    Reasonable Doubt

    The G-shock line is absolutely amazing. However, I have to point out that the metallic grey color on this model is significantly darker than shown in the advertised image. It is dark charcoal, approaching black. Under most lighting conditions, it looks black. I have several G-shocks already and know their great quality, so I chose this watch for its color scheme. I was quite taken back with such a huge difference between the advertised photo and the actual unit I received. Also, the background is very orange. Compared to the version with grey background, it offers much less contrast and it hard to discern digits under certain angles. I am not very fond of this particular feature. The back light is greenish, like on most G-shocks.The watch arrived with low battery, but it took only a few hours under a light source to reach the medium level. It has not been able to receive updates yet, despite being beside a window all day. Hopefully, it will over the next few days.

    I bought this Casio GWM530A-1 to replace an old Timex Ironman. This review is based on my first few days of use.GENERAL: this model uses the Casio 3405 module, which it shares with other G-Shock models. English instructions came with my watch, others have said they needed to download the English instructions, which you can find here: […]Key features are solar charging, atomic clock sync, G-Shock build, and 200M/20Bar water resistance (good enough for professional marine activity, surface water sports; not good enough to dive with). This is NOT ISO 6425 certified as a “dive” watch. Some reviews suggest this is not as waterproof as the marketing suggests. To be safe, consider not pressing buttons underwater.BUILD: solid – built like a tank. It has more heft than the Ironman. My Ironman had a 38mm diameter case, the GWM530A is about 46mm. As G-Shock watches go, this is actually on the smaller side (I looked at another model that had multiband WaveCeptor / Tough Solar and it was a whopping 53mm). This watch is about a centimeter thick – don’t expect to slide this under fitted dress-shirt cuffs. This is the largest watch I own, and probably the largest I can pull off without looking ridiculous. For comparison, my daily dress watch is a 42mm automatic on a NATO strap. The case is chunky, dense. I like the aesthetic and the three mini-indicator circles. Not quite as retro as some of the other G-Shock watches. The indicators are, from left to right, a seconds counter, a solar charge indicator, and a multi-purpose indicator with six segments:1) SIG – tells you if the hourly time signal is on or off2) ALM – tells you if any of the 4 one-time alarms is currently on3) SNZ – tells you if the 5th “snooze” alarm is on (an alarm that can be suppressed for 5 minutes at a time)4) AutoEL – feature to automatically illuminate the face when you tilt the watch face to 40 degrees from level to view it in the dark5) MUTE – tells you if button press “mute” is on – when off, there’s a chirp when you switch modes (bottom left button).6) DST – tells you if daylight savings time is on / offThe strap is dense, premolded (the watch won’t lie flat on a table) and appears to have strong mounts/screws to the lugs. Two slightly-recessed buttons per side that sit just below the edge of the case. I really like that they’re recessed by about 1mm – it avoids accidental button-presses, which was a problem I had with my Timex whenever I extended my wrist.FEATURES:ToughSolar – the watch arrived partially charged. Needs a day in bright sunlight to get to “high”, but once there will typically keep the charge. It will charge in cloudy light / incandescent / fluorescent bulb light, but more slowly. Charge can be assessed at a glance by looking at the middle circular indicator, which is divided into 3 zones (high, med, low). The watch has a power saving mode that you can turn on/off. In PS mode, the display will turn off when it’s dark and the radio for atomic clock syncing will also turn off. I keep PS turned on, but it’s never kicked in since my charge has never fallen below “medium”.WaveCeptor – Casio’s name for atomic clock time syncing. There are 6 atomic clock signals across the world that this will sync with. These clocks are accurate to within 1 second every million years. So, you know, probably good enough for whatever you’re doing. The one for US / North America is in Fort Collins, Colorado. There’s one in China, two in Japan, one in Germany, one in the UK. As long as you’re within 1500km (about 900 miles) from the European or Asian clocks, or within 3000km (about 1900 miles) from the US clock, it should sync. I am in the mid-atlantic / Delaware Valley on the east cost of the US, and it will sync fine when I put the watch by the window overnight. The watch shows the strength of the signal (L1 = weak, L2 = med, L3 = strong). I get L3 if I position it just right. You can either set the time manually or have it automatically fetch from the atomic clock. You can also manually fetch the atomic time (like, when you first get the watch). It will automatically poll the atomic clock up to 5 times at night, until its successful. The scheduled times for N. America are between 12am and 5am. Lots of reviews indicate people have issues with syncing, but Casio is very clear about why syncing works better in some circumstances than others. All I can recommend is that, if you’re having trouble, you systematically go through the steps in the manual.EL and AutoEL – the “G” button at the bottom of the face turns on the electroluminescent backlight for either 1 or 3 seconds (you choose the duration). In addition, there’s an autoEL mode where, when it’s dark, the gesture of moving the watch face from level to tilted by 40 degrees (basically, the gesture of tilting your wrist to see the face) will turn on the backlight. This is a very intuitive and useful feature!Timekeeping Mode – it’s a watch with AM/PM, h/m/s, month, date, and day indicator. Because of the atomic clock function, it automatically deals with leap year as well as daylight savings time (which you can also manually override). First step when you get the watch is to specify your home time zone. Also recall that the time syncs to atomic clocks between midnight and 5am. That means if the set time is way off when you get the watch, it won’t sync (it will poll the atomic clock at the wrong times of day, when signal is weakest). That means you may have to manually set the time when you first get the watch, just to get it to poll the atomic clock correctly. Pressing the bottom right button toggles between either showing the date/day or a secondary time zone (world time) at the bottom of the display. Left circular indicator is a seconds indicator with 10 segments. The circle counts up 10 seconds then counts down 10 seconds. So it’s a relatively easy way to visually divide a minute in multiples of 10 or 20 seconds. That being said, I don’t use this indicator much.World Time Mode – great feature. With one button press, you can switch to world time mode. The right 2 buttons move you from timezone to timezone. Up is westward, down is eastward. You can also manually set/override daylight savings time in world time mode.Alarm Mode – individually set up to 5 alarms per day: four one-time alarms, and one “snooze” alarm. The alarm isn’t super loud – don’t count on this to wake you from a deep sleep.Stopwatch mode – standard stopwatch with start, stop, split, restart, and clear.Timer / Countdown – set a countdown timer in hours/ minutes up to 24hrs. You can’t set a timer for less than a minute, in case that’s an important feature you need.SUMMARY:This is my first G-Shock. I got this for less than $90, about twice what I paid for my Timex Ironman. But it’s an amazing value – you never have to change the battery (eventually, you might have to replace the rechargeable battery), you never have to set the time/date/DST, you don’t even have to press a button to view the time in the dark. Very high quality build and feels more solid/hefty than the Ironman. I think it’s at the sweet spot for size at 46mm diameter – totally useable as a daily beater, not too flashy, looks dressy enough for work. If you’re looking for a full-featured, shockproof, waterproof watch with solar charging / atomic syncing, consider this one.

