Casio Men's G-Shock GW6900-1 Tough Solar Sport Watch

Product Information

Atomic syncing works brilliantly for me in Edinburgh. Solar power less so, as we rarely get to see the sun....

The third circular graph is mostly eye candy, divided into ten segments which turn on / off sequentially as an ersatz second-hand during the default time mode, making a 360-degree “sweep” every ten seconds. In stopwatch mode, the pie graph segments represent 1/10th of a second and cycle on and off accordingly, making a 360-degree sweep every second. Unfortunately, it doesn't have a time swap function where it swaps between the home time and the second time zone.Plenty. It has Multiband 6 so it receives all the time signals in each country that has such a service. It is also solar powered and basically won't need a battery. There is a rechargeable battery in there and that should be good for 20+ years unless you put the watch in a box. Even if you have it just laying on a desk it will be good for a very, very long time. The lower rectangular LCD area displays the usual time, day / date, and other chronograph functions. One unique function: the ability to toggle the day / date display with the World Time (city / time zone of your choice). The DW5600 and DW6900 do not have world time, so there are no differences between the two models in that area. Other limitations are only one alarm, no option to turn the button operation sound off, and no adjustable afterglow duration on either model. (It should be noted that the alarm is a “multi-function alarm” and not just a “daily alarm,” which offers a daily, date, 1-month, or monthly alarm.) The dimensions and weight are slightly different from their GW counterparts at 48.9 x 42.8 x 13.4 mm and 53 grams for the DW5600 and 53.2 x 50 x 16.3 mm and 67 grams for the DW6900, though not enough to be very noticeable. The GW6900 has a front light button that is easier to access and press than the side light button on the GWM5610. Many people also find that the side buttons on the GW6900 are easier to press than the buttons of the GWM5610. The watch on the left is a GW-9000, not a G-9000MS, but it uses the same case, bezel, and strap, so they're identical in size and shape.

Mine arrived today and it's a really great watch. As Till has covered the bases, I'll just add my particular pluses and minuses, particularly in comparison with my GW-M5600-1ER. Just for reference mine is a GW-6900-1ER. In their favor, the DW5600 and DW6900 have “flash alerts” with a flashing display and buzzer for the alarm and hourly time signals. Also, the countdown timer is settable in 1-second, 1-minute, and 1-hour increments, rather than just 1-minute and 1-hour increments for the GW models. The timer also has an auto-repeat function. Although bigger that the GW-M5600 it still sits well on the wrist and is if anything more comfortable.

Model Comparison

I can see little point to the functionality of right hand eye which merely marks passing seconds. I suppose it balances the appearance of the display. The one in the middle is NOT a DW-6900, it's a DW-6 600. It's a different module inside, but they use the same case, bezel, and strap -- which makes plenty of people happy when they restore their 6600 and find those parts are discontinued -- and they're also identical in size and shape.

The alarm seems louder than the GW-M5600, possibly because of the larger case. It's still not loud enough to wake me up! The GW-6900 on the right is mounted on Casio strap adapters and a one-piece Zulu strap, which may affect the way it compares to the other two models while strapped to a piece of wrist-sized PVC pipe (and no, it's not "wrist-shaped" which means the third shot does not accurately reflect the "wrist gap" on any of them.)

Comparing Products

Since the G-9000MS is NOT commonly sold in stores it brings up another large issue: have you read the many threads around here about "negative visibility?" https://www.google.com/search?q=sit...rums.watchuseek.com/f17+negative+hard+to+read The Triple Sensor is not a professional-level instrument. If your life depends on a good compass, get a good compass. Same for the altimeter. Due to body heat, the thermometer is only accurate off your wrist. The Rangeman buttons are large, with a cross-cut texture. They’re easy to find and press, even with gloves. That’s because the Rangeman 9400 is a BIG watch (55.2 x 53.5 x 18.2-mm). It’s also a BOLD watch. One of the Rangeman’s unique features: one-touch instant start for the stopwatch. If you’re in the normal Time Mode, a single press of the lower right button will instantly switch modes and start the stopwatch. You can also get to Stopwatch Mode by cycling the lower left mode button.

The timer and stopwatch modes can be set to 24 hours, rather than the stingy hour long versions on the GW-M5600. The 6900’s easily recognized by its round shape flattened at the bottom, the “three eyes” (a.k.a., “triple graph”) and the light activation button located front and center on the bottom of the face.I agree that the GWM is superior overall. But the GW wins on price and I also think it wins on looks unless you really want the watch to be as small as it gets. Of those three models, the G-9000 is probably "wears" the smallest. As Watch_Geekmaster noted, the straps on the DW- and GW-6900 "gap" at the sides of the wrist for a lot of people. Even though it's a different model, there's a great picture of the problem in this thread: https://www.watchuseek.com/f43/skinny-wrist-strap-mod-less-strap-gap-more-flex-676089.html One of the key features of this watch is its solar power mechanism, which means it is powered by natural sunlight rather than a battery. This makes it a sustainable option for those who are eco-conscious. The watch also includes a calendar function, which lets you stay on top of important dates and events. Being able to scroll east and west in world time is great, as is the ability to press B in timekeeping and see your last viewed world time above your time. With the press of a button you have a GMT watch. The Triple Sensor works well as a general reference. The barometer is the most useful of the functions; it includes a barometric pressure trend graph. The trend graph can be toggled on to replace the weekday at the top of the LCD (displaying constantly in the Time Mode).
