Ladies’ minute-repeater wristwatch with dial in cloisonné enamel over hand-executed guilloché work.

The first minute-repeater wristwatches for women to feature dials in Grand Feu cloisonné enamel, these haute horlogerie models decorated with rare handcrafts depict a bird pecking red berries.

First, the white or yellow gold dial plate was hand-guilloched with a fine panier or basket-weave pattern. Next, the enameler outlined the graceful picture of the bird with outspread wings and the branch, using 58 cm of gold wire (0.32 g) measuring 0.07 x 0.4 mm in crosssection. He then brought the scene to life with a palette of transparent, opaque and opalescent enamels in 21 colors. Each dial required 10 firings at a temperature of approximately 750°C.

The white or rose gold Calatrava-style case houses the caliber R 27 self-winding movement with minute repeater striking on two gongs. Comprising 342 parts, the movement is visible through a sapphirecrystal case back. The watches also come with an interchangeable back in solid white gold or rose gold.

Attention to details
Enameling

Enameling, often used by Patek Philippe to decorate cases and dials, is one of the most high-risk of the rare handcrafts. The precarious fusing of powdered glass at ultra-high temperatures can produce heartbreaking disasters but, when successful, the result is luminous beauty, from designs in radiant, jewel-bright colors that will never dull, to lustrous, gently traditional looks.
