The Da Vinci IW4523-05 (aka: 4523-05, IW452305), seen from the bench

The IWC Da Vinci IW4523-05 is an automatic timepiece featuring the IWC caliber 30130 movement with hours, minutes, seconds and date display. The stainless steel case measures 35.60mm in diameter with a distinctive asymmetrical tonneau shape, positioning it in the midsize category. This model requires a 20mm lug width for proper fitment, a specification critical to maintaining the watch's proportions and visual balance on the wrist.
