With the Portugieser Perpetual Calendar Tourbillon Edition “150 Years”, IWC combines the legendary perpetual calendar created by Kurt Klaus with a tourbillon on the dial for the first time. This masterpiece of watchmaking is available in a limited edition of 50 watches. It has an 18K red gold case, a white dial with a lacquered finish, and blued hands. To make the tourbillon visible at 12 o’clock, the designers opened up the calendar advance ring and integrated the moon phase in the month display at 6 o’clock. This tourbillon complication is made up of 82 individual components and weighs just 0.635 grams.
With a tourbillon 'mystère' concept that fascinates thanks to the unusual arrangement of its “flying” tourbillon against a deep black background, the complication creates the illusion that the filigree cage containing the balance is rotating in mid-air.
The watch is powered by the in-house IWC 51950 calibre, an extension of the 51900 calibre with the addition of a perpetual calendar. This 44-jewel automatic movement beats at a frequency of 19,800 vph to provide a power reserve of 7 days —168 hours.
On the wrist, the new Portugieser Perpetual Calendar Tourbillon Edition “150 Years” wears slightly larger than its actual case size and more like a 47 mm watch. Without a doubt one of the most impressive watches from IWC and a treat for the eyes.
