Portugieser Chronograph

The Portugieser Chronograph's whole identity comes from a spec sheet that says the movement is a 7750 base while the watch on the wrist reads like haute horlogerie. For 22 years IWC ran the same worked ETA caliber under a dress-watch dial and let the case, the printed railroad track, and the blued leaf hands do the talking, and it outsold everything else the brand made. When IWC finally brought the manufacture caliber 69355 in 2020, some longtime owners argued the old 79350 was the more honest watch: bulletproof, cheap to service, and finished under a solid caseback where nobody was pretending. That debate is exactly why both generations hold value. Also worth knowing: the model was born Portuguese and became Portugieser in the 2020 relaunch, so paperwork and dials can carry either name depending on year, and neither spelling is a red flag. The original inspiration traces back to two Portuguese businessmen in the late 1930s who wanted marine-chronometer accuracy on the wrist, which is why the whole line runs oversized and clean-faced decades before that was in style.
