The origins of the Portugieser date back to the late 1930s, when IWC Schaffhausen used a high-precision pocket-watch movement to create a particularly large wristwatch with chronometric accuracy. Introduced in 2000, the Portugieser Automatic 42 features an open and well-balanced dial, with a power-reserve indicator at 3 o’clock and a small-seconds display opposite it at 9 o’clock.
