Short answer

IW329065 does not appear in IWC's published model list. The number falls inside the IW3290 block, which covers the Pilot's Watch Automatic 36. Sellers use "IW329065" as a listing label. Treat the string as a search term, not as a factory reference.

What the IW3290 block covers

IWC reference numbers begin with IW followed by six digits. The first four digits name the family. The last two name the variant: case metal, dial color, strap or bracelet. IW3290 is the Pilot's Watch Automatic 36. Variants in that block share a 36 mm case, a soft-iron antimagnetic inner case, and the caliber 35111 automatic movement. A listing labeled IW329065 should match those specs. If it does not, the listing is wrong.

Checks on a listing

  1. Measure the case. The Automatic 36 is 36 mm across, crown excluded. Replica cases often run 38 mm to 40 mm because they use a stock case and a generic movement.
  2. Check the thickness. A real Automatic 36 sits close to 10.5 mm. Anything near 12 mm or more holds a different movement.
  3. Read the movement. Caliber 35111 runs at 28,800 vibrations per hour with 25 jewels and about 42 hours of power reserve. Common substitutes in fakes are the Miyota 9015 and the Seagull ST2130. Rotor engraving and finish differ from the original.
  4. Inspect the dial. Print is sharp at 10x magnification. The IWC mark, the Schaffhausen line, and the minute track should be clean. Fuzzy edges, thick paint, and a misaligned date window are common faults.
  5. Inspect the caseback. Reference and serial numbers are engraved with a cutter, not laser printed. Fake engraving is shallow, and the digits are uneven in height and spacing.
  6. Weigh the watch. A steel case and a sapphire crystal carry mass. Fakes feel light for their size.

Prices

The Pilot's Watch Automatic 36 sold new in the $4,000 to $5,000 range on leather. Used prices sit below that. Ads at $150 to $700 with IW329065 in the title are replicas. No recent steel IWC automatic sells in that band.

Papers and serial numbers

Ask for the warranty card, the booklet, and the original invoice. IWC does not publish an online serial database. A boutique or an authorized service center can check a serial against the model when the watch is presented for service. A seller who refuses an inspection is a seller to skip.

Limits

Photos cannot confirm a movement. A real case and dial with a fake movement is a common build. Only a watchmaker with the caseback open can confirm the caliber. Add the cost of an inspection to the price before you decide.
