Da Vinci Watches
Concrete source of inspiration for the watch creators to give birth, in 1985, to the Da Vinci family of IWC was Leonardo's sketch for a circular bastion based on concentric fortification rings, with moats of water between the rings. But not only is it unique the unmistakable design of these IWC watches, but also their interior: with perpetual calendar with moon phases, the IWC Da Vinci watches have been created in a way that the 5 indicators (day, day of the week, month, four-digit year and moon phase) go on with a single synchronized movement. And will go on for the next generations, so far, until 2499.
