piece quite unique. However, the irregular structure of moss agate makes it a difficult stone to work with, and it is impossible, for example, to use the classical methods such as diamond-bit shaping. In order to cut the moss agate plate that serves as the base of the movement, Audemars Piguet had to develop an ultrasound technique using a liquid-based abrasive – a world’s first in watchmaking.
