Short answer
A fake IW323704 is a counterfeit copy of the IWC Ingenieur Automatic reference IW323704. No single photo proves it. The reliable tells are the case finishing, dial printing, bracelet fit, caseback engravings, and movement. If you cannot inspect those in person, or have a watchmaker open the watch, do not treat a low price as a bargain.
What the real IW323704 is
The IW323704 belongs to IWC's Ingenieur Automatic family, the steel three-hand line with a date and an integrated-style bracelet. The Ingenieur is an antimagnetic design, so the case, dial, and bracelet should feel like one engineered object, not a watch head dropped onto a generic strap. Exact specs vary by production run, so match any claim to the reference and the papers, not to a seller's description.
Case and bezel
I look at the edges first. A genuine Ingenieur case has crisp transitions between brushed and polished surfaces. The bezel slope is even. The lugs are symmetrical. Fakes often show soft corners, a wavy bezel line, or polishing that spills onto brushed flats. Run a fingernail along the caseback edge. It should catch a clean step, not a rounded lip.
Dial and date
Dial print is where many copies give themselves away. The IWC logo and the Ingenieur text should be sharp at arm's length and under a loupe. Applied indices should sit flat and line up with the minute track. The date should sit square in its window, with even gaps. On a fake, the print can look fuzzy, the lume can be uneven, and the date wheel can sit low or off-center.
Bracelet and clasp
The bracelet is half the watch on an Ingenieur. Genuine end links meet the case with tight, even gaps. The links articulate without rattling. The clasp closes with a solid click, and the engraving is crisp. A fake often has loose end links, sharp edges that were never deburred, or a clasp that flexes. Check the screws too. Cheap screws burr the first time a watchmaker touches them.
Caseback, serial, and movement
Engravings should be deep enough to read at an angle, with consistent fonts. The reference and serial should not look laser-printed or shallow. If the watch has an exhibition back, look at the rotor engraving, jewel settings, and finish. A watchmaker can identify the movement family and spot a clone. Do not rely on a seller's movement photo. Ask for a timed video with the crown pulled and the date changing.
Paperwork and price
Box and papers help a story. They do not prove a watch is real. Fake manuals and warranty cards exist. Compare the asking price with several IW323704 listings and expect a real one to sit in a narrow band. A price that is far below the market needs a reason. 'It came from an estate' is not a reason you can verify.
Before you pay
- Ask for macro photos of the dial, caseback, clasp, and bracelet end links.
- Get the serial and reference photographed together.
- Have a watchmaker open the case and confirm the movement.
- Meet at a jeweler or use an escrow service that inspects watches.
- Walk away if the seller avoids any of the above.
A fake IW323704 can look close in a wrist shot. In hand, the details and the movement decide it. Buy the watch, not the story.
