This replica Portugieser IW501708 presents a 42,4mm stainless steel case from the Portugieser Automatic family, a line that highlights clean dial design and extended power reserves within the Portugieser collection. The IW501708 reference features a distinctive dial built around the Portugieser’s signature slim-bezel proportions that let the dial occupy nearly the entire visual footprint. IWC’s approach to the automatic Portugieser has always favored legibility over complication density, and this reference continues that philosophy with an uncluttered face and prominent Arabic numerals.

Key Specifications

Design & Finishing

The Portugieser Automatic at this size occupies a middle ground between dress watch and everyday wearer. Thin lugs allow it to hug the wrist more closely than the case diameter might suggest, and the domed sapphire crystal adds a subtle curve to the dial view that flat crystals lack. The railway-style minute track around the outer edge is a heritage detail carried forward from early Portugieser models dating to the 1930s. To see how this size translates into a gold-tone configuration, check the Automatic Gold Dial IW501705 from the same Portugieser range.

On the Wrist

The 42.4mm case with slim lugs wears well on wrists from 6.5 to 8 inches. Unlike thicker chronographs that sit high, the Portugieser Automatic keeps a relatively low profile. The leather strap complements the dressy tone without locking the watch into purely formal territory. This replica Portugieser IW501708 suits anyone looking for a Portugieser that balances presence with wearability across varied settings from office to weekend.
