At the crossroads of contemporary art, architecture and engineering, Franc Vila’s Esprit Unique makes another very strong statement. Even more impressive than the aesthetic quest for pure refinement is its technical prowess. This timepiece, with its differential gears system, houses a flying tourbillon made of lightnium, a new alloy of lithium and aluminium, and is offered in a limited edition of 8. The structured design of this mechanism has its roots in modern architecture and, as lightnium is an extremely light material, the mechanism has been pierced.
