Quick answer
No IWC catalog page for IW329064 was found at the time of writing. IWC publishes Pilot's Watch models in blocks such as IW3270 (Mark XVIII) and IW3297 (Pilot's Watch Automatic 41). Treat IW329064 as a label the seller wrote, not a factory code. Ask for the case back photo, the movement name, and the measured diameter before payment.
What this reference class points to
Listings that use this number describe a 41 mm steel Pilot's Watch. Genuine numbers for that class: 41 mm case, steel, black dial, white printed numerals, 28,800 vph, 120-hour power reserve on the current generation, sapphire crystal with antireflective coating on both faces, soft-iron inner case, 100 m water resistance, about 11 mm thick. US retail sits near $5,900 to $6,900 depending on strap.
Replica builds you will see
- Asia 2813 or Miyota 8215: 21,600 vph, 38 to 42 hours of reserve, date at 3.
- Miyota 9015 or Seagull ST21: 28,800 vph, about 42 hours, smoother sweep.
- No budget clone of calibre 32111 holds a true 120-hour reserve. A $200 listing that claims 5 days is wrong.
Checks that separate grades
- Power reserve. Wind 40 turns. Set the watch down. Read it again at 48 hours.
- Thickness. Measure with calipers. A genuine 41 mm Pilot's Watch is under 12 mm with the crystal.
- Crystal. Genuine has a blue-tinted reflection from both sides. Cheap builds reflect from one side.
- Dial print. "IWC" and "Schaffhausen" sit level. Date font height matches the numerals.
- Lume. Charge under a lamp. Genuine Super-LumiNova stays readable for hours. Most replicas fade in 20 to 30 minutes.
- Crown. Threads engage without grit on the genuine.
- Case back. Genuine engraving is deep and crisp. Laser etching looks shallow and grey.
- Stamps. Genuine serial and reference marks sit between the lugs.
Price bands
$80 to $150: quartz or 21,600 vph, mineral glass, no soft-iron case. $180 to $400: 28,800 vph, sapphire, clean dial print. $450 and up: best finish, closer bridges, still no 120-hour movement. A replica listed above $700 carries the same legal risk as a cheap one.
Legal note
In the United States, 18 U.S.C. § 2320 sets criminal penalties for trafficking in counterfeit goods. U.S. Customs and Border Protection can seize counterfeit watch shipments at the border. Resale carries higher exposure than a single personal purchase.
Before you pay
Ask for four items: case back photos, a timing machine reading, a video of the second hand sweep, and the movement name. A seller who will not name the movement is a seller you cannot price.
