1. Introduction: The Legend of the Portugieser
The IWC Portugieser Automatic (Reference 5007) is an icon of modern horology. Launched in 2004 (originally as the 5001), it defined the “oversized dress watch” category. Its massive dial, rail-track chapter ring, and twin sub-dials make it instantly recognizable.
In the IWC replica world, this model is a bestseller. For a decade, ZF Factory was the undisputed king of this model. Their V5 version was considered the gold standard.
However, in late 2024, APS Factory released a new version with a shocking claim: A real integrated movement.
Is this just marketing hype? Or has ZF finally been dethroned? In this comprehensive review, we pit the APS IWC replica against the ZF IWC replica to find the truth.

2. Which Factory Makes the Best IWC Replica in 2025?
This is the most searched question among buyers looking for an IWC replica in 2025, and the honest answer is: it depends on what you value most.
If we judge purely by movement architecture and technical ambition, APS Factory currently leads the IWC replica market. Their integrated 52010-style movement represents the closest attempt yet to replicate the genuine IWC engineering concept rather than relying on decorative solutions.
However, if we judge by overall balance, long-term reliability, and visual accuracy, ZF Factory still remains one of the safest choices for an IWC replica, especially for classic white-dial Portugieser references.
In short:
- APS Factory makes the most technically advanced IWC replica available today.
- ZF Factory makes the most time-tested and visually consistent IWC replica for long-term ownership.
There is no absolute winner — only the right choice for the right buyer.
3. The Movement: 52010 Clone Wars
This is the biggest selling point of the APS IWC replica.

APS Factory (The Challenger)
- Architecture: APS built an Integrated Movement. This means the gears you see are real, not just a decoration plate stuck on top of a 7750.
- Power Reserve: APS claims 160 hours. In our real-world test, it lasted about 80-90 hours (3-4 days). While not 7 days, this is double the industry standard for an IWC replica. It is impressive.
- Noise: The rotor is quiet (below 25dB), thanks to improved bearings.
ZF Factory (The Veteran)
- Architecture: ZF uses a base movement with a decorative deck. It looks 95% like the genuine, but the internal structure is different.
- Stability: The ZF movement has been on the market for 5 years. It is a proven, reliable IWC replica engine.
4. The Case & Crystal: Thickness Matters
The genuine watch is 14.1mm thick. IWC replica manufacturers have struggled to get this right.

APS Factory
- Thickness: 13.9mm. It is actually a hair thinner than genuine, which makes it wear very comfortably.
- Crystal: APS uses a Domed Sapphire crystal with “borderless” edges. The light plays beautifully on the curve.
ZF Factory
- Thickness: 14.1mm. Identical to genuine.
- Crystal: Slightly flatter than APS. It looks great, but APS has a more premium “glass box” feel typical of high-end IWC replica watches.
5. The Dial: White vs. Cream
Which one is closer to genuine?

ZF Factory (Correct Tone)
- Color: ZF’s white dial is actually Off-White / Creamy, just like the genuine IW500705. It looks warm and vintage. This makes it a very accurate IWC replica.
- Sub-dials: The concentric circles (CD pattern) are sharp and reflect light well.
APS Factory (Slightly Cold)
- Color: APS’s white dial is a bit Too White / Cold. It lacks that subtle warmth of the genuine. Side by side, it looks stark.
Verdict: ZF Factory wins on dial color accuracy for this IWC replica.
6. Color Guide: Which Version Should You Buy?
Both factories make this IWC replica in multiple colors.
- White Dial / Blue Hands (IW500705): The classic. ZF does this color better (creamier).
- White Dial / Gold Hands (IW500704): The dressiest option. Both factories are good, but ZF’s gold tone is slightly richer.
- Blue Dial (IW500710): The modern choice. APS wins here because the “Cold” tone of the APS dial matches the blue better than the white.
- Black Dial (IW500703): The stealth option. Both are excellent.
7. How to Spot a Fake IWC (Comparison Guide)
Even the best IWC replica has tells. Here is how to spot them.
- The Power Reserve Hand: On the genuine, the hand moves smoothly. On the replica, it can sometimes be a bit “jumpy” or inaccurate.
- The Date Wheel: The genuine date font is very specific (IWC Sans). ZF and APS are close, but under a loupe, the genuine printing is slightly more raised/3D.
- The Movement Finish: The “Geneva Waves” on the genuine movement are deeper and catch the light with a rainbow effect. The replica finishing is flatter.
8. Common Mistakes When Buying an IWC Replica Watch
Even experienced collectors make mistakes when buying an IWC replica. Based on years of hands-on testing and buyer feedback, these are the most common pitfalls:
Mistake #1: Believing Power Reserve Numbers Blindly
Many buyers choose APS solely because of the advertised “160-hour” power reserve. In reality, no current IWC replica delivers a true 7-day reserve. APS performs well at ~80–90 hours, but expectations must be realistic.
Mistake #2: Ignoring Dial Color Differences
For the IW500705 white dial, ZF’s warmer, cream-toned dial is visibly closer to genuine. Choosing APS for this reference purely for specs often leads to regret once compared side by side.
Mistake #3: Underestimating Service Risk
Integrated movements look impressive, but proprietary IWC replica movements can become problematic after several years. Replacement parts availability matters just as much as performance on day one.
Mistake #4: Buying Without Considering Wrist Size
At 42.3mm with a large dial opening, the Portugieser wears bigger than most dress watches. Buyers with wrists under 16.5cm may find it visually oversized, regardless of factory.
“If you find the Portugieser too dressy and want a sportier chronograph, check out our review of the Clean Factory Rolex Daytona 116500LN.”
9. Who Should NOT Buy the APS IWC Replica?
Despite its impressive technology, the APS Factory IWC replica is not for everyone.
You should reconsider APS if:
- You plan to keep the watch for 5–8 years and want easy servicing.
- You prioritize dial color accuracy over mechanical innovation.
- You prefer proven, mass-tested movements with readily available parts.
- You dislike being an early adopter of new IWC replica technology.
APS is best suited for collectors who enjoy cutting-edge replica engineering and are comfortable upgrading or replacing the watch in the future if needed.
If you value peace of mind and longevity, ZF Factory remains the safer long-term choice.
10. Final Thoughts: APS vs ZF — No Hype, Just Reality
The APS vs ZF debate marks an important turning point in the IWC replica market. For the first time, buyers must choose between technical ambition and refined execution.
APS Factory proves that true integrated movements are possible in modern IWC replicas. ZF Factory proves that refinement, color accuracy, and reliability still matter just as much.
For experienced collectors, owning both is not unreasonable.
For first-time buyers, ZF remains the smarter entry point.
There is no marketing winner here — only informed decisions.
