Answer first

A fake IW544770 is only as good as four details: the dial printing and subdial geometry, the case and lug finishing, the engravings on the caseback, and the movement visible through the display back. Replicas fail on those four points far more often than on overall silhouette, because a case shape is easy to copy and a crisp applied index, a correct date window position, or a properly finished bridge is not. Inspect in that order, under a 10x loupe and in daylight, before you judge a watch by its listing photos.

Prerequisites

  • 10x loupe or a macro lens
  • Digital calipers
  • Daylight lamp plus a raking side light
  • Official reference photos of IW544770 on screen for comparison
  • Soft cloth and finger cots

Step-by-step inspection

1. Confirm the reference details first

  1. Pull the official IW544770 specification sheet and write down case diameter, thickness, lug width, crystal type, and stated water resistance.
  2. Measure the watch you were sent with calipers and compare each number to that list.
  3. Reject the piece if diameter is off by more than 0.3 mm or thickness is off by more than 0.5 mm.

2. Read the dial with a loupe

  1. Check that every printed letter sits at the same height and the same ink weight, with no bridging between letters.
  2. Confirm the subdial spacing matches the reference, since this is the most common failure on replica dials.
  3. Look at the applied numerals and indices from a raking angle, and confirm they are polished metal with a clean bevel, not stamped sheet.
  4. Inspect the date aperture for a centered cut, a squared frame, and a date disc that sits flush with the dial.
  5. Check lume application on each marker for even fill and no overflow onto the dial surface.

3. Judge the case and lugs

  1. Run a fingernail along the case flank and confirm the brushed and polished transitions are sharp, not rounded over from over-polishing.
  2. Check lug tops for a consistent brushed grain that runs in one direction.
  3. Look at the crown for correct proportions, clean knurling, and an engraved logo that is centered and deep.
  4. Confirm the crystal sits at the correct height, with an even edge and no milky halo at the perimeter.

4. Read the caseback engravings

  1. Compare the reference number engraving against the official photo for font, spacing, and depth.
  2. Confirm the serial and hallmarks are laser-crisp, not shallow and dotty from a cheap stamp.
  3. Check the caseback thread for burrs and confirm the gasket is seated evenly.

5. Inspect the movement through the display back

  1. Look for perlage or Cotes de Geneve finishing that is applied rather than printed, and confirm the pattern does not run over screw holes.
  2. Check that blued screws are actually heat-blued steel, not painted heads.
  3. Confirm the rotor engraving is filled and legible, with no smeared edges.
  4. Verify the balance oscillates cleanly at low amplitude and stops crisply when you pull the crown.

6. Test function and feel

  1. Wind the crown slowly and confirm resistance builds smoothly without gritty spots.
  2. Start the chronograph, let it run 60 seconds, and confirm the seconds hand resets exactly to zero.
  3. Set the time forward through midnight and confirm the date flips once, cleanly, without hanging.
  4. Weigh the watch and compare to the reference figure; a large gap usually signals a thin case or a hollow bracelet.

Common red flags

  • Subdial hands that sit too high above the dial surface
  • Printed rather than applied indices on a reference that uses applied markers
  • Caseback engraving that is shallow, uneven, or the wrong typeface
  • Movement decoration that stops at the edge of the bridge
  • Lume that glows unevenly across markers after a 30-second charge

No replica matches a genuine IW544770 part for part. The goal of an inspection is to confirm the watch you received matches the grade you paid for, and that the details people actually notice at arm's length are right.
