The Portugieser's story starts in the late 1930s, when two Portuguese businessmen came to
IWC seeking wristwatches with the precision of marine chronometers. The result was a
watch that was far ahead of its time - inside and out. 75 years later, it's a style that reflects the Swiss brand's success as an internationally-renowned name in haute horology. Finished in a combination of luxurious alligator leather and sturdy stainless steel, this annual calendar version features an IWC-manufactured 52850 calibre movement with the legendary Pellaton winding system.
