G-Shock GW-M5610U-1 Men's Solar Black Resin Sport Watch

This was purchased to replace a solar atomic Casio G-Shock I wore 24/7 for 15+ years that still works with the original battery! >> These are awesome watches because they’re super-accurate, thanks to the atomic signal timekeeping, and you don’t need to replace the batteries (solar charging). >> Out of the box it was set to the exact second and date. You never have to touch the time, as it’s synchronized to the atomic radio time signal. It only needs to be set on/off for daylight savings time. >> This is a solid looking watch, but it’s thin enough to fit under my button sleeve work shirts. It’s easy to read and has a fairly clean face, without the tiny, hard to read info-function circles of my last G shock. G-Shocks are perfect for active people who want to wear one watch and never take it off during work, sleep, showering, swimming, or play. G-Shocks take a beating and just keep performing. I never wear anything else.

Great watch! Simple design, solar-powered, and reliable. Only has one con: the automatic time adjustment works only when you wear it; if it’s off your wrist, it doesn’t adjust. Everything else is perfect — comfortable, stylish, and easy to use. Good for value of money, colors i like it, very light to wear, overall i am giving 5 star, i am so satisfied of quality.

Outstanding product. I'm 3 years in. It's the best watch for me. I wanted something that would just tell me the accurate time and live forever. The solar power is amazing, the battery takes such little energy to operate that in my experience you don't really need to purposely let it charge. It just does it on its own over time provided you spend at least some time in the sun. The radio time calibration works well, although you do need to place it in a spot where the radio waves won't get blocked. I occasionally place it on my thick desk and it doesn't always calibrate when I do that. But that's no big deal. There's minimal time drift with this watch, as long as your watch catches the radio signal at least once every couple weeks your time will stay very accurate. This is exactly what I was looking for: no frills, just a durable, accurate, lasts-pretty-much-forever kind of watch. Very satisfied 3 years in, it still looks pretty much the same as when I bought it.

The GWM5610 has become my everyday watch since I bought it back in April. It might not be the most stylish watch I own—though its retro '80s styling makes its own statement—but it's certainly the most versatile, and it's the watch that's on my wrist most of the time. The solar power and atomic synching is why I bought the watch, and for me, these two features make this watch more than worth the price of admission. The solar feature works as advertised. The power indicator was at "M" / Medium when the watch was delivered, but bumped up to "H" / High within a couple days, and has stayed there ever since. Granted, the battery won't last forever—maybe 10 to 15 years—but I'll worry about that around 2030. The atomic sync took a little trial-and-error; being on the east coast, I'm a long way away from the transmitter in Fort Collins. After a few days, I discovered that as long as the 12:00 position on the dial was pointed westward—the direction of the transmitter from my current location—the watch will "catch the wave" every night. On a trip out west, closer to the transmitter, the watch was much less particular about orientation—it even synced from a moving train during an overnight ride. I couldn't get it to sync from a cabin on a cruise ship, though—must be the thick metal hull. I always want my watch to be as accurate as possible, and the syncing accomplishes this. It's perfectly synced with my computer, my phone, the clocks in train stations and airports. On the cruise when it couldn't sync, it didn't drift more than a second off the actual time, so it looks like the accuracy is pretty good even without the sync. I've swam with the watch, snorkeled with it, showered with it, dropped it. It doesn't care. It's a G-Shock. The screen is easy to read. The backlight is nice and bright, though it only lasts for a second or two before it shuts off—shorter than some backlights on non-solar watches. The Auto El works for me, but isn't perfect—occasionally it doesn't go on when you flick your wrist, and occasionally it does go on when you don't need it to—so I generally leave it shut off, unless there's a reason why I need it to light up without physically pressing the button. As for other features, the World Time is useful for travel—whether it's you in another time zone, or someone you care about. The alarm is not super loud, and it only lasts for 10 seconds—but its loud enough to wake me up, and the snooze feature can make it sound again, just in case you don't hear it the first time it goes off. I use it when travelling. Stopwatch is nice to have; I don't use it that much. The countdown timer I use a lot. The watch is comfortable to wear. It's not overly bulky like some of the G-Shocks can be. I personally wouldn't want a bigger watch than this one. I like how it looks—it has a classic design. Not that I would wear it with a suit, but I don't have to wear one most of the time. In short, this watch does everything I need it to do. Thanks to the syncing feature, it keeps perfect time, and thanks to the solar feature and rugged construction, I can expect it to keep doing so. A lot of folks use smartwatches these days. Maybe I will upgrade to one someday myself. For now, though, many smartwatches lack an always-on display, or lack the rugged construction / water-resistance, or have to be charged daily, or require an Internet connection to maintain the correct time. Personally, I'll hold off on a smartwatch until they're a little more like my G-Shock. EDIT - 27 May 2022: I've had this watch for over 5 years now, and it has seen me through countless days at the office, plenty of travel, birth of a child, and a global pandemic. It still looks almost new. It catches radio signal almost every night—it will miss every so often in the winter months, but even then most nights it gets it. During the summer, the RCVD indicator is reliably lit up every day. I traveled with the 5610 recently to a place where it couldn't catch signal, so it didn't sync for a week. It drifted about +3.5 seconds compared to the atomic clock, which isn't bad at all. Note that if you order now, you'll get the GW-M5610-U as opposed to the GW-M5610 model (which is what I have). The newer "U" model has a LED backlight, which doesn't look quite as cool, but still works fine and uses less power. It also has the ability to display the date in DD.MM format, as opposed to MM.DD, and shows the time in Stopwatch and Countdown modes. There are a few extra timezones, and some other features (like swapping the World Time timezone and your home city time). I don't think it's worth the upgrade for me, but if you're buying new, you'll get these additional features, which I think makes the watch even more of a compelling buy than it already was.

