Each of the eight one-of-a-kind watches in the 8 Marvels of the World series represents an exceptional architectural achievement. One of them is the Khazneh, part of the ancient city of Petra in Jordan. Three decorative techniques contributed to this recreation of the aesthetic force of the façade of the Khazneh, which is cut directly into the rock. They are bas-relief engraving, used to create volume and perspective; grisaille enamel, which uses light to dark shades of a single colour to suggest the predominantly red-brown sandstone, and fresco painting, in which the artist applies pigments to wet plaster. This technique requires the ability to work precisely but also quickly so that the pigments can penetrate the mass before the plaster dries. The result is an extraordinarily realistic depiction that continues on the engraved sides of the white gold case, the bezel and the lugs, giving life to this unique composition. The manual-winding tourbillon movement was awarded First Prize at the last International Chronometry Competition in Le Locle, Switzerland.
