The Da Vinci Automatic 36 (Ref. IW458307/IW458308/ IW458310/IW458312) and the Da Vinci Automatic Moon Phase 36 (Ref. IW459306/IW459307/IW459308) are not only smaller and slimmer, but also have a more feminine design: with rounded crowns and a recessed inner circle on the dial, as previously found in the Portofino 37 mm collection. Gold cases, diamond-set bezels and alligator leather straps by Santoni in the colours raspberry, bronze, dark brown and dark blue specially developed for IWC underscore the watch’s aesthetic appeal. To achieve the nuanced gradations of colour on the strap, the surface of the leather is polished with a variety of different pastes until it has the desired shading and a perfect sheen. As a result, every strap has an exclusive patina-like shimmer with its own individual nuances of colour. The moon phase display, which has been part of the Da Vinci family since 1985, is now the visual centre of the silver-plated dial in the Da Vinci Automatic Moon Phase 36. The gold- or silver-coloured moon moves clockwise against the dark blue night sky. The so-called “Flower of Life” is engraved on the case backs of all Da Vinci Automatic 36 and Da Vinci Automatic Moon Phase 36 models. This geometrical figure features several regularly overlapping circles and was the object of intensive study and numerous drawings by Leonardo da Vinci. It represents his unflagging search for mathematical rules for beauty and proportions, and thus symbolizes the new design approach of the watch collection.
