This replica Portuguese IW501702 houses the Portugieser Automatic format in a 42.4mm stainless steel case, continuing the seven-day power reserve architecture that defines the modern Portuguese automatic range. The IW501702 reference carries a specific dial treatment that positions it among the more classic-leaning variants in this family. Arabic numerals, a railway-style minute track, a small seconds subdial, and a power reserve indicator fill the dial without crossing into visual clutter, a balance that IWC has refined across multiple generations of this model.

Case & Movement Specs

• Case diameter: 42.4mm
• Case material: stainless steel
• Dial features: Arabic numerals, railway minute track, small seconds, power reserve
• Power reserve: 7-day (168-hour genuine spec)
• Crystal: domed sapphire with anti-reflective coating
• Caseback: exhibition style with sapphire window
• Water resistance: 30 meters

The 30-meter water resistance keeps this firmly in dress-watch territory. It handles hand washing and rain but is not designed for submersion. The sapphire exhibition caseback exposes the Pellaton winding system and twin barrels that deliver the seven-day power reserve.

Caliber Breakdown

The genuine Caliber 52010 behind this reference uses a ceramic Pellaton winding mechanism, replacing the traditional steel components for improved longevity and reduced friction. Twin mainspring barrels work in series to deliver the 168-hour power reserve, and a hacking seconds function allows precise time setting. The automatic winding rotor uses bidirectional winding for efficient energy capture during normal wrist movement. Compare this movement platform to the perpetual calendar execution in the Perpetual Calendar IW503301, which adds calendar complications on top of a similar base architecture. Both sit within the Portuguese family but represent different levels of mechanical complexity.

How It Compares

The IW501702 shares its 42.4mm case and movement platform with the IW501701, IW501704, IW501707, and IW501708. Choosing between them is a dial-and-strap decision rather than a mechanical one, since the internal architecture remains consistent across the range. The IW501702 specifically occupies the classical end of the spectrum with its particular dial treatment and strap pairing. This replica Portuguese IW501702 delivers the full seven-day Portugieser automatic experience in a configuration that favors traditional styling over contemporary boldness.
