The origins of the Portugieser date back to the late 1930s, when IWC Schaffhausen used a high-precision pocket watch movement to create a distinctively large wristwatch with chronometer precision. First introduced in 2000, the Portugieser Automatic 42 features an open, balanced dial, with a power reserve indicator at 3 o’clock and the small seconds positioned on the opposite side at 9 o’clock.
