Trying to learn how to spot fake Casio G-Shock watches? Just want to know whether you are looking at a real or fake Casio G-Shock watch?

Well, if that’s what you have in mind, then you are in the right place, as just by reading this fake vs real Casio G-Shock guide, you are going to easily know how to authenticate these tough watches.

With each step of this guide, you are going to see reference real vs fake Casio G-Shock images that will help you easily identify the flaws on the fake watch, as well as the properly defined details on the genuine pieces.

To put it shortly, the fastest way to spot fake Casio G-Shock watches is to take the 3 button test, as the replica Casio G-Shock watches very often do not have this function in place, therefore leaving a gap in terms of attention and quality between the authentic vs fake Casio G-Shock watches.

How to spot fake Casio G-Shock watches

Step 1: Authentic vs replica Casio G-Shock 3 button test

Just as how we’ve previously mentioned, we consider the 3 button test as a very reliable method on how to spot fake Casio G-Shock watches.

And so, keep in mind that our recommendation is to never skip checking this function since it is the go-to way on how to spot fake Casio G-Shock watches.

In the video with the real vs fake Casio G-Shock watches above, we have shown you how the 3 button test should work.

If you press the specific 3 buttons (A, B and D – in other words, the button on the left side and the bottom button on the right side, in most G-Shock models) on the G-Shock at the same time, its display will show all the pixels on.

Furthermore, if you press the 4th button (button C – top right button) you can cycle through this hidden menu and ultimately get to see the module/movement number.

Step 2: Inspect the case back engravings on your Casio G-Shock watch

For the second step of the guide on how to spot fake Casio G-Shock watches, we are going to have a look at the real vs fake Casio G-Shock for their case-back engravings.

First things first, let’s quickly check the genuine vs replica Casio G-Shock image below, and after that, we will explain the flaws on the fake watch, as well as the details on the genuine piece.

how to see fake casio g-shock

As you can see in the image with the fake vs real Casio G-Shock watches above, we have pointed out how the fake watch has its engravings at the wrong font-weight.

In fact, the fake watch has its “SHOCK RESIST” inscription in the middle of the watch being too thin, while the authentic watch has its text thicker.

That is because the fake watch has its text fit too little deep inside the metal case, therefore having this thin look, while the authentic watch has its text thicker because it is engraved deeper on the metal case.

Then, looking at the rounded inscriptions all around the watch, the fake item has its text too thick, while the authentic watch has all of its curvy inscriptions thinner.

Step 3: Check the packaging of your Casio G-Shock watch

Going to the third step of the guide on how to spot fake Casio G-Shock watches, we are going to look at the real vs fake G-Shock Casio watches for their packaging.

Just as always, let’s quickly inspect the image with the authentic vs replica Casio G-Shock watches below.

In the image with the real vs fake Casio G-Shock watches above, we have pointed out how the authentic G-Shock has its aluminum case encased in a cardboard box.

On the other hand, a lot of the fake Casio G-Shock watches don’t have their aluminum case in a cardboard box, and they come aside of the watch without any packaging.

Step 4: Inspect the inscriptions on the manual of your watch

Proceeding to the fourth way on how to spot fake Casio G-Shock watches, we are now going to look at the real vs fake Casio watches for their manual.

The manual is the little book that gives you information on how to use all functions of your Casio G-Shock. Now, let’s have a look at the comparison between the authentic vs replica Casio G-Shocks.

In most cases, the replica Casio G-Shock watches will have their manual with more than 50% of the text written in Chinese, and that’s something not to be seen on the genuine manuals.

The authentic Casio G-Shock watches must have the code matching the one on the MRP sticker, and at the same time, the code can also be checked on Casio’s website.

Keep in mind that the authentic Casio G-Shock watches must have their matching model number on the box, the manual and on the rear side of the watch’s case. Also, some G-Shock replicas don’t even offer a manual, or at least not for the correct model number.

The steps we’ve written so far are the best ways to authenticate this item.

The next few steps are still reliable signs of authenticity, but are for non-top-versions of replicas available for this item. We recommend sticking to the steps we’ve explained above to make sure you’re not drawing the wrong conclusions.

Step 5: Examine the weight of your Casio G-Shock watch

Going to the fifth step of the guide on how to spot fake Casio G-Shock watches, we will now talk about the real vs fake Casio G-Shocks for their weight.

