Casio is one of the most copied watch brands in the world, and G-Shock is the favourite target. The reasons are simple: the watches are famous, the designs are easy to imitate on the outside, and plenty of people will pay a bit to look like they own the real thing. That is not an AliExpress problem alone, but AliExpress has plenty of listings where "Casio" is a keyword rather than a promise.
No checklist can prove a watch is genuine from a screenshot. What a checklist can do is stop you from falling for the obvious traps, and tell you when to walk away. We have not tested the watches we link to, and we cannot verify any individual listing, so treat this as risk reduction, not a guarantee.

Start with the store, not the watch
The store tells you more than the product photo does. Look for clear Casio branding or an official-store badge, a long history, and a high rating built on a large number of orders. A store that opened a few months ago and sells every brand at half price deserves suspicion. So does a store whose catalogue jumps from Casio to phone cases to garden furniture.
Open the store's other listings. A genuine-minded seller usually has consistent product photos, clear model names and sensible price gaps between models. A seller selling fifty "G-Shocks" at nearly the same low price is telling you something.
Sanity-check the price
Compare the price with what authorised retailers charge in Singapore for the same model code. Sales and clearance exist, and AliExpress can genuinely be cheaper. But a popular G-Shock or Edifice at a fraction of the usual price is the most common counterfeit warning sign there is. If the deal feels unreal, assume there is a reason.
Low prices matter less for the cheapest classics, which are inexpensive even at retail. The warning gets louder as the model gets more desirable: metal G-Shocks, limited colours and anything with a collector following.
Match the model code
A genuine listing names a model, such as GA-2100, DW-5600 or F-91W. Look it up on Casio's own pages and compare the colours, the button layout, the text on the dial and the features. Be careful with titles that include "style", "inspired" or "like", or that avoid the model name altogether and just say "Casio sport watch".
Watch out for listings that bundle many models under one product page with a dropdown. The photos may show one watch while the cheapest option is something else entirely.
Read the photos, not the headline
Open reviews with photos and look at the caseback. Many genuine Casios show the model number and a module number there, along with the water resistance marking. Blurry casebacks, missing text or a model number that does not match the listing are red flags. Also check whether the seller's photos look like stock images copied from Casio's site or from other stores.
Compare features with the manual. A watch advertised with a function the real model does not have, or lacking one it should have, is not your watch.
When it arrives
Film the unboxing from the moment the parcel is sealed. Check the logo printing, the alignment of the dial text, the feel of the buttons, the backlight, the alarm and the stopwatch. Compare the weight and strap quality with what you expect from the model. Do not rely on the box alone, because packaging can be copied too.
If something is off, open a dispute within the Buyer Protection window and attach your video and photos. Do not leave a glowing review first and hope the problem goes away.
When to buy elsewhere
If you want certainty and local after-sales support, an authorised retailer is the safer choice, even at a higher price. AliExpress works best for buyers who enjoy doing the homework and accept some risk. See our buying guide for warranty, GST and delivery, or browse what is hot in Singapore with these checks in mind.
Quick answers
Can I be sure a listing is genuine?
No checklist guarantees it. You can reduce the risk by checking the store, price, model code and buyer photos, and by buying from authorised retailers when certainty matters.
Is a very low price always a fake?
Not always, but for popular G-Shock and Edifice models it is a common warning sign. Treat it as a reason to dig deeper.
What if I received a fake?
Open a dispute through AliExpress within the Buyer Protection window and include your unboxing video and photos.
Do fakes exist for cheap classic Casios too?
Yes, although the savings are smaller. Check the store and the model code regardless of price.
