G Shock by Casio makes trendy timepieces that not only look cool, but are also resistant to wear and tear. Because of the resilience and hipster aesthetic, G Shocks are well known with the younger crowd. While G Shock watches aren't expensive, they're still hot enough that some counterfeiters will try to capitalize on their popularity by peddling fakes. If you want to buy a G Shock watch, know what to look out for so you don't buy a fake.
Every G Shock watch will have the word "Casio" on it. Usually, you'll be able to find the name on the face of the watch. If the watch doesn't say Casio on it somewhere or if it has any other brand name, it's a fake.
Check the back of the watch for a serial number. Every G Shock watch will come with one. If you find a serial number but you're still not sure if your watch is real, jot down the serial number and call Casio customer service. A representative should be able to verify if your serial number matches an actual G Shock watch.
Pay attention to the small details. The button that you use to set time will be on the top left of the watch. Every G Shock watch has a window that tells you the day of the week. The window is located around the top of the watch face, directly in the center, under the 12 o'clock dial.
Learn the specifics of the style that you're looking to buy. The G Shock website allows you to zoom in on photos of all of its watches and gives a list of the specific details of each style.
If you want to purchase through an online auction website, be careful. Auction sites are chock full of counterfeiters trying to trick you into buying a fake watch. The seller should provide lots of photos, and check that the seller has a good buyer feedback rating.
