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. Demonstrating the collection's sportier side, this Yacht Club Chronograph version is powered by a 89361-calibre movement and features a flyback function, as well as quarter-second calibration for stop times that are shorter than a minute.
