From IWC, presenting the Da Vinci (ref. IW3921-04), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in platinum and measuring 43 mm in diameter, with a thickness of 15.5 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a silver tone with matte finish, framed by arabic numerals hour markers, and dauphine hands. At its heart beats a proven engine: the 89630 caliber. Issued as a limited edition, appealing to focused collectors. First released in 2017. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
