Dome table clock in Longwy enamel on faience.
The first dome table clock enameled on faience, this unique piece is adorned with a swallow, harbinger of spring, in a decor of flowers on a turquoise-blue ground. To create this refined decoration, Patek Philippe turned to the exclusive technique of Longwy enamel, named for the town in northeastern France famous for this type of production.
The artist laid out the design on the different bisque elements, drawing the black outline or cerne characteristic of this technique. He filled the motifs with a palette of 12 opaque enamel colors, creating a slight relief. Then he refined the details, using a brush and 9 pigment shades to bring out volumes, shadows and light. Each enameled plate required 5 firings at temperatures ranging from 745°C to 1020°C. An hour circle adorned with a finely crackled enamel surface carries black-enameled Breguet numerals.
This piece is powered by the caliber 17’’’ PEND mechanical movement rewound by an electric motor.
