An imitation IW329035 is a replica of the IWC Aquatimer Automatic 42 mm dive watch. Good replicas copy the case shape, the dial layout and the rubber strap. They do not match the original 300 m water resistance, and the movement inside is a third-party automatic, not IWC caliber 30120.
What the IW329035 is
IW329035 sits in the IWC Aquatimer Automatic 42 family. That family uses a 42 mm steel case, an internal rotating dive bezel under the crystal, sapphire glass and a rubber strap. The movement is IWC caliber 30120 with 28,800 vibrations per hour and a 42-hour power reserve. IWC rates the watch to 300 m.
Dial and strap variants change across the reference range. Check the reference card and the caseback engraving before you compare a replica to photos, because a replica built for one dial color will not match another.

Replica versions on the market
Factories sell the IW329035 replica in three broad tiers. Builds differ in case finishing, dial printing and movement.
- Entry builds: Chinese automatic, printed dial, mineral glass, stamped caseback.
- Mid builds: Miyota 9015, sapphire glass, applied markers, better bezel alignment.
- Top builds: decorated clone movement, sharper case edges, closer date font, deeper engraving.
Ask which movement is inside. A Miyota 9015 runs at 28,800 vph and takes parts from standard suppliers. Unbranded clones often have no spare parts.
Specs to verify before you pay
- Case diameter 42 mm and thickness close to the original. Ask for caliper photos.
- Bezel action. The inner bezel should turn with firm clicks and line up at 12.
- Date window. Font, position and window cut are the three common tells on this model.
- Crown. Threads should engage without grit, and the crown should sit flush when screwed down.
- Lume. Charge the dial for 30 seconds and compare brightness at 5 and 30 minutes.
- Caseback. Engraving should be crisp, with the reference number readable.
Price ranges
Listings fall near $100 to $150 for entry builds, $200 to $350 for mid builds and $400 and up for top builds. Prices move with the seller and the strap. A low price with a Swiss label is a warning sign. Swiss-made replica claims are common and hard to verify.
Water resistance and service
Do not trust a replica in water out of the box. Gaskets, caseback threads and crystal sealing differ from the original. A watchmaker can pressure test the case and replace gaskets. Even after a test, keep the watch out of diving and shower use. Movement service is possible for Miyota and ETA clones. Decorated clones may need a full replacement.
Common faults
- Bezel insert off by half a click.
- Sharp case edge at the lugs.
- Lume that fades within 20 minutes.
- Rubber strap with a chemical smell and a stiff keeper.
- Rotor noise on the wrist from a dry movement.
Buying checklist
- Request a timestamped photo with the crown unscrewed.
- Ask for a video of the seconds hand and the date change.
- Get the movement name in writing.
- Check the seller return window.
- Budget for a service or pressure test in the first month.
Short answers
Is the replica 300 m water resistant?
No. Treat it as splash resistant at best until a watchmaker tests the case.
Does it use IWC caliber 30120?
No. Replicas use Miyota, Seagull or ETA clone movements.
