Quick answer
A replica IW544745 is a counterfeit copy of an IWC watch. Sellers use the IW544745 reference number to identify it. Quality depends on the factory. Top-tier copies sell for $300 to $500. Budget copies sell for $80 to $150 and show gaps in the case, dial and movement.
This guide does not list the case diameter or caliber of the genuine IW544745. IWC's own catalog is the source for those numbers. Compare every seller photo against that catalog entry.
The reference number, decoded
IWC uses a six-digit reference after the IW prefix. The first four digits name the model. The last two digits name the case and dial variant. So IW5447 is the model, and 45 is the variant.
Replica sellers engrave the full number on the caseback. A missing number, a wrong number or a blurry engraving points to a low-grade copy.
Five checks before payment
- Case diameter and thickness. Ask for caliper photos. Compare with the IWC spec.
- Dial printing. Numerals and text should have sharp edges and even spacing.
- Applied indices. Painted indices sit flat on the dial. Applied indices cast a shadow.
- Crystal. Sapphire resists a steel pick. Mineral glass does not.
- Movement. Request a photo of the caliber and the rotor engraving.
Case and finishing
Brush and polish lines should meet at a clean edge. Lugs should be symmetrical. The crown should turn without grit and should screw down if the original screws down. Caseback engraving depth varies. Laser engraving looks shallow and light. Stamped engraving has depth.
Weight is a rough test. A 42 mm steel watch on a steel bracelet weighs 120 g to 160 g. A copy with a thin case and a hollow bracelet weighs less.
Movements in copies
Chronograph copies use a 7750-based automatic. That movement is 7.9 mm thick, so the case runs thicker than the original. Three-hand copies use a Miyota 9015, a Seagull ST21 or a clone of the original caliber. Hand-wound copies use a generic manual movement.
A closed caseback hides all of this. Sellers know that. Ask for an open-back photo or a video with the caseback removed.
