IW323793: quick answer

IW323793 is an IWC reference number. The IW3237 group is the Ingenieur Automatic. The final digits mark the dial color, case metal, and bracelet combination. Public spec sheets for every suffix variant are not complete, so treat any seller spec as unverified until you see a caseback photo of the exact piece.

What the genuine watch is

The Ingenieur Automatic of this generation uses a 40 mm steel case. Five screws sit on the bezel. The movement is the calibre 30110, built on an ETA 2892 base. Beat rate is 28,800 vph. Power reserve is about 42 hours. Water resistance is rated to 120 m. If the -93 variant differs in case size or metal, the seller photos will show it.

Replica tiers and prices

Three tiers show up in the market.

  • Entry: $80 to $150. Quartz or low-grade automatic. Plated case and bracelet.
  • Mid: $180 to $350. Automatic movement. 316L steel.
  • Top: $380 to $700. Clone calibre, 904L or 316L steel, engraved caseback, sapphire with AR coat.

Prices move with the metal and the movement.

Movement check

Ask for a photo of the movement and a timing machine reading. A 28,800 vph movement reads 8 beats per second. Copies of the 2892 fit the same case. A quartz movement ticks once per second. Reject any listing that hides the movement.

Case, dial, and bracelet checks

Measure the case. 40 mm across, not counting the crown. Bezel screw slots should line up. Dial print should sit at the same distance from the center on every marker. Date font matters. Bracelet end links should sit flush with the lugs. Clasp engraving should be sharp, not laser-etched.

QC checklist before shipping

  1. Caseback photo with the reference number.
  2. Timing machine photo, rate between -10 and +15 seconds per day.
  3. Crown action video, three positions.
  4. Bezel screw photo, all five present.
  5. Date flip photo, single jump at midnight.
  6. Lume photo, dial and hands glow.
  7. Weight in grams.

Red flags

Stock photos instead of QC pictures. Payment by irreversible methods with no refund path. No movement photo. Price far below the tier. "Swiss made" claims on a $120 watch.
