About IWC

IWC logo

IWC is based in Schaffhausen, Switzerland, and was founded in 1868. Its signature lines are the Pilot’s Watches and the Portugieser, while other famous collections are the Aquatimer, Portofino and the Da Vinci. Many of IWC’s designs display a industrial type of beauty not often found in Swiss watchmaking. The same goes for its movements; while of very high standards, they are finished with an … engineers touch rather than that of an artist. One could very well say that IWC’s approach to watchmaking is more German in nature compared to many of its competitors; the ‘form follows function’ adagio is one held in high esteem in Schaffhausen. Notable watches and innovations created by IWC in the past include the digital ‘Pallweber’ pocket watch, the late 1930’s Portugieser, the 1985 Da Vinci with Kurt Klaus perpetual module, the split-seconds mechanism as designed by Richard Habring and the ceramic Da Vinci and Flieger 3705 – introduced many years before the material became fashionable. IWC also pioneered the use of titanium in wristwatches. In recent years, IWC has had a strong focus on in-house movements with prices rising accordingly. IWC is part of the Richemont group.
