The Da Vinci IW4523-23 (aka: 4523-23, IW452323), seen from the bench

The IWC Da Vinci IW4523-23 is a 35.60mm rose gold automatic watch introduced in 1985, featuring the in-house IWC caliber 30130 with approximately 42 hours of power reserve. The case combines classical proportions with integrated lugs and includes a big date window, sapphire crystal with anti-reflective coating, and 30 meters water resistance. The 20mm lug width is calculated to maintain visual harmony with the case diameter, making this midsize model a refined dress watch rather than a sports instrument.
