Short answer

Replica IW323724 watches are copies of an IWC reference in the 3237 family. The last two digits (24) mark the variant: case metal, dial color, or strap. Replica prices for this reference sit between about $200 and $450. The details that decide quality are case diameter, crystal material, movement, and the date wheel. Ask for caliper photos of the case and a photo of the movement before payment.

What the reference number means

IWC writes references as IW plus six digits. The first four digits name the family. The last two name the variant. Two IW323724 watches can share a case and movement and still differ in dial color or bracelet. Sellers mix variant numbers. Match the photos to the exact variant you order.

Details to verify

  • Case diameter and thickness, measured with calipers. Tape measures add 0.5 mm of error.
  • Crystal. Sapphire with inner anti-reflective coating. Mineral glass shows a blue or purple sheen under a lamp.
  • Movement beat rate. A 21,600 vph movement beats 6 times per second. A 28,800 vph movement beats 8 times per second. Count frames in a slow-motion clip.
  • Date wheel font and alignment inside the window.
  • Bracelet end links. Gaps at the lugs of more than 0.2 mm show on the wrist.
  • Caseback engraving depth. Laser etching is shallow and flat. Stamped or engraved backs cut deeper.

Water resistance

Replica gaskets often fail a pressure test. Treat any depth rating as decoration unless the seller supplies a test report with a date.

What is not known

Full factory specs for every IW323724 material and dial combination are not published in one place. Confirm the exact variant against a reference database or owner photos. Serial level details such as engraving depth change between batches, so one review does not cover the next order.