I've had mine for over three years now. It just works. I don't have a problem with buying inexpensive watches, but when the time comes to change the battery, they usually break on me. I decided enough was enough and I wanted one that would be solar and atomic powered, so I wouldn't have to worry about batteries or time drifting. This is perfect for my needs. It's tough, water resistant, and solar and atomic powered. I don't need anything else. I don't want a smart watch; one more thing to baby and charge frequently. I also occasionally go to places where smart watches aren't allowed, so that would be a hassle. The price is exceedingly reasonable and has dropped a bit since I bought mine. If you just want a dependable watch that gives you the necessities and doesn't break the bank, this is it.

My favorite watch by far, I wear it everywhere, to the office, when I run my errands, outdoor adventures, gym, to the beach or pool, etc. I use this watch everyday, It is very durable and does not get scratched. I have hit this watch on everything and has not been damaged. I can it bump it on anything and not feel guilty. This is the best wach ever. it can be charged in the sun, so whenever you go outside with it, it will charged. I do not need to worry about replacing the battery. The time is always accurate, it is connected to attomic clocks around the world and updates multiple times a day! that means that this watch is always up to date. And it is also connected to whatever timezone you set it to, it will keep up with daylight savings always. If I had 1 watch to wear for the rest of my life, this would be it. It has everything I need, it is sturdy, always accurate, charges in the sun, and resistant to everything.

