Product Description

The shock-resistant design of the Casio Men's G-Shock Atomic Tough Solar Watch makes it a one-of-a-kind timepiece. This tough watch is constructed with a durable black resin case, a stationary stainless steel bezel, and a black resin wristband with an adjustable buckle clasp for a personalized fit. A durable mineral window shields the digital-gray dial face, which features the time display, as well as the day, date, and month. The digital-quartz-powered watch includes adjust, mode, split/reset, and start/stop function buttons to fit your activity, as well as subdials that track battery life. It is water resistant to 660 feet.


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.

    Great for working out, outdoor use or just everyday wear.

    As long as you sit it in the window at nights per the manual it will set itself every day and accomodate seasonal time changes with no problem.
    My husband is in the military and has used this watch for almost two years and has worked well for him so we purchased one for our son.

    Having owned the GW500AJP-1AV for a week, here are my thoughts on some of the points raised by the reviewers of this and other G-Shock models:

    1. In my opinion, concerns about the thickness of the watch have been overstated. Certainly, if slimness is an *important* criterion for you, this isn't your watch. But you'll have no trouble fitting it under your shirt cuff. [Though the manual cautions that doing so will hamper the solar function.] Even my ridiculously slender wrists support it - physically and (I hope) esthetically - without difficulty.

    2. The G-Shock models are advertised as rugged. I'm not about to use mine as a hockey puck to put that to the test. But it certainly *feels* sturdy. [The thickness helps here.] And from what I've read about them elsewhere, they do shrug off a considerable amount of punishment.

    3. Everyone's experience with receiving the timekeeping signal from Fort Collins will vary depending on the particulars of their location and the attention they pay to the manual. I live only 350 miles from the transmitter but with modestly sized mountains in between - which can be a dealbreaker. Although it took a longer period of motionlessness for the watch to lock in than the manual had told me to allow, it has received a strong signal ever since. [And keep in mind that the watch is accurate to 15 seconds a month even without synchronization.]

    3. When I first unpacked the watch, the battery level was at Medium - which you would expect after it having been in a box for who knows how long. After 3 hours of direct exposure to bright sunlight [which you should do in the early morning to keep the watch from roasting], the battery level has remained High ever since.

    Verified Purchase
    I first bought a Casio G-Shock type watch back in about '82, a DW-1000, actually a precursor to the G-Shock. Still works great to this day, though I've replaced the battery twice and replaced the resin band with a metal one. This watch has served me well over the years from hiking to scuba diving. So I decided it was time to upgrade to the latest technology - a solar powered G-Shock with "atomic" timekeeping.

    This new watch performs great so far. It synchronizes to the Fort Collins signal every night without problems. I live roughly 700 miles from the transmitter. In the good old days I used to dial in the time signal on a shortwave radio to synchronize my watches. It's great to have a watch I can forget about setting.

    I was a little concerned before I bought this watch that Casio was relying on the time sync and the watch might not be accurate without it. This is important to me because I frequently travel internationally. Not a problem. My watch had last been synced about 6 weeks prior to my receiving it, and was off about 12 seconds. That's 2 seconds a week or less than 2 minutes a year.

    The other feature I especially like is the easy world time - a couple button presses and I can show time at whatever time zone I am in. Other functions like the stopwatch are easy to use without constantly referring to the manual.

    There are 3 round dials at top. The left acts like an analog minute hand. The center shows the battery charge, and the right shows if any secondary functions are active, like the alarms or stopwatch. The text on the right dial is almost impossible to read regardless of how young your eyes are.

    I think this watch looks great, but it is thick - almost 5/8 inch thick. So if you like svelte watches this isn't for you.

    First off, I agree that this watch can be found in retail stores for about that price or less and you can try it out while you are there. Once you own this watch, you can forget about needing to change a dead battery when you least expect it. This is due to the built-in solar panel. Also, it can update itself to the atomic time (USA) by using a signal that is automatically obtained by the watch early in the morning while you sleep. This watch has a tilt sensor that will automatically turn on the indiglo light when you go to look at it. I have had this watch for a few years now, and there is not a scratch on it. The band is still in perfect condition, but a little dirty. This is a watch that you can forget about replacing for many, many years.

    This is an excellent watch. It is virtually indestructible, feeds on sunlight, and "phones home." The common criticisms of this and its atomic G-Shock siblings are that they are cumbersome and ugly. Admittedly, it is not the slimmest, sleekest watch in the world. And no, it isn't the most elegant either. And clearly, style and comfort do indeed enter into the equation when you are shopping for a watch. But this is not a fashion watch, nor was it ever meant to be one. It is a functional one. You might wear a sleek, beautiful Movado watch to the opera, but you are not likely to subject such a watch to all the stresses and strains of an active lifestyle. This watch will take whatever you can throw at it and then some, and it will be accurate to the atomic second. So, it is a very different kind of watch from a stylish Movado. My Movado sits quietly in the darkness of my jewelry cabinet most of the time; it is "too good" to wear every day.

    I have worn my atomic G-Shock for over a year now, and have grown to depend on it. However, I recently decided to purchase another. Here's why: The watch does indeed feed on sunlight. You never need to hassle with a battery. You may have it fully charged in October. But as you go into the dark months of winter, without adequate exposure to sunlight, the watch will slowly begin losing its charge. Eventually, in the middle of winter, you may find it going into a state of hibernation if its charge falls below a certain threshold. In that event, all you can do is take it off and leave it in the feeble winter sunlight for a number of days until it is recharged. During that recharging time, you will need a backup watch to wear, if you have one. I didn't.
