A flagship complication in the Portugieser line, this IW502107 brings IWC's calendar-focused watchmaking into a 42mm yellow gold case with classical proportion and presence. Its silver dial gives the perpetual calendar displays, moonphase, and power reserve a clean, orderly canvas without losing the collection's formal character. Automatic winding adds practical ease to a watch defined by mechanical substance. At 15.5mm thick, it wears with the broad, composed stance collectors expect from a perpetual calendar Portugieser.
