Pre SIHH 2018: IWC Portugieser Jubilee Collection «150 Years»

Portugieser Constant-Force Tourbillon Edition «150 Years»

The IWC Portugieser Constant-Force Tourbillon Edition «150 Years» also stands out in the Jubilee collection. The watch has a “46mm” platinum case, a white dial with a lacquered finish, and blued hands. It is available in a limited edition of 15 pieces. For the first time, the new manufactured hand-wound 94805 calibre with a power reserve of 96 hours combines a constant-force tourbillon with a single moon phase display that only needs to be adjusted by 1 day after 577.5 years. The patented constant- force mechanism transmits completely even impulses to the escape wheel. In conjunction with the tourbillon, which compensates for the negative influences of gravity on the watch’s oscillating system, this achieves an exceptionally high level of precision. (Price about €.255.000)

Portugieser Perpetual Calendar Tourbillon Edition «150 Years»

With the IWC Portugieser Perpetual Calendar Tourbillon Edition «150 Years», IWC combines a perpetual calendar with a tourbillon on the dial for the first time. This spectacular watch has an 18-carat “45mm” gold case, a white dial with a lacquered fnish, and blued hands. It is available in a limited edition of 50 watches. The watch is driven by the newly developed manufactured 51950 calibre. This is an extension of the basic 51900 calibre, with the addition of a perpetual calendar. The tourbillon is visible at 12 o’clock because the watch designers opened up the calendar advance ring and integrated the moon phase in the month display disc at 6 o’clock. With its solid gold rotor, the automatic winding system generates a power reserve of 7 days. (Price about €.110.000)
