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.
