One such example is this 38-mm Calatrava, a limited edition of six watches in rose gold. The dial depicts “the arrival of the car that symbolizes the dolce vita in the enchanted setting of Lake Como, bordered with brightly colored houses.” To trace all the contours of the houses’ windows and the Cinquecento’s bodywork in Grand Feu cloisonné enamel the enameller laid down about 60 cm of gold wire (~0.39 g). Patek Philippe: “He then brought his picture to life with a palette of transparent, opaque and opalescent enamels in an opulent 40 colors. A further 17 colors of miniature painting on enamel brought out the ripples on the lake’s surface and the slight haze in the sky above the green hills, lending the scene a sense of depth. Each enameled plate called for about 12 firings at a temperature of 830°C.” This watch is powered by the caliber 240 ultra-thin self-winding movement, visible through a sapphire crystal case back. Retail is CHF 115,000.