The watch’s specific weight can be found in multiple reliable sources over the Internet, including authorized dealers, so it can be cross-checked with the item being authenticated.

Make sure the weight of the watch you are authenticating is matching the official weight description that can be found within authorized dealers of the Casio G-Shock.

Step 6: Check the clasp of your Casio G-Shock watch

As for the sixth method on how to spot fake Casio G-Shock watches, we are going to look at the real vs fake Casio G-Shocks for their clasps.

The clasp is the little feature of the Casio G-Shock that helps you close the strap, and so, it is what ties the watch to your hand.

In the image with the fake vs real Casio G-Shock watches above, we have pointed out how the fake watch’s clasp is missing the inscription which is present on the genuine item.

Looking at the authentic watch’s clasp, you can see how there is the “CASIO” text engraved on the inner side of the the metal clasp.

Step 7: Verify the lume effect on the Casio G-Shock watch

Proceeding to the seventh way on how to spot fake Casio G-Shock watches, we are going to look at the fake vs real Casio G-Shocks for their lume effect.

The lume effect represents the chemicals that are available on specific elements of the watch and that light up once they are charged, in order to help you easily tell the time when you are in a dark environment.

g-shock fake vs real

In the image with the real vs fake Casio G-Shock watches above, we have pointed out how the authentic watch has its hours and minute hands lit, as they were charged and properly shining in the dark.

The replica watch doesn’t have its lume effect, as the feature is completely missing on the fake wristwatch. Therefore, as much as you’d try to charge the fake watch as in the image above, it won’t light and shine.

Step 8: Inspect the names mentioned on your watch

Going to the eighth method on how to spot fake Casio G-Shock watches, we will now have a look at the real vs fake Casio G-Shock watches for its inscriptions on the bezel and dial.

Even though it may seem like a simple spot to check, remember that spots like this can easily tell you the authenticity of a Casio G-Shock, as replica manufacturers don’t always pay the right amount of attention to these small details.

fake vs real casio g-shok

In the image with the real vs fake Casio G-Shock watches above, we have pointed out how the fake watch has the wrong inscriptions.

In fact, at the top of the bezel, the fake watch says “S-SHOCK” instead of “G-SHOCK”, and at the top of the dial, there it says “SKMEI” instead of the authentic watch’s “CASIO / MULTI BAND 6” text.

Looking at the word “MODE”, we have observed how the fake watch has its text too thick, too big and wider than the authentic watch’s text.

Back to the authentic Casio G-Shock watch, you can see how its “MODE” inscription is thinner and smaller than the same inscription on the fake watch.

Step 9: Real vs fake Casio G-Shock hand colors

For the ninth method on how to spot fake Casio G-Shock watches, we are going to look at the hands of the real vs fake Casio watches.

In most cases, the counterfeit-manufactured Casio G-Shock watches have their hands tip colored in the wrong shade.

In the image with the fake vs real Casio G-Shocks above, we have pointed out how the fake watch’s hand uses one single color for the entire length of its hands.

The genuine Casio G-Shock watch has its hands grey, and the tip at the top of the hands are coloured in blue, unlike the fake watch’s hands which have just one colour for the whole metal, instead of having only the tip coloured.

Step 10: Authenticate the 12 o’clock pointer on the G-Shock

Proceeding to the tenth method on how to spot fake Casio G-Shock watches, we are going to look at the real vs fake Casio G-Shocks for their 12 o’clock hour mark, at the top of the watches.

casio g-shock authentication guide

What we have pointed out in the real vs fake Casio G-Shock image above is the fact that the fake watch’s pointer at 12 o’clock has triangle-shaped edges.

The authentic Casio G-Shock watch’s pointer at 12 o’clock has square edges, and so, it is shaped almost like a square, unlike the fake watch’s triangle-shaped pointer.

Step 11: Test the precision of your of your Casio G-Shock watch

Moving forward to the eleventh and the last step of the guide on how to spot fake Casio G-Shock watches, we are going to talk about the precision of the watches while showing the time.

The authentic watches must have a precision of ±15 seconds per month, while some of the fake watches have present differences when it comes to time precision.

So, after inspecting your watch for a month, or using specific tools (like mobile apps, or a tool named timegrapher), you should notice that if it is a genuine item it will have a delay of maximum plus or minus 15 seconds in that month – which comes down to ± 0.5 seconds/24 hours.
