Product Description

This Casio G-Shock watch is a highly accurate and durable digital timepiece perfect for travelers, adventurers, or anyone looking for a multi-function, rough-and-ready watch. Featuring atomic timekeeping, the watch automatically sets using radio signals to ensure perfect time accuracy. Charged by solar power, the battery can last up to eight months on a full charge without further exposure to light. The screen indicates the battery level, and the watch comes with a power saving function. Ideal for world travelers or international calls, the watch can be set for 29 time zones (30 cities), with or without daylight savings, and comes with a city code display so you know where you are. The watch also features four daily alarms and one snooze alarm, a countdown timer, a 1/100 second stopwatch, hourly time signals, and an automatic calendar pre-programmed through 2099. The octagonal bezel of dark gray resin gives the watch a distinctive look, and the octagonal digital display window offers an automatic EL backlight with afterglow for easy night reading. The rugged band and case are also made of resin. The watch is designed for enhanced shock resistance, is water resistant up to 660 feet (200 meters).


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.

    The DW5600 is a great watch, but I think this one is the better buy.
    The Dude
    The G-Shock Atomic Tough Solar GW5600J-1 is probably one of the best purchases I've ever made; or at least, one that has made me happy the most.

    The atomic and touch solar features are nice too, the watch syncs almost every night so I always have an accurate watch all the time.

    Way back in 1982, I bought one of the first Casio 5000 models. It was incredibly accurate, easy to use, had a countdown timer (which I used a lot) and seemed set to last for ever. In 1988 I crashed my motorcycle, and smashed the crystal on my watch. I threw it in a drawer, bought a new cheap casio (with less functions) and carried on. 3 years later I found the smashed one in the back of the drawer. It was still working and only wrong by 15 seconds! I've had various other watches since then, (really missed the countdown timer), but the Casio G-shocks were all way too thick to suit me. I really fancied the new Solar Powered and Atomic Clock synced Casios, but they were still too thick (and didn't have a countdown timer).
    Then I found the GW5600J. Based on the old 5000 series, Atomic, Solar Powered, 5 alarms and a countdown timer, full backlight. And the same style and thickness as my old 5000! Not thin, but not ridiculous either.
    I've had it a week now, I love it, I expect it to last the rest of my life (this sucker is tough), and neat, clear, easy to use and accurate!
    If you like digital watches (as opposed to analog), this is the one.

    This is a solid, well-built watch. Had I purchased it alone I would have loved it. The problem is that I had ordered two versions at the same time to decide which one I liked better. I got this one and the non-solar, non-atomic, 1987-tech DW-5600E at the same time to compare.

    Features the J has that the E doesn't have:

    Solar power
    Atomic time updates
    Multiple alarms & snooze alarm
    World time
    Auto backlight on when raising your wrist in the dark

    Features the E has that the J doesn't have:

    Day & date displayed simultaneously on main screen
    Countdown timer adjustable to seconds (instead of minutes as on the J model)
    Alarm can be set for a specific time, day or month, or any recurring combination of the two
    Smaller footprint for both wrist area and height
    Time is visible in all screens except alarm set

    The bottom line here is that the DW5600-E does the basic task of a timepiece better: it tells you the time, day, and date more easily and with less hassle than the newer model. There is no selecting the home city, putting your watch at a certain position in the window at night, worrying about charging up the battery, and all the techno-tasks related to a supposedly maintenance-free watch.

    The fidelity of setting seconds on the countdown timer is crucial for fitness use (a minute is forever when doing something physically challenging...), or photography (I still develop film and 15 seconds can mean overdevelopment...), or cooking, scientific experiments, etc.

    The 5600-E is lighter, smaller, and more comfortable to wear. The size difference may not seem like a lot on the spec sheet but the difference is tangible in practice.

    Multi-Band (US and Japan), Solar, G-Shock, World Time, and great retro looks makes this a great watch.

    I've been looking for an Atomic Solar watch for some time and it appears that everything in the market is just too fancy for me....many atomic solar watches are gigantic, others have compasses, barometers, thermometers etc and although those functionalities are great....

    sometimes, most of the time, during weekends - when going hiking etc -- many features needed in a great outdoors watch are unnecessary at the pool, mall, movies, bookstore etc.

    The 5600 has all the right features:

    1) solar (8month power reserve on one charge)
    2) atomic (two zones US and Japan)
    3) power saving mode
    4) back light (the good backlight that makes the whole display glow)
    5) world time (29 cities)
    6) easy setup of two time zones
    7) stopwatch
    8) countdown timer
    9) g-shock -- very tough
    10) waterproof to 200meters (good for scuba diving or the pool)
    11) replaceable band
    12) multiple alarms
    13) Auto sync with atomic or manual sync
    14) Manual time set (calenar to 2099--I'll be dead by then so that works I think)

    On the con side, this watch is a bit big but for some reason its not overpowering on the wrist even for midsize guys -- it looks like it belongs there....big but not huge and definitely not small.

    In its basic mode it tells:

    1) time (hours minutes seconds)
    2) day or month/date
    3) pm (or 12/24 hour time zone and whether you're in daylight savings time)
    4) how much battery you have
    5) whether it has signal from the atomic time sync

    Overall, I feel comfortable wearing this watch and don't feel like I'm wearing a supercomputer on my wrist.

    I really like this watch. It has all of the standard 'toughness' you expect from a Casio G-Shock: 200m Water Resistant, Shock Resist, tough plastic casing, quartz movement accuracy, stopwatch, alarm, backlight, etc. It is also a "Tough Solar" (solar powered watch- needs no battery changes), and a "WaveCepter" (syncs with atomic clocks for total accuracy). Please see the main watch page or other reviews for all of the watch features- they've already been listed here, so I'll just elaborate on my favorite features with this watch.

    Looks wise- It is another in the line of the classic G-Shock looking 5600 series (the two previous ones, the 5600C and 5600E are approved by NASA to fly on the Space Shuttle! This watch is probably too new for that rating yet.) In my opinion the 5600 series is the most subtle of all the G-Shocks. That is important for me since I wear this watch more than any other watch I own, and I want a tough watch that I won't damage being my normal active me, but I also want it to slide under my shirtsleeve if I'm at work so I won't look like 'office Rambo' with my superwatch!

    In my opinion, what really makes this watch great is that you can strap it on your wrist, and just forget about anything having to do with the watch except for having it tell you the info you bought it for. That means: Don't worry if you get caught in the rain or you want to go swimming- it's waterproof enough to scuba dive with. Don't worry if you have a very active or athletic lifestyle- it's shock proof. Don't worry about batteries- it's solar recharged. Don't worry about it being incorrect- it syncs itself to an atomic clock! It adjusts the month/day of year, Daylight Savings Time, you name it.
