This replica Portuguese IW501701 delivers the core Portugieser Automatic experience in a 42,4mm case that many consider the foundational reference of the modern seven-day power reserve range. Built by IWC, The IW501701 was among the first to introduce the updated case proportions and the Caliber 52000 series movement that now runs across the entire 501xxx family. Its dial layout follows the established Portugieser formula: prominent Arabic numerals, a railway minute track inherited from the 1930s original, small seconds at nine, and a power reserve display at three.

Key Specifications

• Case diameter: 42.4mm
• Case material: stainless steel, polished
• Dial: Arabic numerals, small seconds at 9, power reserve at 3
• Movement: automatic with 7-day power reserve
• Crystal: domed sapphire
• Caseback: transparent exhibition window
• Strap: alligator leather with folding clasp

The subdial placement at 9 and 3 gives the face a horizontal symmetry that the chronograph models, with their 12-and-6 layout, do not share. This bilateral arrangement is a signature of the Portugieser Automatic sub-family.

Design & Finishing

The Portugieser Automatic IW501701 sits at the starting point of the modern seven-day range, making it the default reference that subsequent variants build upon through different dial colors and strap combinations. The polished steel case reflects light cleanly and reinforces the dress-watch positioning. Thin lugs taper toward the strap connection, helping the 42.4mm case sit flatter than its diameter would suggest. For a dial variation within the same movement family, take a look at the Salmon Dial IW358313, which uses a 40mm case for a more compact wrist presence. Both are part of the Portuguese lineup but serve different sizing needs.

On the Wrist

The IW501701 wears slightly smaller than its 42.4mm measurement implies, thanks to the curved lugs and moderate thickness. On wrists between 6.75 and 8 inches the proportions feel natural, with the slim bezel framing the dial without excess material. The alligator strap develops character with wear and softens over the first few weeks. As the foundational seven-day Portugieser, this reference sets the baseline that every sibling variant measures against. This replica Portuguese IW501701 puts that baseline within reach for enthusiasts building around the seven-day automatic platform.
