HOW IS THE SCREEN?
I had a really hard time deciding between this watch and the identical version with the regular screen. There are tons of youtube videos and pictures on the internet that try to describe the effectiveness and visibility of the inverted display, but cameras can be tricky. I wanted to offer my detailed experience of this watches inverted display. I will not be talking about the watches functions, for that you can reas the ~400 reviews on the other watch that is identical to this one, but with a regular display. I will say that the watch functions flawlessly. I bought this watch because I wanted the inverted display for style reasons and I thought that there were enough people online saying that the watch was easy enough to read. I though that the people who were reviewing the watch as not easy to read maybe had bad vision. But I was shocked at how dim the display actually is, (let me explain, I love this watch). When I first got it I was planning on returning it, Amazon has free returns, because it was SO dim. Like surprisingly dim. However, after using it for a few weeks I have found that there are practically no light situations in which I cannot read it. Let me explain. I broad daylight, or outside shadows, or a rainy day the watch is as clear as the picture on amazon. perfectly easy to read, just as any other watch at any reasonable angle of viewing. Indoors, in well lit situations, with a light overhead or a light nearby it is just as easy to read, not quite as clear as the picture, but it will be still extremely clear in these situations from any angle, have no doubt about this. However, in dim indoor lights, such as a romantic restaurant or a dimly lit cafe, or a room with a lamp in the corner the display is slightly less visible; the display in these situations can still be VERY easily read but it requires you to view the display straight on. It seems like the way the display works the numbers are dimmer when viewed at an angle in low light situations, but can still easily be read. Some situations where this watch cannot be read are at night outside with not much ambient light, or say you are indoors at night and in a room with no light on but you can still see because there is ambient light from a lamp in a different room you will not be able to read this watch. I have also found that if you cannot make out small print text on paper in your lighting situation then you will not be able to read this watch. However, why do I love this watch even when it sometimes cannot be read? Because of the auto EL feature. If you place the watch at a 0 degree angle and then turn the watch 40 degrees the watch face will light up, but only in low enough light situations, so it doesn't ruin the battery. This feature makes the watch to be able to be read in all light situations. Also, it is really well calibrated, much better than most smart watches these days; the watch will not come on with random shaking or while working with your hands, but only a very deliberate turning of the wrist. This feature has to be turned on manually, and will stay on after that. I hope this review has served to alleviate any concerns about whether the watch face is easy to read or not. My opinion is that it IS easy to read. But amazon has free returns if you think it isn't One more thing that is really cool is the atomic function. I have found that the watch is never more than about 1/10th of a second off the official time. Really cool!!!

Stylish and Indestructible
This is a great watch to wear every day, and you never have to worry about it failing on you. There's a reason Navy SEALS trust this brand. G Shock durability is unmatched, and the solar charging means this watch is more reliable than any other. It never loses the time because it syncs up via radio signals. Sure, the negative display can be hard to read at times (specifically in low light environments), but it has an auto-lightup feature that makes this a non-issue. You can enable this by holding the lightup button for a few seconds, and it will activate when you go to check the time and the watch senses darkness. While it lacks in visibility, it more than makes up for this with style. The negative display gives it a fantastic black-on-black look.

The classic Casio square...upgraded!
This is infamous Casio square, the very first G-Shock that started it all back in 1983. The 5610 continues that lineage, keeping the same classic square shape and offers one of the slimmest profiles of any G-Shock models today. Because of its classic timeless shape, its perfect for work or recreation, and doesn't look out of place in any occasion, even with a suit. This watch is perfect for anyone looking for a timepiece that's simple and unobtrusive. I would recommend this model as the first for anyone looking to start dipping their toes in the G-Shock world. This particular model is the 5610U (at least, the one I received from Amazon). The "U" is the updated model, I believe released in 2022, offering an upgraded LED light amongst other enhancements. What's great about this watch is that you essentially don't really need to do anything to it once you set it up. The Multi-Band 6 automatic radio time syncing syncs with the atomic clock signal put out in Fort Collins (in US) so you'll get the most accurate reading as long as you set up your home city. The watch syncs up nightly as long as you place it near a window. Other functions the watch has includes stopwatch, countdown timers, alarms, and world time (48 cities with 5 customizable city settings). This model also features power saving function where the watch turns off if left in the dark for a while, making it last even longer. Oh yeah, did I mention that its solar powered? As long as the watch gets to see some sun here and there, it will never run out of batteries. It doesn't even need to be directly in the sun, it works with any light source. Its essentially a set it and forget it watch. Never need to set the time and never need to swap or charge the battery. This is a watch that's designed and made to withstand any type of destruction or disaster. Who needs a smart watch? NOTE: Even though Amazon lists this watch as the "Japan" model (1BJF), it is NOT. This is actually the international model (1BJF) which may deter some purists looking for the "Made in Japan" printed on the underside. As far as I can tell, there are no noticeable differences in style or functionality except for where its made (international models are made in Thailand). Just something to keep in mind.

