The IWC Portugieser Perpetual Calendar 5021 was introduced in 2003, pairing IWC’s self-winding 7-day movement with Kurt Klaus’ ingenious perpetual calendar module. The latter was first seen in the 1985 Da Vinci and adapted to fit the larger dimensions of the 7-day movement. It featured a case of 44.2mm with sapphire glasses both front and back. One of its signature elements was the ‘Double Moon’ moonphase display, allowing its owner to read the moonphase in both the southern and northern hemisphere. The 5021 was accompanied by the slightly smaller 5022 (‘Single Moon’) in 2006. This reference, the 5021-09, features a platinum case with silver dial. It was introduced in 2003. Between 2003 and 2005 the 5021-09 had the 50611 calibre. This changed between 2005 and 2017 when it was powered by the 51612 calibre and finally by the 51614 calibre between 2007 and 2008.

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.
