IWC Launches its Flagship Perpetual Calendar Digital Date-Month

With a name this long, you know IWC isn’t kidding around. The Perpetual Calendar Digital Date-Month is the flagship watch for Swiss watchmaker IWC. Even though IWC has been around since the 1950s, this is the first time that they’ve delved into the “flagship” lineup, and they’re not holding anything back.

Inside the Perpetual Calendar Digital Date-Month, you’ll find IWC’s in-house caliber 89801. The movement is encased in a 45 mm case that is made of grade 5 titanium—the sort of titanium that is typically used for aerospace and internal combustion engines. In other words, this case is ready for any sort of abuse it may come across.

That titanium is needed for the engineering that is required to program the 89801 to compensate for different months and for a leap year every four years, not to mention the flyback chronograph complication. All those dates are displayed with large, double-digit displays for date, month, and leap year.

If you’re looking for gold in this watch, you’ll only find it in the 18k rotor. Aside from calendaring, the watch also tracks hour and minute with a chronograph with a totaliser at 12 o’clock.

Given the materials used, and the fact that this is a “flagship” watch, it shouldn’t be surprising to learn that this watch sells for USD$37,400, or that it is limited to just 100 numbered examples.
