Introducing the IWC Portuguese Perpetual Calendar Digital Date 75th Anniversary Edition


Carrying on the 75th anniversary of its Portuguese family, here we have the Perpetual Calendar Digital Date-Month from IWC. The watches’ name is very appropriate, as it describes the watch itself pretty accurately. If the Hand-Wound is a contemporary throwback, the Perpetual Calendar is a modern adaptation of recent design trends seen in the Portuguese family. Even though the digital date and month display is popular with IWC, this is the first time they’ve used it in the Portuguese line.




It contains a recognisable complication set, in fact, just last year we saw this very same movement come packaged in an oversized Aquatimer limited edition.

The new Perpetual Calendar gets outstanding digital display apertures to display the month and the date, IWC’s use of this dates back to 1884. It’s a handsome display technique, and it’s something we’ve seen before from the likes of A. Lange & Söhne to great effect. Unlike Lange, however, IWC has chosen to label the apertures with “date” and “month.” Aligned vertically on the dial are dual sub-dials, housing the chronograph timing hands at 12 o’clock, and the running seconds at 6 o’clock, which also includes the leap year indication.

A great bonus of the IWC’s caliber 89801 is how simple it is to set and work, as it’s all done via the crown. You don’t need to adjust anything until the year 2100, this is thanks to the movements prenominal precision. Another feature is that the movement is visible through the exhibition case back. It is offered in both platinum and red gold. The red gold will give you the choice between a silver-plated or grey dial. Just 25 examples will be built in platinum, while the red-gold variants will be limited to 75 examples.
