The IWC Portugieser Chronograph IW371617 continues the legacy of the original 1939 Portugieser, created at the request of Portuguese navigators who demanded exceptional precision. The large, clean dial with Arabic numerals and railway-track minute scale remains as elegant today as it was over eight decades ago.
The Calibre 89361 is a self-winding column-wheel chronograph movement based on the Pellaton winding system, offering a 68-hour power reserve. The integrated flyback chronograph function allows instant reset and restart with a single push.
The Portugieser Chronograph is the standard against which all other classic chronographs are measured. Its proportions, its dial legibility, and its movement quality represent the very best that Schaffhausen has to offer.
