In 2007 Vacheron Constantin introduced the Metiers d’Art Les Masques collection of timepieces featuring the miniature reproductions of primitive art masks.

This year sees the launch of the third and final set (limited like the others to a 4 piece set of 25).

The timepieces are inspired from artwork found in the Barbier-Mueller collection - a collection of over 7,000 pieces which includes artwork from tribal, classical and other primitive civilizations from around the globe.

For this new collection, the watches have been inspired from four new historic cultures.

We have the pictured mask from China, as well as masks from Indonesia (Oceania), Gabon in Africa, as well as from Mexico.

The miniature masks are created by scanning the originals to get a three-dimensional image, then a prototype was given to an engraver who meticulously carved the masks to replicate the exact look of these ancient artifacts.

Each of the four watches is produced from a different metal - yellow gold, white gold, pink gold and platinum.

The miniature masks appear upon a transparent sapphire crystal, and each watch is engraved with a poem by French writer Michel Butor.
