The Short Answer

A replica IW938105 is a non-genuine copy of the IWC watch that carries reference number IW938105. Quality ranges from a $60 quartz lookalike to a $400 to $700 clone with a copied automatic movement. Confirm the reference on IWC's own site or a dealer data sheet first, then compare the replica's case diameter, thickness, lug width, dial layout, and movement against those figures. Anything the seller cannot show in photos should be treated as unknown.

What the IW938105 Reference Tells You

IWC reference numbers use the letters IW followed by six digits. The digits mark the case and dial variant, not the movement, the strap, or the production year. Two watches that share one reference can leave the factory with different bracelets or buckles. The 938xxx block sits outside the ranges most collectors see often, so verify the number on IWC's official listing or an authorized dealer's catalog before you trust any spec sheet a replica seller hands you.

Before You Shop

  • The official spec sheet for IW938105: case diameter, thickness, lug width, water resistance rating, and dial layout
  • A digital caliper, if you can inspect the watch in person
  • A jeweler's loupe or a phone with a macro lens
  • The seller's return policy in writing
  • A watchmaker who can pressure test the case if you plan to wear it near water

How to Evaluate a Replica IW938105

  1. Confirm the reference exists. Look up IW938105 on IWC's site or at an authorized dealer. If the number returns nothing, the replica is based on a watch that was never made.
  2. Measure the case. Check diameter across the bezel with the crown excluded, then thickness from caseback to the top of the crystal, then lug width in millimeters. A difference of 1 mm or more changes how the watch sits on the wrist.
  3. Check the dial layout. Look at the placement of the date window, the spacing of any subdials, the thickness of the printed text, and the shape of the applied markers. Misaligned date windows and thin, flat printing are the faults seen most often.
  4. Inspect the crystal. Genuine IWC watches use sapphire with anti-reflective coating. Mineral glass and acrylic scratch faster and show a hazy sheen under a lamp.
  5. Ask about the movement. Request the movement name and a clear photo of the caseback interior. Common options are Miyota and Seiko automatics, Chinese Seagull and Hangzhou movements, and Swiss ETA or Sellita clones. Rough rotor engraving and unfinished bridges mark the lowest tier.
  6. Study the caseback engraving. Check the depth and spacing of the reference number, the serial, and the brand text. Flat, shallow engraving that looks printed rather than cut is a warning sign.
  7. Examine the bracelet or strap. Look for solid end links that fit the case without gaps, screw-in pins instead of friction pins, and a clasp with clean stamping.
  8. Test every function. Wind the crown, set the time, advance the date, and run any chronograph through a full cycle. Reset the chronograph and confirm the hands return to zero.
  9. Question the water resistance rating. A factory claim of 50 m or 100 m is not a test result. Keep the watch out of water until a watchmaker performs a pressure test.

Quality Tiers to Expect

  • Entry: quartz movement or a basic automatic, printed dial, mineral glass, hollow end links, and a stamped clasp.
  • Mid: Miyota 9015 or Seagull automatic, applied markers, sapphire crystal, solid links, and a signed clasp.
  • Top: cloned movement, dimensions that match the reference within a fraction of a millimeter, and finishing close to the genuine article.

Red Flags

  • Photos that never show the caseback or the crown side
  • A Swiss made claim at a price no Swiss movement can cover
  • No return policy, or one that depends on the seller's judgment
  • A refusal to send a short video of the running seconds hand
  • Pre-order listings with open-ended delivery dates

Care and Servicing

Have the watch serviced every three to five years if it runs an automatic movement. Keep it away from speakers, magnetic clasp bags, and phone cases with magnets. Store it on a roll or in a case, and wipe the case and crystal with a microfiber cloth after wear. Replicas seldom carry spare parts, so a watchmaker who cannot source a replacement movement may decline the job.

Legal Note

In the United States, importing or selling goods that carry a counterfeit trademark is illegal, and shipments can be seized by Customs and Border Protection. Buying for personal use is not commonly prosecuted, but the watch can be confiscated. A replica marked with IWC branding is a counterfeit. A watch that copies the general look but carries its own brand name is an homage, and those are legal to buy and sell.
