SIHH 2015: Metiers d'Art Acra - Rock Crystal T
Vacheron Constantin can now look back on 260 years of uninterrupted creative activity and is celebrating this milestone by a sparkling tribute to the decorative arts that have significantly contributed to its enduring success. A collection of 12 unique crystal table clocks resembling luminous arches is one of the means by which Vacheron Constantin is demonstrating the twin mastery of Haute Horlogerie and artistic crafts for which it has become a prominent ambassador over successive generations.
The 1st of the Arca models to be presented in the Rock Crystal. This clock - inspired by a handful of table clocs made by vacheron Constantin in the 1930s feaures a the brand new manufacture movement Cal 9260 with a 30 day power reserve and a remarcable constant force escapement (which enables the power given to the bbalance via the mainspring to be equally distributed may the watch be fully wound or near the end of its power reserve - thus providing greater accuracy).
Furthermore, above and beyond the work on the crystal, two decorative techniques are particularly in the spotlight on the chapter ring and the feet of each table clock: Grand Feu enamelling and guillochage. The 12 satin-brushed silver Roman numerals have been individually crafted and then coated with black Grand Feu enamel. This delicate stage requires finely controlled operations, since the melting point of enamel is 860°C,
The facetted silver feet supporting the table clock feature 12 unique hand-guilloché motifs that shimmer with the translucent colours of Grand Feu enamel. Since each foot is an all-of-a-piece construction, the guillocheur has had to extend the décor to five faces, thereby considerably increasing the difficulty of creating the motifs. A fresh challenge that requires the master-artisans to perpetually reinvent their dexterity. For more information