    I bought this G-shock after I broke my other one while trying to change the battery. What sucks is I didn’t even buy the right battery! Anyways, screw battery changing. That’s why I bought this solar-powered version. I also love atomic watches, and all of my Casio’s have been on point with my computer time. This one always seems to get a pretty good signal, too, unlike the last one I had. It was even able to get a signal in the prison I used to work at. That being said, I’ve had this watch a few years now, and it’s been through my correctional officer days, all through nursing school, and now as a RN. I’m not sure I could recommend a better watch for the price. It’s probably even better than my $400 Seiko. $90 may seem like a lot for a watch for many people (I think I got it for $60 here on Amazon), but I have put this watch through a beating and have never had anything that has held up like this has.

    I have had several of the G-Shock Solar Atomic watches, and I have never had to replace one due to breakage or failure. The last one was 7 years old…and I lost it. Lol. This one is the replacement.I work in the oil field on a drilling rig. These can take a serious amount of abuse. Mud, dirt, impact, water, and even chemical exposure. When it gets dirtied up, brush with a fingernail brush to get the stuck stuff out, then throw it in the washer with your clothes. (no dryer. lol) Epic build, and every tool you commonly need. Easy to change time zones for travel back and forth, and I travel a lot.The watch face is just the right size. Not too big, and not too small. It’s a comfortable forget-you-have-it-on toolAbsolutely wonderful watch. I am a loyalist for life due to the durability, style and function. Just Awesome.

    As a full time Firefighter / EMT, I needed something extremely durable and waterproof, and wasn’t too large to go under fire turnout gear and still get a proper fit. It’s exactly the same size as my old Ironman watch. (I added a photo for comparison). With the solar and atomic sync, I don’t have to worry about adjusting the time or changing batteries. I really don’t use the other features except maybe the stopwatch or countdown timer, but they’re there if I need them. The buttons are a little small for my fat fingers, but still functional. The display dials are also kind of hard to read, but I had to compromise because I was looking for a smaller watch size than many of the other G-shocks. I wish the back light stayed on longer and was a little brighter, but it’s adequate. Overall it’s a great watch, and excellent for well under a hundred bucks. I’ve been wearing inexpensive Ironman watches forever. They took the abuse I dished out, but the straps and buttons always ending up breaking or the battery fades out, and I have to replace it every few years. This is my first G-Shock, and is definitely a step up.

