At SIHH 2015 this week, Vacheron Constantin revealed the first Métiers d’Art Arca table clock from the 12 piece series they will produce and progressively unveil throughout the year. Each piece will be unique.

Four will utilize rock crystals, and the other eight will use translucent crystals, which are all sought out and meticulously hand-selected based on specific clarity and quality requirements.

While each crystal will be unique, all 12 clocks will use the same, new Vacheron Constantin movement comprising a constant-force mechanism and a 30-day power reserve.

Interestingly, Vacheron Constantin states that the Arca is the result of a collaboration between stone-hunters and stone-cutters, guillocheurs, engravers, and enamelists.
