An IWC IW328070 imitation is a third-party copy of an IWC reference, and the useful answer is that quality runs from disposable to close enough that only a trained eye catches it. A copy is worth considering only when the movement, case finishing, and dial details hold up in person rather than in a seller's photos.
Start with the reference, not the listing
Any honest comparison begins with IWC's own specification for the IW328070: case diameter, thickness, lug width, crystal type, movement, and water resistance. Sellers describe imitations in loose terms, so write the real numbers down and measure what arrives. A case that is a millimeter thicker than the original wears differently on the wrist, and a lug width that is off by half a millimeter will not accept a genuine strap.
Movement: the clearest dividing line
The movement separates an IW328070 replica into clear tiers. Budget examples use basic Asian automatic calibers that keep time but feel gritty when wound. Mid tiers step up to better-finished Asian movements, often from Miyota, Seagull, or Hangzhou. The strongest copies use a genuine ETA or Sellita caliber, or a well-made clone of one.
- Feel the winding action and the snap of each crown position.
- Watch the seconds hand sweep. A stuttering sweep points to a cheap caliber.
- Inspect rotor engraving and movement finishing through the caseback.
- Confirm the power reserve matches what the seller promised.
- Check how the date flips, and whether it flips cleanly at midnight.
Case, crystal, and finishing
Case work is where mid-tier and top-tier copies pull apart. Look at the transition between brushed and polished surfaces: it should be sharp and consistent along the whole flank. The lugs should have the same curve as the original, since that shape drives how the watch sits on the wrist. The crystal should be sapphire with an anti-reflective coating on the inside, and it should not show a purple or blue haze at an angle.
IWC IW328070 Copy: Facts, Legal Risks, and Safer Options
Crown size, thread pitch, and alignment matter more than most buyers expect. On the original the crown sits flush against the case when screwed down, with the logo oriented correctly.
Dial, hands, and printing
Print quality is the fastest tell. Compare the weight and spacing of the brand text, the sharpness of the numerals, and the finish on the hands. Applied markers should sit level, with clean edges and lume that fills the frame without spilling over. A date window should be cut squarely and match the dial color of the original.
Bracelet and strap
End links should meet the case with no gaps. Check the clasp engraving, the spring bars or screw pins, and how the links articulate. A stiff, rattling bracelet undermines an otherwise convincing IWC imitation watch.
Questions to ask a seller
- Which exact movement is inside, and is it Swiss or Asian?
- What are the measured case diameter and thickness?
- Is the crystal sapphire, and is the coating internal?
- What is the water resistance rating, and was it tested?
- Can you send photos of the actual piece, not stock images?
Practical and legal risks
Counterfeit watches can be seized by customs, are illegal to import in many countries, and carry no manufacturer warranty or service support. Resale value is close to zero, and a local watchmaker may refuse to service a movement with copied markings. Treat any purchase as a risk decision, not an investment.
The short version
Judge a copy by what you can verify: the caliber, the case measurements, the finishing transitions, and the dial printing. Photos hide flaws. Measurements and the movement inside do not.