    I’ve had this watch going on 2 yrs. When I got it, the battery was low and the clock was not set for my time zone. At first I was worried because I couldn’t get it to atomic set. Was dead of winter in CT. After 9 days, it suddenly set itself in the middle of the night. I kept it in the sun as much as possible for the gray New England winter. Within 2 weeks it was fully charged and on correct time. It’s waterproof features are awesome. It’s tough, and has been banged up several times. Very slight damage to the face from work. I work on the railroad in all elements, and never not dirty. I’m completely satisfied with this watch. It’s still on full charge and has never gone down so far. I set the atomic clock to program it once a week or so, just to keep as accurate as necessary. There are times that it doesn’t set itself. That’s atmospheric. It’s definitely worth the money for me. At first I also felt it was a bit small. And it is. It’s not a huge face, but it’s just right for me. The resin band is tough but comfortable. This is the BEST watch I’ve ever had. In forms of toughness, capabilities, charge hold, accuracy, size, band…. This watch has been in the toughest situations.

    This is the best watch I’ve ever owned. I wear it with dress clothes (business casual obviously) and it looks fine with it. If you’re looking for a great watch that is ALWAYS on time, go with this one. Every night at midnight the watch receives it’s signal from Colorado. If it can’t receive it at midnight, it will try again at 0100, then 0200, then 0300, so on and so forth until it gets it. The digital display is clear and easy to read, and as a pilot it’s useful for me to easily view the Zulu – or UTC for you ground-pounders – time. Just hit the top right “reverse” button and it’ll appear where the date usually is. Really great for copying down when you’re taking off or landing (if you’re a pilot)- if not it’s still helpful to view other time zones.GET. THIS. WATCH!! You’ll be very happy.

    My 6th G-Shock, which I’ve been wearing for many years. This is unquestionably the best so far (though I do have a Rangeman on order, due to arrive next week, that could take the lead). The Atomic Timekeeping function is sweet, it will keep your watch accurate literally to the second. I just prop on the windowsill at night while I sleep, and it synchs with the satellite in my area. Also love the solar battery, my 2nd solar Casio watch. Tired of changing batteries, which generally breaks the waterproof seal (have wrecked a few watches that way). Just be sure to keep it exposed to light as often as possible (indoor lighting will work, but direct sunlight better). Automatically powers off at night, display goes blank until exposed to light. Great energy saver. Easy to program, it came with a manual (tiny print) that explained everything thoroughly. Band is very comfortable for my medium sized wrists. Numbers are easy to read, larger than my other Casio watches, good background contrast. The alarm is very soft, if you need this to wake you in the morning, you will be late for work 🙂 Other than that, perfect. Love this watch!

    I’ve been rocking a classic DW5600E-1V since 2008. I have changed the battery 3-4 times and it has been nothing short of a perfect and comfortable time-keeping device. I went swimming though and it took on water – not just fogging. So the hunt began. I could have just gotten the tough solar version of the 5600 but I was open to trying something new. I wanted solar, a little easier/practical to navigate, larger than average (for Casio) numbers, and multi-band sync.This checked all those boxes and also had easy to set dual/world time, not to mention you can navigate forward and back (unlike the module in the 5600). Yes, the subdials are mostly for show but you really don’t need to know what’s on them to operate and set up the watch as you like. I have to admit this looked a little weird – maybe not as much as many over the top G’s – but still less conservative than what I was used to. I really do wonder what person or team designed this watch. It has lines that have really grown on me but how did this come into production?I decided to go for it – the large numbers was the biggest initial factor. After wearing it for a couple weeks though I have to say it is hands-down the most comfortable and balanced watch I’ve had on my wrist. It doesn’t rotate, is very light – even as it’s a bit thicker than my previous G. It also has a very comfortable proprietary band that is of moderate length and a slick keeper that you don’t have to readjust all day. I’ve been from New England to Virginia and it’s been 100% reliable syncing time automatically overnight or manually. Just go through the manual slowly if you have questions (or download it from Casio support) and you’ll get to know the features pretty easily. I’ll be wearing this until it dies – hopefully another 10+ years.

    I had a previous edition of this watch for twelve years and bought this one to replace it when the solar battery finally began to die. It is a nice compromise between the bulkier G-Shocks (I own several of these) and the smaller profile 5600 series. The atomic time synched works very well on mine; I wear it to bed and it syncs overnight. It also syncs when in the watch case. I live in SW FL and summer in the Boston area. And it received the signal most nights. It is extremely accurate without the syncing and, if you need it, there is a two dollar app you can get for use in tough reception locales. Mine arrived fully charged and has never dropped below high. While not a fashion statement, this model give you everything the best G Shocks have and at an extremely affordable price. The band is vey high quality and comfortable. The little round dials are impossible to read but seldom needed. Stop watch, timer, world clock—these are all intuitive for the seasoned G-Shock owner, but you can always download the manual from the G-Shock site and toss the hard to read add booklet. Even though I own ten other G-Shocks, I keep coming back to this old favorite for daily (and nightly) use. The backlight is very bright and the automatic illumination feature is handy when waking up at night for those trips to the bathroom. There are several versions of this model, and they all look great. Get one and you’ll be glad no matter how many fancier watches you own.
