Portugieser Automatic 40

The IWC Portugieser Automatic 40 brings the classic elegance of the Portugieser line into a more wearable 40.4mm case, echoing the proportions of the original 1930s reference commissioned by Portuguese navigators. This model is prized for distilling the timeless dial layout—railway minute track, applied Arabic numerals, and small seconds at 6 o’clock—into a size that suits a wider range of wrists without losing the model’s signature presence.

The key reference here is the IW3583 series, introduced in 2020, which houses the in-house caliber 82200 automatic movement with a Pellaton winding system and 60-hour power reserve. Variants differ mainly in case material—stainless steel or 18k gold—and dial color, with silver-plated and blue versions being most sought after. Gold models command a premium, but even within steel, prices can vary based on dial rarity and condition.

When considering a Portugieser Automatic 40, inspect the movement’s finishing through the display caseback and check for original box and papers, which add value. Earlier Portugieser automatics were larger (42mm+), so this 40.4mm edition is especially desirable for those who appreciate the line’s heritage in a more versatile format. The 30m water resistance suits dress occasions rather than sport, and the slim profile wears comfortably under a cuff.
