Drawings were made of the proposed new watch, reflecting a painterly artistry. These drawings reveal a watch that for its era had distinctive characteristics: the stepped bezel, pushers with rounded heads and, of course, the distinctive lugs. This was intended to be a watch that was both classical and revolutionary, moving forward in a futuristic way but with great tradition: This design reflected a tradition not just of watchmaking, but also Italian renaissance design.
Da Vinci was a fitting name for this special watch, with its special perpetual calendar and chronograph mechanism, and its unique design.
The Da Vinci Perpetual Chronograph was, in fact, the beginning of a renaissance for IWC. In the dark ages of mechanical watches, this new model, Reference 3750, created a rebirth for IWC and indeed in many ways the entire Swiss mechanical watch industry. It was the first new perpetual calendar produced in many years, and soon IWC become a leader of a reborn industry. IWC became noted, even more than before, for its engineering prowess. Hanno Burtscher’s distinctive design become an iconic symbol of IWC.
In addition to the Da Vinci drawings, Herr Burtscher, very much the artist, also made drawings of several other watches, including IWC Portuguese models. Several of the senior members of IWC have collected original prints of these or the original drawings. There even are a few displayed in offices in Schaffhausen.
