Introducing IWC Da Vinci (ref. IW4523-31), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in white gold and measuring 35.6 mm in diameter, with a thickness of 10.9 mm, defined by a tonneau silhouette, paired with a gem-set bezel. The caseback is closed, and the crystal is sapphire, delivering water resistance to 1000 meters. At a glance, the dial balances texture and clarity: a black tone, framed by gem-set indexes hour markers, and alpha hands. At its heart beats a proven engine: the 30130 caliber. Initial production year: 20092009. 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.
