Its refined design features improved construction with thinner casing rings and double box-glass sapphire crystals. The intricately crafted dial, with 15 layers of lacquer, automatically adjusts for month lengths and leap years, with displays synchronized via a single crown. The IWC 52616 caliber movement ensures a seven-day power reserve, driven by an automatic Pellaton winding system with wear-resistant ceramic components and a solid gold oscillating mass. The watch comes with a black alligator leather strap from Santoni, featuring an 18-carat white gold folding clasp.
