Casio G-Shock GW-M5610 Hands-On Review

Are you thinking of buying the classic Casio G-Shock GW-M5610? Don’t think about it too much, it’s one of the best G-Shock for quality price at the moment. You just have to see what suits your needs.

We are going to tell you what this Casio G-Shock GW-M5610 has and what it does not have, one of the G-Shocks with a more classic design and a good number of features that make it perfect to start in this world: solar charging, radio time synchronization, automatic light, 200m water resistance, shock-resistant…and relatively small for a G-Shock, making it perfect for small wrists.

  • I have tested the Casio GW-5610-1CR model with a negative screen and the Casio GW-M5610-1ER with a positive screen.

The two watches are excellent, the one with the inverted screen is more elegant and has a more modern style, but the visibility and poise of the positive model are unrivaled. It has to be in your G-shock collection.

Right now you can buy it in its black/grey, black/dark gray, and black/black version: it changes the color of the screen…. and the first thing you can ask yourself is what the screen looks like in negative (black).

Well, the design is beautiful both in its negative and positive versions, that’s why I bought these two watches, but the truth is that the screen of the negative version is not the best looking, especially if we compare it with the Casio DW-5600BB model.

If you need good visibility of the screen and its digits, don’t hesitate, the Casio GW-M5610-1ER is the best option.

That said, you’re only going to have trouble seeing the numbers in low-light situations, which is easily fixed by turning on the auto light.

It is a watch with a classic square design and quite small if we take into account, other models.

Perfect for medium/large wrists. I have an 18.5cm wrist, so you can get an idea of ​​how it will look on you by looking at the following photo of the model with a negative screen:

Or the following photo of the model with a positive screen:

The width of the resin strap is 23 mm and it weighs 50 grams. It has a case diameter of 43mm and a thickness of 23mm. If you have a very large wrist, it will be small in it. It doesn’t draw much attention.

It is a really comfortable watch. You don’t even realize you’re wearing it. Doesn’t even bother sleeping.

The dial is not overwhelming and shows the essentials: the day of the week and date at the top, and time at the bottom, with two small bands in the lower area where we can see what alarms we have activated and how the battery charge is going.

In the gaps that remain, different symbols will appear, such as PS, radio synchronization, etc…

Buttons? Well, we have 4 and, in my case, they are not particularly easy to press, especially at night in low light. I may have very big fingers… In the Rangeman 9400 that I have, I don’t have so many problems.

Light? Very good. it lights up the entire screen smoothly and everything looks correct.

It does not have sensors such as temperature, compass, barometer, or altimeter, but that is reserved for slightly more expensive models such as some Gravitymaster watches.

Casio G-Shock GW-M5610 setup

1.-Download the manual

The manual that comes with the watch is usually the reduced version and does not give you all the options to configure it correctly, especially in the case of radio synchronization of the time.

Just visit the web: and look on the back of your watch for a four-digit number surrounded by a rectangle, the module number. 

You put it on, and normally you can usually download the quick instruction manual of the watch and the extended manual with all the things you can do with it (operation guide).

In the case of this model, it comes like manually setting the time with the atomic synchronization function, and many other things, such as what all the screen icons mean like RCVD, L3, PS, RC! etc…

2.-Set the city where you are

It is the first thing to do so that the clock can automatically synchronize the time correctly the following night.

In normal time mode, you hold down the A button (first top left) until the city code starts flashing. You press D (east) and B (west) to select the city code (buttons to the right of the clock).

This is the most important, but since you are in this set menu you can keep pressing C (lower left button) to set the correct time and other options.

3.-Will the time be synchronized by radio? How to change the time of a G-Shock manually

Can you start the sync manually? Effectively. Go to timekeeping mode, and hold down the D button until the RCVD indicator starts flashing on the display (RC! appears in a box meanwhile).

Now you just have to wait and see if the ERR (Error) icon appears or if RCVD stays on the screen (the synchronization is correct).

  • On the clock screen, you will see the signal strength: L1, L2, and L3, with L3 being the strongest.

Don’t despair if you can’t get the clock to sync over the radio the first time. Try it at night, from 00:00 or 05:00: put it in a window facing North. The antenna is located at 12 o’clock, so make sure you direct it well and leave the clock upright.

