This replica Portuguese IW501704 takes the 42.4mm Portugieser Automatic case and pairs it with a dial configuration that leans toward the warmer end of the Portuguese color spectrum. The IW501704 reference is part of the same automatic family as the IW501701, IW501702, and IW501708, sharing identical case dimensions and movement architecture while differentiating through dial color and strap treatment. IWC has historically used the Portugieser Automatic as a canvas for chromatic variety, and this reference continues that approach.

Technical Overview

• Case diameter: 42.4mm
• Case material: stainless steel with polished surfaces
• Dial layout: Arabic numerals, small seconds, power reserve indicator
• Power reserve: 7-day architecture
• Crystal: domed sapphire with anti-reflective treatment
• Caseback: transparent for movement viewing
• Strap: leather with deployment buckle

The 42.4mm case diameter paired with relatively short lugs gives this Portugieser a wrist presence that feels proportionate rather than oversized. The polished finishing on the case sides catches light cleanly and adds formality to the overall profile.

Inside the Movement

The genuine IW501704 houses the Caliber 52010, a Pellaton-wound automatic movement with a 7-day power reserve and stop-seconds function. This extended power reserve means the watch can sit unworn for nearly a full week before losing time, a practical advantage for rotation wearers. The exhibition caseback reveals the movement architecture, including the double-barrel system that stores the energy needed for that seven-day run time. For a blue-dial alternative within the Portugieser automatic range, the Portuguese 40mm Blue Dial IW358305 offers a smaller case size with a different movement. Both come from the Portuguese family but address different sizing preferences.

What Sets It Apart

Among the 42.4mm Portugieser Automatics, the IW501704 distinguishes itself through its specific dial-and-strap pairing. The warm dial tone gives it a character that contrasts with the cooler blue and slate options in the same reference range. For buyers building a collection around IWC Portugiesers, this reference fills a different visual role than its siblings while maintaining the same mechanical foundation. This replica Portuguese IW501704 brings that warm palette into reach for anyone expanding their Portuguese automatic rotation.