Great for indoor use, like in an office. Not great in low light or strong sunlight.
I have worn this Casio G-Shock GWM5610 for over a month. It has the "negative display", with amber colored numbers on a dark/black background. As others have mentioned, the numbers can be difficult to read under certain lighting circumstances. I notice it most when in BRIGHT sunlight. The time is difficult or impossible to read at times with just a glance. The screen washes out to appear mostly uniform black across it. I see a similar issue when in low light circumstances, like when watching TV at night in a darkened room with no overhead or nearby lighting. Thankfully the watch has a backlight that helps a lot in some cases. You hit the upper right button on the side of the watch and it backlights the screen with blue for maybe a second and a half or so. This is helpful in the dark and in sunlight. But that does require two-hands then to see the time. You can also set the backlight to pop on for a second automatically when you roll the watch toward your face, that way two hands are not required to turn on the light and check the time - however this feature does not work in bright light, so does not help you when outside in sunlight. When inside and with normal interior lighting around you, like in an office situation, this watch is GREAT. Its easy to read the time as long as you angle the watch face appropriately toward your eyes. The watch is good looking, and I like its dark appearance and golden numbers. Its solar powered, which I love, and I've not had any issues with it keeping up with the increased power needs presented by turning on the auto-light. It is amazingly accurate, and has not drifted at all. I have not played with the other uses for the watch, but have read that it does have an alarm and timer and other functions. I don't like the watch band as much as a "normal" watchband. It has caused some discomfort both due to the polymer material apparently itching and the buckle poking me more than is normal. I always wear a watch, like 100% of the time, and I generally don't have these issues with any of my other watches but none of my other watches have a polymer watchband. To address this I will likely to transition the watch to a more bracelet-like watchband like the V2 version being used on some other GWM510 models or a metal version, or perhaps a Zulu band. I bought this watch for $100 during a sale in 2022. Overall I like the watch and I would buy it again at that price. I work in an office and am not bothered by the challenges with seeing the time in bright sunlight or darkness. I can hit the backlight button in those cases, or just check my phone. If you live or work alot in bright sunlight or darkness I probably would not recommend this watch for you. I would suggest you lookat one of the normal displays rather than a negative display, or maybe an analog version of a G-Shock.

Wow! This watch is amazing!
I bought this watch to use for work since I don’t want to scratch up my expensive $800 Apple watch. After wearing it for a week I started to like it more than the smart watches that have all the bells and whistles. This watch is durable, dependable, and good looking. The convenience of having a watch that is almost indestructible, never has dead batteries, and always has the correct time with no input is HUGE. I can’t think of another watch that is like this one. It’s just what you need and nothing more. No annoying software updates, worrying about dead batteries, or bugs. I have gotten more excitement out of this simple watch then any smart watch I have owned. I think I even read somewhere that this watch or one of their watches similar to this one made it into the Guinness World Records. To me this watch has 10 times more value then most other watches you will ever see even if this is not the most expensive option. One feature I noticed that I did not see before is how it conserves power by turning off the face when left untouched overnight. As soon as you pick it up in the morning the screen turns back on and will stay on the rest of the day while it is on your wrist. I have not had any issue reading the numbers with the black background. I wouldn’t say it’s the easiest to read of all watches but it’s good enough. My only complaint (and it’s really not that big of an issue) is that the paper instructions in the box are all in Chinese. You should be able to look up instructions in English online if you need too. Hope this helps anyone with their decision on purchasing this watch! I give it a 10 out of 10 :)

Awesome watch!!!! 5 stars.
This watch is awesome!! Well worth the money! Tough, blacked out, and solar. No need to replace the battery every 2 years losing the water-seal. This watch is from Japan, and came in a cool box with a small pillow. The watch has a soft rubber band, its feels very smooth and comfortable, unlike those HORRIBLE RESIN and SILICON bands. Today was 92 and I didn't even notice the band. Even though its blacked out, it is easy to read the time and has a light for darkness. Some people have whined about the display, that's why they have pictures on Amazon before you buy it. I had the DW5600MS-1CR but returned it when Casio said the battery only last 2 years. Then when its replaced you might lose the seal. For $50 more I got this incredible watch. I am still amazed how comfortable the rubber band is, I don't understand why they use resin bands, they are very uncomfortable in the heat, and when its cold they stiffen up.The buttons on this watch are very easy to use and your fingers wont go numb from setting the watch. The blacked out face looks great, its one bad a$$ watch. It came with a high charge and I put it in direct sunlight for 20 minutes to keep it highly charged. I looked at Seiko solar and Citizen Eco Drive, but I know they cant handle being under water, and you have to be careful not to crack the watch face. For $141 it is well worth the price. It also has a great size, and a perfect fit. The display size is very easy to read, and simple to set, you don't need a degree from MIT to figure out the watch. This watch deserves 6 stars and the seller is great as well. If you are going to spend $100 on a Gshock, spend the extra money and get this watch, you wont regret it.

