Description

As an upgrade to it's predecessor, the new GWM530 add the ability to connect with the radio transmitter in China to update the watch's time & date in addition to adding an additional 18 cities added to the world time mode, for a total of 48-cities. The watch's time memo function has been replaced with a countdown timer. Black resin band digital watch with neutral face. CasioWith 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 perfect time piece
The best watches I've ever owned by far! This is my 3rd G Shock with the 3rd band on it now. The bands I'm very rough with. I've been wearing one every day since 1981. I wouldn't trade mine for any other brand. Rugged, waterproof, and will take blue collar, hard work and keep perfect time. This is my 2nd solar powered one and that's even better. It sets itself every night and I never need to worry that I have the exact time. You will not regret owning this watch! ... show more

Real G shock! Great watch
Was skeptical on spending more than $20 on a watch. I've always used cheap ones because they would get beat up when working. I finally decided to get something built to last. I looked at local stores like academy and the Mall. They had this watch for $130!!! I decided to check amazon and sure enough it was reasonably priced. The stores would not do price matching. I chose this watch due to the features it had: -Solar powered (never needs a battery) -Atomic time kept (exact time) -Digital (digital duh) -Black. (Dark chrome and flat black) I really liked this design, it's not extra large or huge like other G-Shock watches, This watch is a decent size. What I noticed right away was the clarity of the LCD display. It's clear compared to the other watches I've owned. It was easy to follow the instructions to change the watch settings. The neat feature is when you tilt you arm 40 degrees from being parallel to the ground, the indigo light automatically turns on. So far I've had it for a few days and seems to work great. This watch seems well built and meant to last. I would recommend this watch to anyone looking for a nice affordable G-shock that has neat features. ***update*** I’ve had this watch for 4 years and it’s still working great! It’s been through a lot or hard labor and outside elements. The band is still intact, buttons still work. Everything still works. This was a great deal! Awesome watch! ... show more

Excellent watch. This is my second same watch. First one lasted 21 years never replaced battery.

Great Watch at a Fair Price.
A very capable watch at a good price. The instruction manual is very small print, I recommend a you-tube video for instructions. Using the watch is very easy and once set up, you need not revisit it because it is atomic and solar powered. I would buy it again.

Review Image by David Alvarez
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. ... show more

Awesome watch. Casio fails with countdown timer.
I have always had Timex Ironmans my entire life. I never got a G-Shock because I didn't see much benefit over the Timex. but I am 99% in love with this watch after owning it for a few months now. The things that I love are: 1) Solar - every time I change the battery on my Timex it became less water resistant. this watch arrived with the battery indicator on high and it has not moved from there since I owned it. Even though I work about half the time on overnight shifts. 2) Atomic - No more wondering if you have the exact right time. The watch regularly sinks with the atomic clock almost every evening regardless of where I have it in my house. When around some the equipment I use it work it won't sync. But for the most part, it reliably does it's job. 3) All black - This model looks so much nicer in my opinion than the different variations of the same watch that have colored accents on them. It looks better for most occasions. 4) Large display - One of the major factors for me never considering a G-Shock was that the numbers on the display were always extremely small. I appreciated the large numbers on the Ironman. But this model has adequately sized numbers that are not difficult to see in any lighting condition. 5) Indiglo style backlight - I always loved the Timex backlight. It is bright and evenly lit so seeing the time in complete darkness is not an issue. All of the G-Shocks I ever looked at had some little dim backlight that shown from the side and did not illuminate the entire of watch face. That was a no go for me. This G-Shock has the same Indiglo style as the Timex. The only complaints I have about the G-Shock is that the timer function only allows you to set a minimum countdown time of one minute. There is a very specific task at my job that requires the countdown of 30 seconds. This watch simply does not allow you to set a timer for 30 seconds. It seems like that should be a relatively easy thing to incorporate into the module, but Casio for some reason has decided that no one needs to count down less than one minute. For that reason, I have given the watch four stars instead of five. All in all, I could not be happier with my purchase. I highly anticipate that this watch will be going strong many many years from now. ... show more

ABSOLUTELY A GREAT WATCH, SO GLAD I SAW A FRIENDS, NOW I OWN ONE!!!
A very good friend of mine had this watch and I asked him about it, and he told me all about it and how much he loved it. He is a techie and nerd just like me. We engineers and Ham radio operators always want the best gadgets and a good watch is one of them. Never need to set or change the time, easy to read, charges by sunlight, not a bad thing I can say! Everytime I now use and look at this watch, I say to myself and others.... I LOVE this watch! I like the total all black because the chrome trim one takes away from the display and it somewhat a distraction, the ALL black face watch as shown here is the one my friend had and the same one I got and I am very very happy with it. It also STAYS on your arm and does not slide around or move upside down on your arm. I love that and the plastic band is very comfy! So glad I found this watch. I now tell all my techie, nerd, engineer friends about this watch when I see them, Amazon had the best price too than any local store! ... show more

Rock solid build, menu system is complex but straightforward and powerful once you learn it. Worth spending time to get to know.
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 off 2) ALM - tells you if any of the 4 one-time alarms is currently on 3) 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 dark 5) 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 / off The 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. ... show more
