It features the sophisticated IWC 51900 calibre with visible tourbillon, a clean dial with Breguet hands, small seconds, date window, and a power reserve indicator displaying up to 7 days of autonomy. The 18mm lug width is specifically calibrated to match the case proportions and horn design for seamless aftermarket strap integration.
