perpetual calendar that displays day, date, month, full century, and phases of the moon, all animated by a highly precise selfwinding movement that enables full adjustment of the calendar via the crown. This highly technical timepiece is considered an absolute classic amongst complicated mechanical watches, and is credited with renewing much interest in fine watchmaking at a time when quartz watches threatened the traditional craft of mechanical horology. The stainless steel or 18K rose gold case of the IWC Da Vinci watch is perfectly crafted, its round contours and pushpieces projecting a sense of visual calm, that contrast strikingly with the elaborate wealth of information presented on the dial.
