The IW329082 is an IWC reference in the 3290 case block, the Aquatimer Automatic 42 line. A replica of it copies the case shape, dial, rotating bezel, and strap. Four parts decide quality: the movement, the crystal, the bezel action, and the water resistance. The rest is cosmetic and can be judged from photos.

Confirm the exact catalog entry with IWC before you compare specs. In IWC numbering, the last digits mark a dial, strap, or market variant, not a new case. Two watches that share a case block can still differ in bezel text, lug width, and crystal shape.

Specs to Compare Side by Side

  • Case diameter and thickness in millimeters
  • Lug width and lug-to-lug length
  • Crystal material and anti-reflective coating position
  • Bezel type, rotation direction, and click count
  • Crown diameter, thread pitch, and guard shape
  • Dial print, font weight, and index height
  • Lume color and brightness
  • Strap or bracelet material, end link fit, and clasp stamping

Movements Used in Replicas

Sellers group movements into three tiers. Quartz versions run on a battery cell and have a stepping seconds hand. Low tier automatics use a Miyota 8215 or a Seagull copy, both at 21,600 vibrations per hour. High tier versions use a decorated clone at 28,800 vibrations per hour. Ask for the caliber name and the beat rate in writing. A 28,800 vph movement sweeps closer to the original. A 21,600 vph movement is common and is not a defect by itself.

Where Replicas Diverge

  • Bezel click count and play between clicks
  • Lume brightness and how long it holds
  • Dial font thickness and letter spacing
  • Date wheel font and window position
  • Crown logo depth
  • Caseback engraving depth and text size
  • Bracelet end link fit at the lugs
  • Crystal clarity and reflection color

Water Resistance

ISO 22810 sets the test method for water resistant watches and the rules for marking them. Factories that build replicas do not publish ISO test reports. Assume no water resistance unless a watchmaker pressure tests the case and gaskets. Do not swim or shower with one before that test.

Price Bands in the US

  • About $80 to $150: quartz or low tier automatic, mineral glass, stamped clasp
  • About $200 to $400: mid tier automatic, sapphire glass, solid end links
  • About $450 to $900: clone movement at 28,800 vph, sapphire with AR coating, closer case finishing

Prices move with the exchange rate and the shipping method. A seller who quotes far below these bands may be selling a lower tier than the listing claims.

Checks Before You Pay

  1. Get the movement caliber and beat rate in writing.
  2. Ask for a photo of the caseback, crown, and clasp.
  3. Ask for the case diameter in millimeters, not the model name.
  4. Read the return policy and the return shipping cost.
  5. Ask how the seller ships and who pays customs fees.
  6. Ask if the watch was pressure tested and at what depth rating.

One limit: this page cannot verify the factory spec of the IW329082 itself. Get that from IWC's own catalog entry, then compare those numbers to the listing.