Great G-Shock...but not Japanese Market
I had my eye on this G-Shock for a while now, really liked the all black look, minimal colors on the text, atomic clock, and the negative display. The fact that it was a Japanese market item made it a bit more unique, and the price reflected this. They all came from Japanese sellers for close to $200. I kept coming back trying to decide if I really wanted to spend that much on this watch. Well, one cay, I happened to notice in the "other sellers" section, it was listed at $105 from Amazon directly. Unsure how this could possibly be, I decided to pull the trigger anyway and return it if anything looked suspicious. It was not scheduled to be in-stock until April, but was happy to see an update that it was arriving this week. Got it today and am happy to report that the watch is ALMOST everything as advertised. I'm not going to comment on its features, durability, or day-to day usage as that has already been covered elsewhere. I have no doubt that it will meet all expectations in that regard, and if you are a G-shock fan, you will probably be satisfied. It's clearly a genuine G-Shock, it came with all the Casio packaging materials, manuals, warranty card, and metal hexagon tin. Made in Thailand, not China. The watch itself looks and feels great. The only thing that might give some buyers pause is that it's not the GW-M5610-1BJF (indicating Japanese market), rather it's GW-M5610-1BCR (indicating worldwide market). My suspicion is that Casio recently released this model to be available in the US, which is how Amazon got the ability to sell it directly. It now retails for $140, which is less than you would have paid for a JDM model, but is still more than many similar 5610s. So all in all, I'm happy with the watch. The negative LCD is not that difficult for me to read, in fact, when held at the correct angle, it's extremely legible. The size is perfect, it feels great - light but substantial (if that makes sense). Sure it's not the Japanese version of the watch, but that doesn't matter to me nearly as much to me as it being about half the cost. However, if you really want the BJF model, you probably still need to get it from a 3rd party seller.

It’s a G-Shock. Enough said.
Excellent watch and exactly the quality you’d expect from a G-Shock. You can always depend on its durability, features, ease of use. I know a lot of people don’t like the negative display, but I’m personally a fan. This being a tough solar watch, I’m not afraid to use the light more often than I would on a regular battery operated G-Shock. Having multi band 6 is great, never have to worry about setting the time or it being off as it updates every night. All around excellent watch for the money and love having it in my collection. Highly recommended!

Excelente opción para uso diario y discreción
El reloj es una buena opción para tener de colección, desgraciadamente la pantalla negativa no se logra percibir bien en un lugar cerrado o con poca luz, al aire libre se ve maravilloso, que es para lo que está diseñado; el contacto directo con la luz, ahí la pantalla negativa adquiere una belleza que depende el gusto de cada uno si le es agradable o no. Aunque le cuesta trabajo recibir la señal (yo vivo en el estado de México) me imagino que alguien más al norte del país se le hará menos complicado el proceso de recibir la información. A simple vista se aprecia más delgado y pequeño que otros g shock, yo tengo el clásico dw5600 ya con varios años de uso rudo y en la foto puede verse como se aprecia más pequeño este GW La iluminación efectivamente no es El Electroluminescent, el percibir el foquito que enciende y da luz le quita la belleza al reloj, pero me imagino que es debido al módulo con el que está diseñado este reloj, me parece que el módulo que tiene la luz EL es de otro año de fabricación, puedo estar equivocado en este dato pero el que me tocó a mí tiene esa luz que veo en las reseñas a muchos les incomoda. La calidad de la resina se siente bien al tacto, tiene una sensación más suave a la que recuerdo de otros g shock, no es premium pero por el precio es un gusto al tacto. La parte trasera no tiene ningún fallo y ya tiene contacto con el reloj, me hace pensar que este diseño de la tapa trasera le ayuda a tener un mejor agarre a la muñeca, lo que lo hace sentir más pequeño, y con los normales o como el gw5000 que tiene tapa roscada genera esa sensación de brusquedad. Yo estoy encantado con el reloj, y por el precio al que lo encontré (1900 aprox), no lo duden y agregenlo a su colección

Very slick looking watch, and super comfortable to wear.
Watch came exactly as hoped for. Takes a little bit to learn all the functions, nothing is complicated, just lots of features packed into a very simple design. I get lots of comments on it, and I appreciate that it can't be found everywhere. Can be a bit tough to read in low light, but there is a feature that can help with that as well. Ultimately, it is a great addition.
