Born from a dream of “creating a watch that never breaks.” It was over 30 years ago, a CASIO engineer won the battle against the laws of nature. He designed a watch that would resist centrifugal and impact forces, as well as high water pressure. Since then, the name G-SHOCK has become a byword for independence and pushing the limits.

G-SHOCK watches are the most durable digital and analog-digital watches in the industry, trusted by military personnel, law enforcement, surfers and outdoor enthusiasts around the world. Along with this, G-SHOCK is highly touted in the fashion world, worn by icons in hip-hop, sports, and design. With limited edition collaborations being released often, you can always find a G-SHOCK that matches your personality and style.

    I bought this watch for Basic Combat Training and Advanced Individual Training as a Combat Engineer in the US Army and it has done nothing but impress. If you don’t know anything about Combat engineering, that’s understandable, as neither did I about a year ago. But, know this: the training to become one is pretty darn tough. This watch never left my wrist and it still looks brand new, less one very small scratch on the crystal (you have to cock the watch at just the right angle to the light to see it, so most of the time I forget that it’s there). A lot of my buddies there had cheaper watches ($40-60, non g shock watches) and all but a few were completely destroyed by scratches or body damage by the end of the cycle, but this little baby did great and never lost perfect time. I can not recommend this watch highly enough for anyone looking for a very durable watch that can keep up with anything you throw at it.

    I thought I would let everyone know how how long the battery on this solar watch lasts, considering it is a solar watch. I was curious when I bought it so if anyone else is curious here is a real world review. First of all, I’m writing this not because the watch stopped working, THE BATTERY IS STILL GOOD. I’m writing it because just got curious and looked into my Amazon Orders to see when I bought it. I bought the watch in 2010 and it’s 2017 now. So AT LEAST 7 years, because the watch still works fine. I will say though, while I did wear the watch when I first bought it (for about 6 months) I then bought another watch that I started to wear and have rarely worn this watch since. I still like the watch but for whatever reason have not been actively wearing it. So the next big question is:HOW HAS IT BEEN STORED FOR THE PAST 6+ YEARS???I figured it would be better for the battery if the watch stayed fully charged. So for the past 6+ years it has ALWAYS been near a light source. Never in direct sunlight though. I’ve always had the face pointed towards a window somewhere between 4-10 feet with lots of light light.I’m really curious how long it will last now. In the future I will try and remember to post updates if I remember. I’ll also try to remember when to post when it eventually dies out.

    I’ve had this watch for almost a month now. The convenience of the solar power coupled with radio controlled time keeping makes it virtually worry free.Looks – I’m over six feet tall, but not very large for my height. This watch fits fine and has a subtle and understated look. I teach high school students, who notice most things, and maybe one student has commented on the new watch. It works with anything I wear for work typically, although I plan to wear a stainless watch when I have to dress up in a suit. Not flashy, but certainly not ugly.Features – for the price, features are excellent and reasonably simple to use. Multiple alarms, including one “snoozable” alarm, radio time keeping which is updated nightly, solar charged battery, stopwatch precise to hundredths, countdown time, secondary time zone, for when traveling. It’s also got a day of the week and month/date display as well. 200 m water resistance, shock resistance, and a backlight display round out the watch’s main features.Experience – extremely positive! The watch has updated the time every night through the radio. It keeps a record of when it was last updated so you can check. The solar battery indicator was on “mid” when I received it, and stayed that way for a couple of weeks. After a day of yard work and watching a soccer game in the sun it moved to high level charge, where it’s been ever since.Summary – excellent, worry free watch. Keeps accurate time, date, and month with a few other features. Would purchase again and recommend to a friend.

