Quick answer
A fake IW93806 watch and an original separate on five things you can check in under fifteen minutes without opening the case: caseback engraving depth, dial printing crispness, crown and pusher feel, movement beat rate, and total weight. Replicas copy the look at arm's length. They fail under a loupe, on a scale, and on a timing machine.
What IW93806 refers to
Listing titles use IW93806 as a case reference. Genuine modern IWC references carry the letters IW followed by six digits, for example IW371605. A shorter number usually means the seller is quoting a caseback stamp rather than a catalog reference. That detail alone does not prove a watch is fake, but it tells you the listing was built from photos, not from a spec sheet.
Prerequisites
- A 10x jeweler's loupe
- A digital kitchen scale that reads in grams
- A bright, angled desk lamp
- A caliper or a steel ruler
- Access to a watchmaker with a timing machine
Step-by-step comparison
- Turn the watch over and read the caseback text through the loupe. Genuine IWC laser engraving has sharp shoulders and a consistent depth. Replica engraving looks sandy at the edges, and the reference number often sits slightly off center.
- Check the reference number against the official model page. Type the full number into the brand's own site and confirm the case size, dial color, and movement match the watch in front of you.
- Inspect dial printing at 10x. Look at the brand name, the word automatic, and the small text at six o'clock. Genuine printing has clean terminals on every letter. Replicas show ink bridging between strokes and uneven baselines.
- Study the applied indices. On an original, each marker sits flush and level, with the lume fill flat to the top edge. On a fake, markers tilt by a fraction of a degree and the fill domes above the frame.
- Look at the crystal from a steep angle. An original sapphire with anti-reflective coating shows a faint blue or purple tint. A fake often shows no coating at all, or a heavy mirror tint that washes out the dial.
- Wind the crown and press the pushers. The original action is smooth with a defined click at each position. A fake feels gritty, and the pushers travel with a soft, mushy stop.
- Weigh the watch on the scale. Steel IWCs of this size land in a tight range. A fake with a plated brass case reads several grams light, and the difference is obvious once you hold both.
- Check the movement on a timing machine. Genuine modern IWC calibers run at 28,800 vibrations per hour, which is 4 Hz. Many replicas run at 21,600, which is 3 Hz, and the readout shows it in one second.
- Examine the clasp and bracelet engraving. Original clasps carry deep, even lettering and a crisp logo. Replica clasps use shallow stamping and rounded edges on the logo.
- Confirm the paperwork chain. Ask for the warranty card serial, the original invoice, and a service record. A genuine watch has a serial that ties to a dealer. A fake has a serial that repeats across dozens of listings.
What replicas usually get right
Case diameter, dial layout, and the general silhouette are close on mid-tier and high-tier replicas. From two feet away, most people cannot tell. Strap color and buckle shape are also easy to copy, so do not use either as your test.
What replicas usually get wrong
Movement finishing is the biggest gap. Look through an exhibition back at the rotor, the bridges, and the perlage on the main plate. Genuine finishing shows even circular graining and polished bevels. Replicas show machining marks and painted-on stripes. Water resistance is the second gap. A fake rated at 50 meters often leaks at the first swim.
Fake IW93806 Watch Price: What Replica IWC Buyers Actually Pay
Red flags when buying
- A price far below the market range for that reference
- Photos that avoid the caseback, the crown, and the clasp
- A seller who refuses a timing machine reading
- A serial number that appears on other listings in a search
- Pressure to pay outside a protected method
Bottom line
If you want the look and accept the trade-offs, a replica fills that role. If you want resale value, service support, and water resistance, buy the original or a different watch you can afford. Never pay original money for a fake. Run the ten checks first, and walk away from any seller who blocks them.
