Description

This model possesses Tough Solar and Multi-band 6 Atomic Timekeeping technology housed within an even slim profile octagonal case. Non-Stop Tough Solar Power provides energy via a small solar panel combined with a large-capacity rechargeable battery that enables a variety of energy-hungry functions to operate smoothly. Black resin band digital watch with neutral face. With 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.

Customer Reviews 4.8 out of 5 stars

abunda_amazon_reviews The direct descendent of the original Casio G-Shock that was released in 1983 is the GW-5000, which is available as an import from Japan. This GW-M5610 is a first cousin of that pricier watch and it carries on the tradition of tough square G-Shocks. What you lose from the GW-5000 is the stainless steel case with a screwed-down back whereas the GW-M5610 has a resin case with a stainless steel back plate held down with four screws. Both watches have identical features including solar charging, atomic time synchronization, World Time, four daily alarms with snooze function, a countdown timer, a stopwatch, and electroluminescent illumination that can be automatically engaged with the movement of your wrist in a dark environment. The GW-M5610 gets a red surround and white, blue, and yellow writing on the face which makes it a little busier aesthetically than more monochromatic versions of the 5000 and 5600 series. The first thing I noticed about the watch is how much smaller, thinner, and lighter it is compared to round G-Shock versions I own. It is an excellent choice to wear under long sleeves and jackets because it easily fits underneath them with minimal interference. I will be using this watch in the winter months for daily wear due to its sleek profile. The second thing of note is the crisp clarity of the numbers in the positive LCD screen. It surpasses my Casio Pro-Trek PRW-3500 in regards to off-axis legibility even though the Pro-Trek’s digits are 50% larger than the GW-M5610’s. I am really impressed with how good this watch’s display is. I find the strap fits comfortably on my 7-1/2 inch wrist. The light weight makes me forget that I am even wearing a watch at all. Contrary to the dozens of complaints from previous owners here on Amazon, my auto backlight function works perfectly fine even though I leave it shut off in order to conserve power. My watch was manufactured on January 8, 2015 so maybe Casio has finally fixed the issue with faulty backlight switches. There are several one star reviews of this watch here because of this issue and I honestly cannot understand how one can downgrade the rating of the entire watch due to one feature that most G-Shock users end up turning off anyway. The auto backlight duration unfortunately is not adjustable like my Pro-Trek and Gulfmaster. I would prefer the ability to lengthen it from 1 second to 3, but this is a minor nit. The function buttons are all recessed into a protective niche on the side of the case so pressing them only works for me when I use the tip of a fingernail. Action is positive and appropriate for the pressing force I apply. The World Time, stop watch, and timer functions all work like other Casio digital watches and are intuitively accessed with mode button. The one complaint I do have is that the volume of the alarm signal is very weak and probably would not wake a person from a deep sleep. If Amazon’s star rating system would allow it, I would subtract a half star for this and would suggest not relying on this watch for important wake-ups and instead using the alarm from dedicated alarm clock or smart phone. Note that this isn’t any different than the other Casio solar-charged watches, so it may be a function of reduced battery capacity. My watch arrived from Amazon with the power reserve showing at the Medium level. I put it out in the sun for about 30 minutes and the reading went to High. I set my home city, clicked Daylight Savings Time to the automatic setting, and synched the watch to the atomic clock signal in Ft. Collins without any trouble. Each evening just after midnight it synchs automatically so the watch always has an accurate time reading. I’ve had no issues with not receiving the signal but then again I live in a state bordering Colorado and all my atomic watches synch each day without fail. This watch is a great heir to the spirit of the original G-Shock. It wears small and comfortably on the wrist, is tough as nails, cost about one-third of what the GW-5000 does, has the accuracy of atomic synching, should run for a decade or more on the original solar battery (note that all solar watches will need to have the rechargeable battery replaced as some time in their lives), and has a very clear and legible display. As a long-time G-Shock owner, I have previously been drawn to only the round case models. I find it remarkable that after finally taking the plunge with this square case GW-M5610 that I have been absolutely delighted by this watch. It’s certainly not very flashy and has a nerdy charm of its own. No one in going to compliment you on it, but that’s all part of the fun of being a G-Shock fan. I now regret taking so long to come around to the Square Side and can recommend this watch most highly.;;Reviewed in the United States on February 1, 2016;;5.0 out of 5 stars;;A great heir to the original G-Shock, updated with solar-charging and atomic synch;;Lee K;;;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.;;Reviewed in the United States on August 17, 2017;;5.0 out of 5 stars;;Versatile watch, perfect for everyday use;;D.