    This watch is based on the original DW-6900 model, G-Shock’s best-selling case design. However, unlike the DW-6900, it is solar powered with multi-band 6 atomic timekeeping.I bought this watch for its great all around functionality and durability. You just cannot beat it for the price. With that being said, and if price is not so much of a concern to you, and you want a thicker watch with some additional features such as a thermometer and a compass, you might want to look at the G-Shock Mudman models. However, while all Mudmans are solar powered, not all of them feature multi-band 6 atomic timekeeping like this one.SOLAR BATTERY CHARGEDo not get frustrated if at first you receive this watch and the Battery Power Indicator will not go to high while indoors and exposed to light. That is what happened to me the first 2 or 3 days trying to raise the charge from medium to high near an indoor window. My advice is to keep a positive attitude about it. There is nothing wrong with the solar battery. Simply get the watch into outdoor sunlight for a few hours. I finally wisened up and did that on the third day, and the Battery Power Indicator went to high. That was 34 days ago, and it has been on high ever since.OPERATIONThis watch is extremely simple to operate. It has no unnecessary thermometer or compass which, to the average person, are not worth the hassle of setting up, especially since the accuracy of those features is always in question.I like the front button for illumination of the light. Many G-Shock models have no front button instead utilizing the upper right side button for light illumination.Further, I like the ability to scroll both east and west through the 48 city codes this watch offers. Not all G-Shocks can scroll in both directions. Sometimes they are limited to eastward scrolling due to configuration of the module with the style. But the capability of both east and west scrolling is far less clumsy.If you want to further check out operation, I suggest researching the online Operation Guide where you will find very clear and concise product information.Important Tip: The times displayed in the Timekeeping Mode and World Time Mode are linked. Because of this, be sure you select a Home City (the city where you normally will use the watch) BEFORE you set the time and the date. Sometimes people do not read the Operation Guide and initially get hung up on operation not realizing this.INSCRIPTIONon Stainless Steel BackST. STEEL BACK – MADE IN THAILAND – Y – WATER RESIST 20 BAR – CASIO – 3179 – GW-6900 – SHOCK RESIST – SHOCK ABSORBING STRUCTUREAlso on the stainless steel back is an alphanumeric inscription or stamp which I believe to be a serial number.INSCRIPTIONon Watchband ClaspCASIO THAILANDCALENDARThe watch is programmed to automatically adjust the date of the month for the varying lengths of months as well as leap years to the year 2099.CRYSTALThis watch has a MINERAL crystal which is one of 3 crystal types commonly used in watches. For comparison of those types, I have described each of them below:1. Acrylic crystal is an inexpensive plastic that allows shallow scratches to be buffed out.2. MINERAL crystal (this watch) is composed of several elements that are heat-treated to create an unusual hardness that helps resist scratches.3. Sapphire is the most expensive and durable crystal, approximately 3 times harder than mineral crystals and 20 times harder than acrylic crystals.PHOTOSThe 5 photos included with this review are not mine.

    I needed a replacement for a Timex Expedition that had lost some functionality (light/chimes). After reading the reviews I has a little hesitation since many talked about the battery never reaching a “high” charge. I’ve had it for about two weeks and after letting it sit in the sun for about 4hrs at work it’s never left the “high” charge. The display is easy to read from any angle and even when wearing polarized sunglasses. The only con is that the alarms are not very loud and do not last very long; only about 10 seconds but I don’ use them very often so it’s not enough of a concern to drop to 4 stars. The watch has a good weight which I’m hoping lends to it’s legendary G-Shock durability.It keeps excellent time and is even in sync down to the second with the atomic clocks at work. The first manual sync failed but I just waited a minute or two, tried again and it worked. I like that you can also check the last update to see if it worked or not but the auto update just after midnight has been flawless.

    hey everyone. just checking in here. it’s February of 2018. I purchased my watch in 2013! 5 years and still running as good as new. it has been a daily wear item and has held up to mountain bike crashes, swimming in the ocean and daily baths. I have never had an issue with it. it is beat up, scared and scratched. it’s been my trustworthy adventure buddy for so long I had forgot when I purchased it. if I lost this watch, I would replace it with the same model without hesitation.

