This model possesses Tough Solar and Multi-band 6 Atomic Timekeeping technology housed within an even slim profile octagonal case. Non-Stop Tough Solar Power provides energy via a small solar panel combined with a large-capacity rechargeable battery that enables a variety of energy-hungry functions to operate smoothly. Black resin band digital watch with neutral face.
With the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.
Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

The first thing I noticed about the watch is how much smaller, thinner, and lighter it is compared to round G-Shock versions I own. It is an excellent choice to wear under long sleeves and jackets because it easily fits underneath them with minimal interference. I will be using this watch in the winter months for daily wear due to its sleek profile. The second thing of note is the crisp clarity of the numbers in the positive LCD screen. It surpasses my Casio Pro-Trek PRW-3500 in regards to off-axis legibility even though the Pro-Trek’s digits are 50% larger than the GW-M5610’s. I am really impressed with how good this watch’s display is.
I find the strap fits comfortably on my 7-1/2 inch wrist. The light weight makes me forget that I am even wearing a watch at all. Contrary to the dozens of complaints from previous owners here on Amazon, my auto backlight function works perfectly fine even though I leave it shut off in order to conserve power. My watch was manufactured on January 8, 2015 so maybe Casio has finally fixed the issue with faulty backlight switches. There are several one star reviews of this watch here because of this issue and I honestly cannot understand how one can downgrade the rating of the entire watch due to one feature that most G-Shock users end up turning off anyway. The auto backlight duration unfortunately is not adjustable like my Pro-Trek and Gulfmaster. I would prefer the ability to lengthen it from 1 second to 3, but this is a minor nit.
The function buttons are all recessed into a protective niche on the side of the case so pressing them only works for me when I use the tip of a fingernail. Action is positive and appropriate for the pressing force I apply. The World Time, stop watch, and timer functions all work like other Casio digital watches and are intuitively accessed with mode button. The one complaint I do have is that the volume of the alarm signal is very weak and probably would not wake a person from a deep sleep. If Amazon’s star rating system would allow it, I would subtract a half star for this and would suggest not relying on this watch for important wake-ups and instead using the alarm from dedicated alarm clock or smart phone. Note that this isn’t any different than the other Casio solar-charged watches, so it may be a function of reduced battery capacity.
My watch arrived from Amazon with the power reserve showing at the Medium level. I put it out in the sun for about 30 minutes and the reading went to High. I set my home city, clicked Daylight Savings Time to the automatic setting, and synched the watch to the atomic clock signal in Ft. Collins without any trouble. Each evening just after midnight it synchs automatically so the watch always has an accurate time reading. I’ve had no issues with not receiving the signal but then again I live in a state bordering Colorado and all my atomic watches synch each day without fail.
This watch is a great heir to the spirit of the original G-Shock. It wears small and comfortably on the wrist, is tough as nails, cost about one-third of what the GW-5000 does, has the accuracy of atomic synching, should run for a decade or more on the original solar battery (note that all solar watches will need to have the rechargeable battery replaced as some time in their lives), and has a very clear and legible display.
As a long-time G-Shock owner, I have previously been drawn to only the round case models. I find it remarkable that after finally taking the plunge with this square case GW-M5610 that I have been absolutely delighted by this watch. It’s certainly not very flashy and has a nerdy charm of its own. No one in going to compliment you on it, but that’s all part of the fun of being a G-Shock fan. I now regret taking so long to come around to the Square Side and can recommend this watch most highly.
The things I like:
The watch is small for a G-shock, so if you are looking for something small and light, this is it.
The functionality is great. Solar powered, Automatic time, stop watch, count down timer, multiple alarms and a second time zone - perfect.
The illumination actually works on this watch. Very easy to see in the dark as the entire face lights. It is also water resistant to 600 feet - so you could scuba dive with this thing if you wanted. The solar power is great, because every time you have to open up the back of the case to replace the battery, you are compromising the water resistance and allowing contaminants inside. With this watch, you should never have to open the back.
I have had no problems with the automatic (EL) light tilt feature, (that has been a problem with so many others) so maybe Casio finally fixed this issue. I'm not sure I'll use it much, as it is too easy to tilt your watch and turn on the light when you don't need it, therefore wearing the battery down unnecessarily , but it's a nice feature just the same. My only complaint with the lighting is it isn't on long enough. (Only 1.5 seconds and you can't adjust the length of time) I have also seen that the auto EL feature requires you to twist your watch up at a very precise angle. Sometimes it is a bit fussy about turning on.
I like having the day, date and time visible on the front of the screen at a glance. The watch also has a power saving feature which turns off the LCD display when you aren't using it at night. This helps preserve your battery when not using the watch. The watch also has the battery level indicator right on the face which I like. Mine came with a Medium charge but I quickly was able to get it up to High by having it out in the sunlight for a couple of hours.
