What IW545179 is
IW545179 is an IWC reference number. IWC prints references as IW plus six digits. The first four digits name the family and the last two name the variant. IW545179 sits in the 5451 family.
We could not confirm an official IWC spec sheet for IW545179. Listings that use the number describe a round, hand-wound watch with a small seconds subdial. Confirm case diameter, dial color, and strap with the seller before you pay.
What replica sellers offer under this reference
Replica listings reuse the IWC number as a product code. Two sellers can ship different watches under the same code. Ask for photos of the actual unit, not catalog images.
- Case diameter in millimeters, measured with calipers
- Movement type: hand-wound, automatic, or quartz
- Dial print: font, spacing, subdial position
- Caseback: solid or sapphire, engraving depth
- Strap material and buckle type
Check points before you buy
Case and dial
Measure the case. A 1 mm difference shows on the wrist. Compare the subdial position against a reference photo. On a small seconds layout the subdial sits at 6 o'clock. A misplaced subdial is the easiest flaw to spot.
Movement
Low-price hand-wound replicas often carry a decorated automatic. Ask for a movement photo and a short video of the winding action.
Caseback
Engraving depth and font matter more than the text. Laser etching looks flat under raking light. Stamped or milled marks show shadow.
Price bands
- Under $100: quartz movement, printed dial, mineral glass.
- $150 to $400: hand-wound or automatic clone, sapphire crystal, better dial print.
- Above $500: closer case finishing, correct subdial spacing, sapphire caseback.
Price does not guarantee quality. A $200 unit with a good dial beats a $600 unit with a wrong case shape.
Legal and shipping facts
Counterfeit watches are illegal to sell in the US. US Customs and Border Protection can seize a shipment and destroy it. The buyer loses the money and the watch. Know this before you order.
Care
Hand-wound replicas need service every 3 to 5 years. Do not wind past the stop point. Keep the watch away from magnets and water unless the caseback gasket is intact.