    I bought this watch here on Amazon in April of 2014 and it is now Sept 2019. This watch is in its 6th year of being on my wrist everyday. This watch has been in several oceans, several countries and I work offshore in a very dirty, salty environment. I don’t sit on the bridge in the air conditioning. I’m out in the mud and the salt. It has kept time nearly perfectly, especially when it is connected to Auto-Receive, which I don’t keep on all the time because I like to change the time manually when I cross time zones and not have the watch do its own thing and not wake me up on time, which has happened. When Auto-Receive is turned on it adjusts anatomically to the correct time. I use all the functions of the watch pretty regularly and it is quite easy to change time zones while travelling, which I do every month. I also keep the manual in a zip lock and take it everywhere with me so that I can keep the watch set up the way I want it. There are also manuals for every G-Shock on line if they are needed.One of my favorite features is the snooze alarm. It goes off, if I remember correctly, every 5 minutes for 10 seconds and doesn’t require you to stop it by pulling your head off the pillow and pushing a button. It goes off 7 times before it stops and it usually only takes me 3 or 4 snoozes to get going. I don’t use it all the time but it’s nice if you hate getting up for work and want to eaze out of bed every now and then.After 5 years of constant, every-single-day wear the matte finish is completely polished now. There are scratches and gouges all over the watch bezel and band including some faint dry-rot where the buckle is always fastened. All of the older gouges have that worn, “melted” look from the sharp edges being worn and polished down. I am on Amazon looking for new bands for this watch and there are many options for replacement, even the exact factory replacements. The battery stays on High all the time and hasn’t gone to medium in the entire time I’ve owned it. The glass face is quite recessed in the resin bezel so it stays pretty protected and mine only has a few scratches.The only con that I can think of is the fact that when the watch is in the stop watch mode, which I use often for certain tests at work, The time is not displayed, and I always need to know what time it is at work. It’s a bit inconvenient to scroll back to the time setting, but that is a minor gripe.At this point I like the way the watch looks better than ever. It’s got a nice patina on it, and I don’t see it being retired at all within the next 5 years or more. I’ll quit wearing it when it quits.

    Perfection. If you’re looking for a simple G-Shock that’s easy to read day or night and doesn’t have a lot of features you’ll never use, this is the watch. The illumination feature actually works at night. The face is incredibly easy to read at all times. The size is perfect. I find many G-Shocks to be overly large and gaudy, but this watch is understated and will not draw attention. I gave up on models that have both analog and digital displays because the watch hands inevitably block the digital display throughout the day. If simplicity is your primary concern, do yourself a favor and switch to a strictly digital watch instead of compromising. I added a green nylon band from JaysAndKays which makes a world of difference in the appearance.

    This sits at a best bang-for-buck point on the G-Shock price curve. It’s a tough call between this and the GW-M5610. This has a better world time feature, but it’s bigger. You can dual-time it and scroll the world time in both directions. This has the “iconic” (some would say) three-eye design. That’s the main reason to pick this model, actually. The screen also has excellent contrast. I think it objectively looks more fashionable.If you were price sensitive enough to care that this is the best bang for buck, you are probably sensitive enough to go with the DW-6900 instead. The reason for this watch to exist is that it has the three-eye design with solar/multiband 6. If that’s what you want, you’ll like this.

    I don’t like how the third eye is pretty much pointless/useless. It’s nice that the left two eyes have some use now (compared to DW6900). Like many say, the display is nice and crisp, maybe even more so than the GWM5610 (although the 5610 has slightly larger font). I like that the days of the week are spelled in three large capital letters, instead of two small print lower case (on the GWM5610). Because of the dedicated light button (lower G), the upper right button will actually toggle in timekeeping mode between the current day-date and world time (the GWM5610 can’t do this, in fact, to access world time on the 5610, you have to press the mode button too many several times).This may not seem like a big deal, but the buttons are a lot easier to push than the GWM5610. The GW6900 displays current time in the alarm mode only, which is the only mode it makes sense to me to have the current time handy right away. Most importantly, the GW6900 doesn’t have a defective tilt sensor like the three GWM 5610’s I have ordered and returned through amazon – Press the 2,8 and 10 oclock button to engage the TLT (tilt) sensor test mode. Regardless of ambient light, you should see 88:88 with a slight tilt. Some say “Oh I don’t use auto EL so that doesn’t matter”, but actually it does in another way – you are supposed to be able to pick up and look at the watch and it should wake out of power saving mode automatically because the tilt sensor gets tripped – a defective gwm5610 won’t be able to do this.I actually prefer the case shape and size of the GWM5610, but there are too many defective units out there, so I went with GW6900 as my main driver.
