n 2009 IWC created the Da Vinci Perpetual Calendar Digital Date-Month (ref. 3761). It was the first flyback chronograph with a perpetual calendar and digital leap year display as well as a digital display for the month and date with large numerals. This development was a tour de force that has paid off: the result is a very clever way to combine a perpetual calendar and a chronograph, while maintaining the legibility of all functions. Monochrome goes hands-on with the IWC Ingenieur Perpetual Calendar Digital Date-Month.http://monochrome-watches.com/iwc-ingenieur-perpetual-calendar-digital-date-month/?utm_source=feedburner&utm_medium=twitter&utm_campaign=Feed%3A+monochrome%2FBwOB+%28Monochrome-Watches.com%29
