IWC Schaffhausen - Portugieser Constant-Force Tourbillon Edition “150 Years”

IWC Schaffhausen Portugieser Constant-Force Tourbillon Edition “150 Years”

A technical highlight of the Jubilee collection, this timepiece combines a constant-force tourbillon with a simple moon phase display.

IWC Schaffhausen unveiled five limited-edition Portugieser models at the Salon International de la Haute Horlogerie (SIHH) in Geneva as part of the Jubilee collection to celebrate the company’s 150th anniversary: a Constant-Force Tourbillon, two Perpetual Calendars, including one with tourbillon, a chronograph and a hand-wound model.

Today, we present the Portugieser Constant-Force Tourbillon Edition “150 Years” which is one of the most technically sophisticated watches in the collection. It combines a constant-force tourbillon with a simple moon phase display for the very first time thanks to its new IWC-manufactured 94805 calibre. Offering a 96-hour power reserve, this hand-wound movement has a patented constant-force mechanism that 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 allows for an exceptionally high level of precision. The simple moon phase display only needs to be adjusted by 1 day after 577.5 years.