The watch is very easy to navigate and is very logically laid out. The printed instructions are very small so I suggest downloading the PDF file to enlarge the text. The instructions are very well written.
The Atomic synchronization with the Colorado WWVB time broadcast works great. I live in Florida and had no problem manually syncing the time during daylight hours while outside! It really surprised me that I was picking up a Level 3 signal on the East side of central Florida at 1:00 in the afternoon. This tells me the receiver in this watch is quite sensitive.
At night it synced the second attempt at 1:00am in less than 4 minutes. This is a great feature as I am always resetting my watches to the atomic clock anyway. This one does it for you each day, so you will always have nearly perfect time and will never have to change the date or time, unless you move. This is a great feature for a watch.
Being a HAM radio operator, let me tell you how this atomic clock signal works. First of all, it is a 60 kilohertz frequency, so you aren't going to get as reliable signal during daylight hours. The signal uses ground wave propagation and is usually easier to pick up at night as long wave signals work best after dark. The signal should be pretty strong just about everywhere during the early morning hours. (It's actually broadcast with 70,000 watts of power. Most Ham radio operators use 100 - 1000 watts to transmit around the world.) That's why the watch is programmed to start receiving at midnight. Place your watch near a window and you should pick it up pretty much anywhere in the USA. The only exception might be if you live in a large city near big buildings and heavy urban density which causes a lot of interference with the broadcast signal. Or you might live in a home with that has a lot of metal and electrical interference which some have reported in previous reviews. (I have actually had very good success picking up the signal outside during the day in manual mode (East Coast of Florida) and I live a long ways from the transmitter in Ft. Collins Colorado.
The watch is very rugged and I doubt I will ever wear it out the way I use it. I tend to like standard analog faced watches better, but this one is a great "kick around" watch that I can wear when I don't want to worry about being tough on my more expensive watches. The watch was reasonably priced compared to other G-Shocks while having both the Solar and Atomic syncing features. I really don't have a need for a barometer or altimeter, but I must admit, the compass and sunrise/sunset features would be nice. (Maybe on my next G-shock purchase?) But, you will end up with a much larger and bulkier watch as a trade-off for these extra features.
OK - so the watch is almost perfect - so why only 4 stars? Well, I'm sorry to say I don't like the resin band very much.
First of all, the band is too short. I have a medium wrist and it doesn't have a lot of slack. I usually have it on the forth hole.
Second, the band is not very comfortable to wear. I find it a bit stiff and it just doesn't conform to my wrist very well. I can live with it, but I'm going to try to replace it with another Casio band. I ordered one from the DW6900 to see if it is longer and more comfortable.
(Update 10-12-2015, just got the DW6900 band and it isn't any longer or any more supple - so back it goes)
I have also read that the GW5000 band is softer and more comfortable, (possibly made with a softer resin material) but is the same length and is expensive, so I'm not sure that's a better option. I could put adapters on it and wear a NATO type nylon strap, but I think it takes away from the watch's rugged looks.
If Casio had put a longer and more comfortable band on this it would be just about the perfect "knock around" watch. I'm very impressed with it so far and can live with the less than ideal band. I think the watch is a nice compromise between features, size and price.
I highly recommend it to others looking for a tough watch with a smaller profile (than other G-shocks) with a lot of advanced features.
Update Oct 15, 2015
Based on the reviews for the Casio DW5000 band, I ordered and received it. I don't know what it is, but the stock band is just not very comfortable and irritates my skin. Hopefully the replacement band will be more comfortable.
The Sync with the Atomic clock has worked perfectly each and every night, except one. You will find some nights where the radio propagation just isn't as strong for some reasons. Even if it misses a day or two, you aren't likely to be off more than a second as the quartz clock in this watch is very accurate.
I have a bit of buyer's remorse thinking I should have bought the Rangefinder 9400, since it has more toys. (Barometer, Altimeter, Compass, etc.), but I'm just not sure I would like the size of it. I don't camp or hunt so I really don't need those features. It's just the "toy" factor I am interested in. The 5610 is really nice for it's simplicity, reasonable price and smaller size. It does everything I need very well.
Update October 19 2015
Just received the GW5000 band. It is more rubbery, thinner and has more flex to it. In my opinion it is a bit more comfortable than the stock band that comes with this watch which has more of a hard plastic feel to it. The band I received was manufactured in Japan so I'm guessing it is more expensive to make. I'm very happy with the GW5000 band on this watch and had Casio put it on as stock, this watch would have gotten a 5 star rating from me.
