Introduction
The IWC Portuguese 7-Day Power Reserve (IW500715), often referred to as the "Portugieser Automatic" or "Portuguese 7" (or simply "Portu 7"), is one of the most iconic dress watches from IWC Schaffhausen. Known for its clean, elegant dial design and impressive 7-day power reserve, it has been a favorite among watch enthusiasts for years.In the replica world, ZF Factory has long been a dominant player, producing some of the most accurate clones of luxury watches. Their latest 2025 V5 upgraded version of the IWC Portuguese 7 promises even better refinements over previous iterations. Today, we’ll take a deep dive into this watch, examining its case, dial, movement, and overall accuracy compared to the genuine model.
1. Case & Build Quality
The ZF V5 Portuguese 7 retains the 42.3mm case diameter, matching the original IWC dimensions perfectly. The case is crafted from 316L stainless steel, with a combination of brushed and polished surfaces that give it a high-end feel.- Case Thickness: One of the biggest concerns with the Portuguese 7 is its thickness (14.1mm on the gen). ZF has managed to replicate this almost identically, ensuring the watch wears similarly to the authentic model.
- Lugs & Crown: The lugs are slightly curved for better wrist comfort, and the screw-down crown features crisp engravings of the IWC logo.
- Sapphire Crystal: The watch uses a double-sided AR-coated sapphire crystal, reducing reflections and improving legibility. The blue anti-reflective coating is subtle but effective.
Comparison with Genuine:
- Case Finish: The brushing and polishing on the ZF version is nearly indistinguishable from the gen.
- Weight: The replica is slightly lighter due to the movement construction, but the difference is minimal.
2. Dial & Hands – The "Panda" Aesthetic
The IW500715 features the classic "Panda" dial—a white base with blue subdials at 9 o’clock (small seconds) and 3 o’clock (power reserve indicator).Key Dial Features:
- Sunburst White Dial: The texture and color are very close to the gen, with a slightly creamy off-white tone rather than pure white.
- Blue Subdials: The color matching is excellent, with a deep, rich blue that changes slightly under different lighting.
- Applied Numerals & Markers: The 3D Arabic numerals are well-executed, with blue accents that match the hands.
- Date Window: The beveled date window at 6 o’clock is correctly positioned and features a white date wheel with black printing (just like the gen).
Hands & Lume:
- Blued Steel Hands: The heat-treated blue hands have a slight gradient effect, similar to the original.
- Lume: The lume application is decent but not as strong as the gen. The markers and hands glow faintly in the dark.
3. Movement – The Custom "Cal.52010" Clone
The biggest upgrade in the ZF V5 is its customized automatic movement, designed to mimic the IWC Cal.52010.Movement Specifications:
- Power Reserve: The genuine Cal.52010 offers 7 days (168 hours) of power reserve, while the ZF version provides around 3-4 days (72-96 hours)—still impressive for a replica.
- Decoration: The movement features Geneva stripes, perlage, and blued screws, closely resembling the gen.
- Functionality:
- Small seconds at 9 o’clock
- Power reserve indicator at 3 o’clock
- Date function at 6 o’clock
Comparison with Genuine:
- Rotor Noise: The ZF rotor is quieter than earlier versions but still slightly louder than the gen.
- Accuracy: The movement runs at 28,800 vph (4Hz), matching the gen’s beat rate.
4. Strap & Clasp
The watch comes with a high-quality blue leather strap, though it’s not as supple as the genuine IWC alligator strap.- Deployant Clasp: The folding clasp is well-made, with IWC branding and a smooth operation.
- Upgrade Option: Many owners replace the stock strap with an aftermarket alligator leather strap for a more premium feel.
