The Basics

IWC introduced its perpetual calendar mechanism for wristwatches in 1985 in the Da Vinci reference 3570. It was a spectacular novelty at the time. Critically acclaimed and powered by its price that shook the industry, the module would grow out to be the most widely sold perpetual calendar mechanism – not only fitted to the Da Vinci collection, but in adapted form in the Novecento, the GST, the Pilot’s Chronograph and various models by JLC, including the current Master Ultra Thin Perpetual . It would also serve as the base for the IWC’s Grande Complication and their masterpiece of the time, the spectacular Destriero Scafusia. The ref. IW9253-001 has a case of yellow gold with diamond-set bezel and lugs, a matching bracelet and a white dial with German markings. Sapphire glass was available at request while plexi was the standard option.

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.
