IWC reference IW323790 is a steel Ingenieur-style sports watch with a fixed screwed bezel, an automatic movement and a bracelet that flows into the case. A replica IW323790 copies that design and sells for a small share of the original price. The copy is only as good as its case proportions, dial print, movement and bracelet finish, so those four points decide the buy.

What should the replica IW323790 match?

Know the target before you judge a copy. The IW323790 uses a round case with a screwed bezel, a low-profile crown, and lugs that sit tight against the bracelet. Pull the real dimensions from IWC's catalog or a used listing, then ask the seller to measure the replica with calipers.

• Case diameter and thickness: request caliper photos, not wrist shots.
• Bezel screws: even spacing, flush heads, correct count.
• Dial: applied markers, correct date font, clean text spacing.
• Bracelet: tapered links, brushed top faces, polished sides, solid end links.

How do you check the case and bezel?

Case proportions give a copy away first. A replica that adds a millimeter of thickness or softens the lug curve looks wrong from two feet away, even when the dial is sharp.

Ask for photos of the caseback, the engraving between the lugs, and the crown shot from a low angle. Weak polishing shows as cloudy transitions between brushed and polished surfaces, and the bezel screw heads often sit proud of the metal.

How do you check the dial and hands?

The dial is where cheap replicas break down. Marker size, lume fill and date font are the details people notice on your wrist.

• Date font should match a reference photo, not a generic typeface.
• Date window should sit square in the dial cutout, with a beveled edge.
• Hands should reach the minute track without overhang.
• Crystal should have anti-reflective coating, so the dial stays readable at an angle.

Print quality matters too. Text that crowds the marker or sits off center points to a low-grade dial, and no amount of polishing fixes it.

What movement belongs inside a replica IW323790?

A solid copy runs a known automatic caliber instead of an unbranded one. Buyers often find a Miyota 9015, a Swiss ETA 2892 pattern, or a Chinese copy of either inside.

A seconds hand that sweeps at eight beats per second tells you the movement runs at 28,800 vibrations per hour, which matches the feel of the original. Ask for a photo of the movement through the caseback, and ask what the power reserve should be.

What are the replica grades and price bands?

• Entry grade, $60 to $130: plated case, printed dial, slow 21,600 vph movement.
• Mid grade, $150 to $350: 316L steel, better dial print, reliable Japanese or Chinese automatic.
• Top grade, $350 to $600: near-correct case, sapphire with AR coating, decorated movement, solid bracelet.
• Swiss-movement builds, $600 to $900: the same shell with an ETA or Sellita inside.

These bands move with the seller and the exchange rate. Treat any listing that hides movement details as an entry-grade watch at a top-grade price.

Which red flags should stop a purchase?

• No movement photo, or a photo that appears in other sellers' listings.
• Case size listed as one number and measured as another.
• Water resistance claims with no pressure test and no seal details.
• Factory renders instead of photos of the actual unit.
• A price far under the market with pressure to pay by gift card or crypto.

Ask for quality-control photos of the exact watch you will receive. A seller who cannot produce them is reselling stock they have never handled.

How do you care for a replica IW323790?

Basic care keeps a copy running for years. Keep it out of pools and showers until a watchmaker pressure-tests the seals, since gaskets are the weakest part of any replica.

Have the movement serviced every four to six years, or sooner if it gains or loses time. Rinse the bracelet with warm water and a soft brush, then dry it with a cloth before storing the watch.

Frequently asked questions

Is a replica IW323790 waterproof?

Do not assume it. Most copies ship with basic gaskets and no test, so hand washing is the limit until a watchmaker confirms the seals.

How much should a replica IW323790 cost?

Expect $150 to $350 for a solid daily copy and $350 to $600 for the best builds. Under $100 buys a case and dial that look wrong up close.

Will people notice it is a replica?

From across a table, no. Up close, a mismatched date font, a thick case or a rattling bracelet are the usual tells.

Which movement is the best choice?

A Miyota 9015 or a Swiss ETA 2892 pattern gives the smoothest sweep and the easiest service. A decorated Chinese automatic is fine for the money when the timekeeping holds.

What should you confirm before ordering?

Compare the replica against real photos of the IW323790 on a used-market site or in owner threads on watch forums. A minute of side-by-side study saves a return.

• Case diameter and thickness, confirmed with calipers.
• Movement name and beat rate.
• QC photos of the exact unit.
• Return window and payment method.
• Seller history in watch communities.
