How to Spot a Fake Replica IWC Watch?
You can use a few approaches to identify a replica or fake IWC, I list some methods below for your references. If you want to buy a genuine IWC, you must ensure that the product you are getting is authenticate and not an elaborated copy.
Glue on Crown: Cheap replica IWC watches might have the logo actually glued to the end of the crown. These watches have so many other flaws that this won't be your first indication of problems. Make sure the crown shows no sign of glue or uneven edges. Also, the watch should wind smooth and free, without the feel of the movement moving in the case.
Dirty Dial: There should be no dust on the surface of the dial, and absolutely no fingerprints. Contaminants such as hairs have been known to be found under counterfeit crystals on replica IWC watches. There's no quality control in the replica factories; each replica IWC watch can exhibit a variety of subtle diferences, including such things as contaminants and print quality.
Grammar and Spell: Many of these replica IWC watches are made by people whose first language is not English. Because of this, several spelling errors have slipped into the final products and make determining if a watch is counterfeit very easy. Read carefully the dial and the case back. Check the spelling; don't assume that it's correct. We've seen spelling errors like "Eigtheem Jewels","NIMITED EDITION", and "Made in Swiss", which make it obvious that the watch is not genuine.
Luminosity: Most IWC watches use a substance called LumiNova to provide the glow to the dial and hands that allows you to read the time in darkness. Replica IWC watches normally have a poor quality luminous material applied compared to a genuine watch. The replica won't glow as brightly or as long when charged and viewed in a low light situation. It's also common that replica IWC watches will have missing luminous materials and not glow at all. Use a flashlight to "charge" a watch and observe the brightness of the dial and hands in the dark.