Do not leave it next to electronic devices, try not to have large buildings around it, and try on clear days. In the online instructions, you have more tricks.

The word RCVD appears on the main screen (upper left corner) if the time synchronization is correct by radio frequency

How do you know it has synced the time correctly the next day? Easy, the word RCVD appears on the main screen (upper left corner) (RCVD is only kept on the screen on the day on which the synchronization has occurred correctly. If it fails the following night, it disappears).

What if you want to manually set the time on your G-Shock? Well, it can also be done. You know, you have to use a combination of buttons.

To set the time and date on your Casio G-Shock, simply press and hold the A (Settings) button for about 2 seconds, then keep pressing C until the setting you want to change starts flashing. With D and B you can change the hour, minutes, and seconds. Press A to exit the Settings screen.

In the following entry you can find the complete description for each type of G-Shock watch:

How to Change the Time on a Casio G-Shock

4.-Rest of functions and configuration of the Casio G-Shock GW-M5610

The rest is all simpler and you can follow the manual without much problem. I am not going to detail how the 5 alarms are activated or how the world time is changed to different cities or how the stopwatch and countdown timer works… It is a simple watch to use knowing the correct combination of buttons.

But if I am going to indicate how to activate a very interesting thing, the automatic backlight lasts 1.5 seconds. It is not activated by default and I think it is essential.

I don’t know if it will be your case, but the buttons on this watch are a bit small for my fingers, so activating the light on the screen at night by pressing button (B) is somewhat complicated for me, so I prefer to activate the auto light function that starts if you move the watch to a position parallel to the ground and then tilt it towards you at an angle greater than 40 degrees.

  • To activate this function you just have to hold down the B button until A.EL appears on the screen. And that’s it. very easy.

It is also interesting to check that the energy-saving function is activated: the PS icon must appear on the screen. It’s enabled by default…

  1. In the Timekeeping Mode, you hold down the A button until the city code starts flashing.
  2. You press the C button 9 times until the power saving on/off screen appears.
  3. You press the D button to toggle between ON and OFF.
  4. You press the A button to exit the setting screen.

The solar charge of the Casio G-Shock GW-5610

It is one of the main reasons to buy this model and not a cheaper one. Using a Casio Solar (Tough Solar) means you won’t have to change the battery for many, many years. It is estimated that between 10 and 20 years, depending on the model.

You just have to be careful to have it well-fed with light. To do this, you have to give it full sun or a fluorescent light… Sunlight is better because it charges faster.

On the screen, you can see the charge level indication: L, M, H (Low, Medium, High). In my case, it has never dropped from high.

How long does it take to charge? These are the approximate times:

Outdoor sunlight (50,000 lux) 5 minutes

Sunlight through a window (10,000 lux) 24 minutes

Daylight through a window on a cloudy day (5,000 lux) 48 minutes

Interior fluorescent lighting (500 lux) 8 hours

Conclusion: Is the Casio G-Shock GW-M5610 worth buying?

I am quite a fan of this model to wear it on a daily basis. The synthetic resin case and strap are really comfortable, and you never feel like you have the watch on. Solar charging works perfectly, and Multiband 6 synchronization… well, it depends on where you live, but it’s a good option to always have the clock on time, although it’s not essential.

Casio GW-M5610-1ER vs Casio GW- M5610-1CR

The negative version screen ( Casio GW-M5610-1CR ) is not one of the best seen in certain situations, but it is not something that prevents you from enjoying this Casio either. You can always buy the classic version, the Casio GW-M5610-1ER with a positive screen. The automatic light is a great addition.

It has alarms, a stopwatch, a timer, water resistance up to 200 meters, and is resistant to falls. Typical in a G-Shock. In contrast, it does not have more advanced sensors such as temperature, compass, barometer, or altimeter… and it is not as resistant as a GW-9400 Rangeman to dust or mud, but they are not designed for the same audience.

It is one of the G-Shock watches with the best value for money at the moment.

What if you want a round Casio G-Shock watch with a simple module? The recommendation is clear, the Casio G-Shock DW-6900.

In favor:

  • Excellent quality-price
  • Very light and easy to use
  • Solar charging and Multiband 6
  • Classic and sober design


  • The negative display model is poorly readable in many situations. The model with a positive screen is perfect in every way.
