The Portugieser Constant-Force Tourbillon Edition “150 Years” Story

The Portugieser Constant-Force Tourbillon Edition “150 Years” stands out as one of the technical highlights in the jubilee collection. This model has a platinum case, a blue dial with a lacquered finish, and rhodium-plated hands. It is available in a limited edition of just 15 watches. For the first time, the new IWC-manufactured hand-wound 94805 calibre, with a power reserve of 96 hours, combines a constant-force tourbillon with a single moon phase display. This moon phase display needs to be adjusted by only one day every 577.5 years. The patented constant-force mechanism disengages the escapement from the direct flow of power from the wheel train, and 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 a very high level of precision.

Calibre Family 94000

The hand-wound movement features two barrels including the constant-force tourbillon, the astronomical module in the Portugieser Sidérale Scafusia and the digital Pallweber display.

Moon phase display

IWC’s moon phase displays are not just aesthetic works of art – they are extremely precise and diverge from the actual phase of the moon by just 1 day in 577.5 years.

Constant-force tourbillon

With the patented constant-force tourbillon, IWC elegantly combines two complications that serve to increase timekeeping precision.
