IWC Schaffhausen showed significant new watches and movements on the first day of the Salon International de la Haute Horlogerie (SIHH) in Geneva as part of the Jubilee collection celebrating the company’s 150th anniversary. The five-model, limited-edition Portugieser, is now showing at SIHH. The Portugieser Constant-Force Tourbillon Edition “150 Years” is one of the most technically sophisticated in the collection and combines a constant-force tourbillon with a simple moon phase display for the very first time. IWC is also launching a Portugieser with a perpetual calendar in the design of the Jubilee collection and fitting the Portugieser Chronograph with an IWC-manufactured calibre. An anniversary edition of the Portugieser Hand-Wound is also being launched. Their distinguishing features are the dials produced using a complex lacquering process in white or blue.

Portugieser Perpetual Calendar Tourbillon Edition «150 Years»
With the Portugieser Perpetual Calendar Tourbillon Edition “150 Years” (Ref. IW504501), IWC combines a perpetual calendar with a tourbillon on the dial for the first time. This is made possible by the newly developed IWC-manufactured 51950 calibre, an extension of the 51900 calibre. Made of 82 individual components and weighing just 0.635 grams, the tourbillon is visible at “12 o’clock”, with an integrated the moon phase in the month display disc at “6 o’clock”. A solid gold rotor allows the automatic winding system to generate a power reserve of seven days. Limited to 50 pieces: 18-carat red gold, white dial with lacquered finish, blued hands.
Portugieser Constant-Force Tourbillon Edition «150 Years»
IWC considers the Portugieser Constant-Force Tourbillon Edition “150 Years” (Ref. 5902) a technical highlight of its Jubilee collection. Just 15 of each of the two models will be made: platinum, white dial with lacquered finish, blued hands; and, platinum, blue dial with lacquered finish, rhodium-plated hands. 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 simple moon phase display that only needs to be adjusted by 1 day after 577.5 years. The patented mechanism is described as "constant-force" because it is said to "transmit completely even impulses to the escape wheel". In conjunction with the tourbillon, which compensates for the earth's gravitational pull on the watch’s oscillating system, it results in "an exceptionally high level of precision".

Portugieser Perpetual Calendar Tourbillon Edition «150 Years»
A special interpretation of this classic watch, in the design of the Jubilee collection. Production is limited to 250 pieces. The IWC-manufactured 52615 calibre with Pellaton winding generates a power reserve of seven days with a solid-gold rotor and two barrels. The perpetual calendar automatically recognises the differing lengths of the months as well as leap years and will require no adjustment until the year 2100. The double-moon display depicts the moon as a mirror image that is correct for both the northern and southern hemispheres and that will only deviate by one day from the actual cycle of the earth’s satellite after 577.5 years.
