With the challenges of producing dial in stone are well known to other manufacture, mostly these are produce in circular disk making the cutting action simpler and minimizing the risk of stress points from corners. F.P. Journe being F.P. Journe took a different approach. While ideally the stone dial would be cut from one piece, due to the configuration of apertures on the dial, it would not be possible due to the small amounts of material around the tourbillon and the offset dial, as well as the constant risk of fracture during cutting. The two crescent shaped pieces above and below are still very complex with numerous curves and differing radii, as well as the screw holes which have to be drilled, making for what one can imagine is a nerve wracking experience for the maker as well as numerous failed attempts along the way, before a perfect example is produced.
But all of the hard work pays off when one sees the illuminating effect created be the light passing through the ethereal green tone of the jade as well as the unique signature each dial has due to the veining within the stone. While it is impressive when viewed from afar, it takes on a whole new dimension when admired through a loupe. This particular example is further distinguished by the matching solid platinum bracelet which gives a watch known for its simplicity and compact nature, a suitably substantial feeling on the wrist making the owner abundantly aware of the importance of the work of art they are wearing
