About the Octo Roma Naturalia family
Octo Roma Naturalia is a small group of Octo Roma tourbillons that use natural materials such as hard stones on the dial or case. The rose gold reference 103675, for example, uses the hand-wound BVL 206 caliber with a flying tourbillon, a skeletonised movement and a tiger's-eye plate behind it, in a 44 mm case. Other versions are in platinum or black-coated titanium, with materials such as malachite.
These are low-volume pieces, so each is judged on its exact reference, the condition of the stone elements and the complete set.
