The movement inside This reference is built with either calibre. The choice changes the price, the rate and the reserve — nothing else about the watch.
| Base | Seiko NH35 or Miyota 8215, automatic | Swiss clone of the maison's own calibre |
|---|---|---|
| Rate | ±15 to 25 seconds a day | ±5 to 10 seconds a day |
| Reserve | About 40 hours | 55 to 70 hours |
| Balance | 21,600 A/h · six beats a second | 28,800 A/h · eight beats a second |
| Servicing | Any watchmaker can service it; parts are everywhere | Serviced by a specialist; finished as the original is |
| Suited to | Wearing daily, keeping simply, spending less | Matching the reference exactly, and glass casebacks |
The Swiss movement is $50 more. That figure buys the rate, the reserve and a movement that reads correctly through a glass back — not a different watch.
Which we would take. If it is to be worn every day and serviced down the road from you, the Japanese is the honest answer. If it has to survive a loupe against the reference — or the caseback is glass and the movement is meant to be seen — take the Swiss.
The exact base calibre for this reference is confirmed in writing, with the QC film, before anything is dispatched. The two movements, explained

Description
Highly Recommended】 The IWC Portugieser Collection Perpetual Calendar watch, featuring hour and minute hands, date, day of the week, month, 3-day power reserve, and sapphire crystal, is a stunning automatic watch. ZF's 2019 new product—the IWC Portugieser Collection Perpetual Calendar watch—combines hour and minute hands, date, day of the week, month, and power reserve display. As the saying goes, excellence comes late, and great things take time. We invite all watch enthusiasts to appreciate and support this timepiece.
1⃣️【Case】The watch measures 44mm x 15mm with a moderate thickness. The rounded bezel is smooth and natural, and the polishing is glossy and lustrous, maintaining ZF's consistently high standards. The dome-shaped double-sided anti-reflective sapphire crystal is ingeniously cut and polished, extremely difficult, and has a very high scrap rate. ZF spared no expense in replicating the appearance of the genuine product, bringing everyone the most unparalleled experience closest to the real thing.
2⃣️【movement】Disassemble the original IWC52850 movement (326 parts), and through a lot of experimentation and data analysis, achieve an 80% match between the structure and the IWC52850 movement, with 100% synchronization in debugging methods and feel.
3⃣️【Strap Buckle】Italian small calf leather with an original IWC folding buckle!
ZF Factory masterpiece of craftsmanship welcome to view!
