If you are shopping for a fake IW323797, the first piece of advice is the one most buyers ignore: put the money toward a documented pre-owned genuine IWC or a well-specified homage instead. A counterfeit of this reference carries no warranty, no service path, no parts availability, and no resale value, and the person selling it takes on real legal exposure. If you still want to inspect one in person, or you are trying to work out whether a watch being offered to you is genuine, the checks below are the ones a counterfeit almost never survives. Confirm every specification against IWC's own published data for the reference before you compare anything, since model family and caliber details vary by production year.
Why this reference gets copied
The IW323797 sits in a sport-watch bracket where buyers expect a certain look: a steel case, a rotating or fixed bezel, high water resistance, and a legible dial with strong lume. That combination is easy to photograph and easy to imitate at a glance. What is hard to imitate is the case finishing, the fit of the bracelet end links, the crispness of the printing, and the movement underneath. Counterfeiters spend their budget on the photograph and skip everything the photograph hides.
What to check before money changes hands
Case and crystal
Run a fingernail along the edge between the brushed and polished surfaces. Genuine cases transition on a sharp, defined line; copies tend to blur it or round it off. Check the crystal for a proper anti-reflective coating that reduces glare without turning the dial milky, and look for distortion at steep angles. Look at the bezel action: it should index with a firm, even click around the full rotation, not wobble or skip.
Dial, hands, and date
Printing under a loupe is the fastest tell. Genuine indices and text are sharp, level, and evenly spaced, with no bleed at the edges. The date window should be centered and the numeral should sit square in it. Hand finishing matters too: look for polished bevels on the hands and a sweep second hand that moves in small steps rather than a visible stutter.
Movement
If the watch has a display back, look for a clean plate finish, correctly engraved branding, and no machining marks. If it is a closed case back, ask for a timed rate reading from a watchmaker. A healthy automatic in this class typically holds roughly -10 to +15 seconds per day with a power reserve in the high 30s to low 40s of hours, and the beat should be steady in all positions. A copy often runs fast, runs ragged when tilted, or stops before the stated reserve.
Serial, papers, and history
Have the case number and movement number verified through IWC service before you pay. Numbers that do not match between case back and paperwork, a serial that returns no record, or a seller who refuses an authentication appointment are all conclusions, not clues. Original boxes and booklets are easy to source separately, so treat paperwork as supporting evidence, never as proof.
Specs worth comparing
Pull the official figures for the exact reference and check them one by one: case diameter and thickness, lug width, water resistance rating, crystal material, and stated power reserve. A listing that quotes a diameter half a millimeter off, claims a water resistance the reference never carried, or describes a movement that was not used in that production run is describing a different watch. Weight is also useful. A genuine steel sport watch on a bracelet has a density that copies routinely miss by 20 grams or more.
Traps in listings
- Photos that are low resolution, heavily filtered, or reused from another seller.
- Pressure to pay by wire or a payment method with no buyer protection.
- A price far below the going rate for the reference, framed as a quick sale.
- Claims of a full service with no invoice, no watchmaker name, and no date.
- Refusal to meet at a jeweler, an authorized dealer, or a watchmaker for inspection.
FAQ
Can a jeweler tell a fake IW323797 on sight?
Sometimes, but not reliably. The dependable route is a watchmaker opening the case and comparing the movement and numbers against IWC records.
Does a counterfeit hold any value?
No meaningful resale market exists for counterfeits, and many dealers will not touch them even for parts.
What if the seller offers a guarantee?
A guarantee from an anonymous seller is unenforceable. Only a written return window with a protected payment method gives you any real recourse.
Is a homage the same thing as a fake?
No. A homage borrows a general style but carries its own brand name and does not copy trademarked logos or reference numbers.
