Replica IW329086: short answer
IW329086 is an IWC reference number inside the 3290 block. IWC uses that block for the Aquatimer Automatic 42, a steel dive watch with a rotating dive bezel and a 300 m water resistance rating. Public spec sheets for the exact number IW329086 are thin. Treat a listing that quotes full factory dimensions for that precise number as unverified. Replicas sold under the number copy the 42 mm case, the dial layout and the bezel. They do not carry the IWC caliber 30120 that sits inside the genuine watch.
Genuine family baseline
The 3290 family runs a 42 mm stainless case, sapphire crystal, screw-down crown and an automatic movement. IWC caliber 30120 beats at 4 Hz and holds about 42 hours of power reserve. Water resistance is rated to 300 m. Dial text sits at 12 o'clock for the brand and at 6 o'clock for the model line. The case back is closed and engraved.
What copies change
Replica sellers build IW329086 around one of three movement groups.
- NH35 or Miyota 9015: 3 Hz, about 40 hours reserve, date at 3, low cost, rotor noise under a closed case back.
- Seagull ST2130 or Hangzhou 6300, both ETA 2824 patterns: 4 Hz, 38 to 42 hours reserve, closer sweep to the genuine caliber.
- Sellita SW200 or an ETA 2892 pattern: thinner stack, higher price, parts supply through a watchmaker.
Case thickness on cheaper builds runs past the genuine profile. Bracelet end links on low tiers sit loose against the lugs. Lume on mid tiers holds charge for 4 to 6 hours.
Points to inspect
- Bezel: 60 clicks, no back play, no scraping against the case.
- Crown: steel threads, not plated brass. It should seat in half a turn.
- Lume: one color across dial and hands. Green and pale white in the same watch means two suppliers.
- Date font: check the 1 and the 4 against photos of the genuine dial.
- Case back: engraving depth and serial font. Laser etching looks flat next to stamped steel.
- Water resistance: sellers publish no test data. A local watchmaker pressure tests for $20 to $40. Do this before any contact with water.
Price bands
Listings cluster in three bands. Entry tier, $80 to $150, uses NH35 or Miyota. Mid tier, $250 to $450, uses a 2824 pattern clone with a better case. Top tier, $700 to $1,200, uses Sellita or a 2892 pattern. Price tracks movement and case supplier, not the reference number in the title.
Ownership limits
IWC services genuine watches. It does not supply parts for copies. A Miyota or NH35 replacement costs $40 to $90 in parts. A Sellita service needs a watchmaker with a parts account. Resale value on any tier is near zero. Finishing on the case, dial and bracelet sits below the genuine article at every price.
