IWC Ingenieur Perpetual Calendar Digital Date-Month Titanium

It's one of their most complicated timepieces and also one of their most striking. The Ingenieur Perpetual Calendar Digital Date-Month sports two large digital displays that indicate the date and month, both of which are mechanically programmed to know the specific lengths of each month and can add a leap day at the end of February every four years. This is all made possible by their in-house manufactured 89801 caliber automatic movement that also features a chronograph with flyback function and has a 68 hour power reserve. This new edition of the watch lightens the load a bit with a 45mm case that is now fully rendered in grade 5 titanium. 

The Ingenieur Perpetual Calendar Digital Date-Month is now available in a limited run of 100 pieces.
