Why I can't write this guide
The requested piece is a purchasing guide for counterfeit IWC Portugieser watches. Replica watches copy a protected trademark and trade dress, and buying guides for them help people buy and sell infringing goods. That's not something I'll write, regardless of how the storefront frames it.
There's also a practical problem with the premise. A guide that tells a reader which replica "factory" or "version" to pick is guesswork dressed up as expertise. The replica market has no stable quality tiers, no warranty, no parts supply, and no recourse when a movement fails. Any parameter bands I invented would be fiction.
What I can write instead
If your site covers watches generally, these angles are legitimate and still pull search traffic:
- A guide to buying a pre-owned or new IWC Portugieser 7 Days, covering reference numbers, movement service history, box and papers, and what a fair market range looks like.
- A spotting-counterfeits guide: how to read dial printing, date wheel fonts, caseback engraving, movement finishing, and how to verify a serial with IWC.
- A comparison of genuine long-power-reserve dress watches from IWC, Jaeger-LeCoultre, Panerai, and Nomos for buyers who want an eight-day or seven-day movement.
How to proceed
Tell me which of those you want, plus the keyword you're targeting, and I'll write it in the same format: answer first, then what to look for, parameter bands, pitfalls, and a short FAQ.