I love the watch and if I had to do it a second time (no pun intended) I would not change my purchase decision. On the other hand (no pun intended), Casio totally missed the mark (no pun intended) with the band. Overall, multi-band 6, solar, and durability are essential and this watch has all that. PROS: Display: The digital display on the watch itself is really nice. This is not MIP (memory in pixel) but is still very bold and crisp. The contrast against the background is sufficient to easily read the digits. Font size is good, even without my glasses. Accuracy: You can't get more accurate than atomic clock syncing. The multi-band 6 was a must-have for me -- I never want to wonder if my watch is fooling me with an inaccurate time and I hate obsessing over setting my watch to the exact second. I just want it done automatically, and this does it. Battery Life: The Tough Solar was my other must-have. I never want to be surprised with a dead battery, nor do I want to think about my battery life every time I trigger the watch light. I just want it to work always. Buttons: The buttons are a good middle-ground in that they can be pressed without needing a tool like a pen or paperclip but I am certain I will never hit a button accidentally, either. If I could fine-tune the buttons myself, I'd make them stick out slightly further so that they'd be slightly easier to press, but this is definitely within my acceptable range. Water Resistance: I don't dive or anything but I did wash it with soap and water. It handled the faucet water like a champ! CONS: The band seems durable but it's so undersized for this watch that it makes it all feel like a cheap toy. To be clear, the watch is very high quality but the band is too narrow, too short, and too light. I immediately replaced it with a nylon strap and I have a metal band on its way. (As in a bracelet, not Metallica) The alarm is very weak sounding. In a way, that doesn't bother me much because I don't rely on my watch alarm very often, but if I did I might be a bit disappointed. I have another G-SHOCK (GW-M500a) that is noticeably louder. I'm not sure if the quieter alarm is a design decision or a bug. VERDICT: If you want a digital watch, I don't think you could beat this package. It definitely ticks all the boxes (no pun intended). While there are a few aspects I would tweak if I had the power to do so, I think that all falls under personal preference. There's no reason not to get this watch as long as you like the band, or are willing to get a better aftermarket band. It looks cool and Casio has proven itself as a solid manufacturer. I expect this watch to be on my wrist for many years.

This model of G Shock is fantastic if you collect these Square models or want your first one, the look is criticized by some, the red stripe is meant to harken back to the original Square G Shock, some people dont like the look of the watch - but everything about this watch is fuctional....so that is that....its not really a watch for fashion type Casio people...this is a great EDC type of piece, a "one watch" piece more or less....I had standard model G Shock like this back in the 80's/ early 90's, primarily why I wanted this. I would probably say start out with the DW-5600 entry version if you have never had a Casio of this type before and want to get into one - its simpler, has the main features you need and nothing more, and its half the price on average of this Solar/ Atomic syncing model. But I am glad I got this version....If I had to grab one watch and only one....this would be the one - main reason - its slim but durable, light, and the solar battery means zero issues, water resistant for most average circumstances - example - you are going on a long trip, world travel, backpacking...this is a good solution...you just dont have to worry about it failing, running out of battery, etc. So, its is kind of worth the extra cost for the peace of mind, you will always have a watch. The World Time feature is great for travel - its always good to be able to track your home time or target destination time for planning and communicating with others back home, or for calling ahead to other destinations - you have to know business hours, best time to call etc....its a convenience thing - the watch has many time zones built in - so you just have to scroll thru and choose your 2nd time zone. The Multiband 6 (Atomic clock sync) is great - you know exactly what time it is...as long as you are synced up with a local frequency - the user manual talks alot about this topic - but you still can adjust the time manually - but once you are synced, the watch is supposed to be +- 15 seconds per month - better than most watches you could spend hundreds or thousands on. The watch attempts to sync up automatically each night....if you are within one of the 6 radio frequency ranges. The alarm is not that loud, but its functional. The countdown timer and stopwatch are there if you need those...standard more or less. Overall, this is a really intelligent purchase item, a great "one watch" if you just want a replacement timepiece and want one that does pretty much all you need a watch to do...and a little more. For G Shock collectors, you pretty much have to have a variation of this watch - its a classic. One nice detail also - the case back looks like a machined piece as opposed to stamped metal like the cheaper model and many other Casio models. The watch is slimmer and smaller than I expected - its understated and relatively compact compared to other large more recent Casio designs.....but, again, this is not a trendy bulky piece. Summary - if you are a world traveler, this watch would be a great choice. Or, if you want just one watch to serve you for the next several years, you wont need much more than this model of G Shock - you wont need a battery change for probably 10 years, maybe more....the one thing the manual does say and I dont see anyone talking about anywhere, if you are using the watch in water alot - you need to have it checked by a Casio approved technician/ shop every few years for seal replacement to ensure water resistance - the gaskets/ seals can wear out over time - I am sure this holds true for any G Shock or watch of this type.
