Quick answer
The IW328070 is an IWC Pilot's Watch Mark XX reference. Replicas of this reference sell from about $150 to $500 from Chinese sellers. The build splits into three tiers: quartz or low-grade automatic at the bottom, Miyota 9015 in the middle, clone or modified Swiss-pattern automatic at the top. The genuine case is 40 mm wide, 10.8 mm thick, with a 20 mm lug width. IWC rates water resistance at 100 m and lists a 120-hour power reserve for calibre 32111. No replica matches that reserve.
IWC IW328070 Imitation: What to Check Before You Buy
What the genuine reference is
IWC builds the Mark XX in stainless steel. Diameter 40 mm, thickness 10.8 mm, lug width 20 mm. Sapphire crystal on the front and the back. Soft-iron inner case for magnetic protection. Water resistance 100 m. Calibre 32111, automatic, 28,800 vibrations per hour, 120-hour power reserve. Strap options include leather, textile, and a steel bracelet with the EasX-CHANGE system.
Dial and strap variants inside the Mark XX family carry different reference numbers. Confirm the exact dial color for IW328070 against the IWC catalog before you buy. Sellers reuse one number across several variants.
Replica tiers and prices
- Low tier, $150 to $220: quartz or a low-grade Chinese automatic, mineral or coated glass, flat printed dial, engraved case back.
- Mid tier, $230 to $320: Miyota 9015 or a Seagull movement, sapphire crystal, 316L steel, correct 40 mm case.
- High tier, $330 to $500: clone or modified Swiss-pattern automatic, sharper dial printing, anti-reflective sapphire, closer case profile and lug shape.
Checks before you pay
- Movement: ask for the calibre name and a photo of the rotor. "Swiss movement" with no name is a claim, not a fact.
- Case size: 40 mm diameter, 20 mm lugs. A 42 mm case is a different watch.
- Dial: check the date window position and the weight of the numeral font.
- Water resistance: most replicas get no pressure test. Treat 100 m claims as unverified.
- Payment: use a method with a dispute process. Bank transfer has none.
Limits
Genuine calibre 32111 runs 120 hours. Miyota 9015 runs about 42 hours. A replica with a 9015 stops sooner and needs more winding. Resale value sits near zero. IWC service centers will not service a replica, and internal parts do not interchange with the genuine watch.
Factory context
The Guangzhou factories that build Rolex replicas also build IWC Pilot replicas. Movement supply, case machining, and dial printing come from shared vendors. IWC models draw less demand than Rolex models, so the top tier for a Mark XX sits below the top tier for a Submariner in finish quality.
US legal note
US customs law bans import of goods that copy a registered trademark. CBP can seize shipments and notify the rights holder. A domestic sale of a counterfeit watch carries the same trademark problem under federal law.
