Exclusively available in Mexico in a 5-piece limited edition, the Vacheron Constantin Patrimony Traditionnelle World Time Mexico Limited Edition follows the steps of the Vacheron Constantin Patrimony Traditionnelle World Time Unique Piece that was created for Mexico's National Institute of Anthropology and History —INAH— back in 2013. The INAH Unique Piece was auctioned during the SIAR 2013 at a gala dinner in Mexico City with all proceeds going to the INAH in order to continue to support and promote the recovery of the national heritage of Mexico.
