IWC Portuguieser PIC crop

Introducing the “Portugieser Annual Calendar” which is a new alias for a model traditionally designated as part of the “Portuguese” collection, as IWC had branded it until now.

But, the newest IWC edition is more than just a moniker. It features a remarkable new layout and debuts a new movement in-house made by IWC, caliber 52850, which has two mainspring barrels instead of one. The extra barrel adds the additional torque required to move the various discs that display the calendar information, as well as the subsidiary seconds dial and power reserve indicator, while still operating at a rate of 4Hz (28,800 bph).

The dial comes in two different colors to choose from:”Midnight Blue” or “Silver-Plated”.

Although only the latter will be available in both a steel or an 18k red gold case, while the “Midnight Blue” is only available in steel.

Its 44.2mm wide case size seems appropriate, but the 15.3mm thickness is what really seems to make this watch look bulky. The crystal over the dial is also doomed and not flat, which adds more to the overall thickness. While the sapphire crystal exhibition caseback manages to reveal some of “Portugieser Annual Calendar’s” inner beauty and innovations.

All the calendar and time adjustments will be done via the crown, which means no inset case pushers. This can only become a hassle if the watch was to run out of wind many times, but its long 7-day power reserve (168 hours) should prevent such a complication.

It is however a annual watch and will need to be adjusted every February and leap years, unlike perpetual calendars. But they also differ favorably on the price-tag in comparison to those models, so that can be seen as a positive aspect.
