Swiss luxury watch brand Vacheron Constantin, which recently celebrated its 250th anniversary, on Sept. 7 officially opened its new international headquarters and workshops on a 30,000-square-meter site in Plan-les-Ouates, just outside Geneva, Switzerland. The modern facility, which can house up to 250 craftsmen, features state-of-the-art production facilities.

The watch firm held an open house three days earlier for families of its staff. The glass-sided building—which Claude-Daniel Proellochs, chief executive officer of Vacheron Constantin, called “luminous and transparent”—has been fully operational since August 9.

The new facility reportedly cost almost $28 million (35 million Swiss francs) and required 19 months to build. The watch company has two other sites—its research and development workshops and movement production facility, in the Vallee de Joux, and the historical site, “En L’lle,” housing the company’s museum and boutique.
