It is exactly this year that IWC’s legendary Portugieser celebrates its 75th anniversary. Its birth is the result of a special request by two Portuguese businessmen asking IWC to produce them wristwatches performing at the level of marine chronometers. The only possibility to achieve this task was to use a pocket watch movement, the firm’s in-house calibre 74. The present example, cased in white gold, is the newest version featuring a perpetual calendar. Hardly ever worn by the original owner, it is complete with all accessories delivered when purchased new.
With a clear focus on technology and development, the Swiss watch manufacturer IWC Schaffhausen has been producing timepieces of lasting value since 1868. The company has gained an international reputation based on a passion for innovative solutions and technical ingenuity. One of the world's leading brands in the luxury watch segment, IWC crafts masterpieces of haute horlogerie at their finest, combining high precision with masculine design. Vintage wristwatches such as the oversized Portugieser, Aquatimer, Ingenieur and the B-UHR pilots watch are especially desirable for collectors.
