The G9000-1V Mudman has an extra-protective case featuring mud and dust resistance. It’s a good choice if your deployment takes you to an extreme environment like the desert or jungle. The G9000 also has specialized features such as two stopwatches and five multi-function alarms that are more versatile than the usual daily alarm. The multi-function alarm can be set as a daily alarm, a date alarm for a time on a specific date, a 1-month alarm that sounds everyday on the month set, and a monthly alarm that sounds on a specific day every month. Although this particular model is more colorful with its red buttons than other G9000 models that are currently available, we suggest the G9000-1V for its easy-to-read non-inverted LCD display. Although the GW6900 display is more capable in some ways, some people may prefer the look and the straightforward layout of the GWM5610 display. The main digits on the GWM5610 are larger than the GW6900, making it easier to read.

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).

Model Comparison

The GWM5610-1 is more compact and slimmer (46.7 x 43.2 x 12.7 millimeters versus 53.2 x 50 x 17.7). It is better suited to those with smaller wrists and those wearing tight-fitting long sleeves. It is also a little lighter (51.7 grams versus 63). You can put it on your wrist and forget it’s there. 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.

CONS: No third analog hand for seconds (but does have a seconds display on LCD), countdown timer limited to 100 minutes The GW6900-1 has 31 time zones for world time, while the GWM5610-1 has 29, and both have 48 cities. The additional time zones on the GW6900 are UTC+5.75 for Kathmandu (KTM) in Nepal and UTC-2 for Fernando de Noronha (FEN) in Brazil, and the cities of Miami and Toronto are omitted (as they are the same time zone as New York). For the record, I am by no standards a "watch guy," and have never been. But recently, I have wanted a watch but wanted a watch that would be rugged yet also show the day, day/month, and time, along with a few timers and such, and this watch has ALL OF THAT and more! The three circular indicators on top are (from left to right) - amount of solar energy watch has (high, med, low), middle circle has the different timers, stopwatches, alarm settings, and the right circle is seconds by 2's (2 seconds, 4, seconds, 6 seconds, and so on to 10). All of these settings inside the circle itself will light up if they are "on," which is awesome as you can easily see if any alarms are on and how much solar energy your watch has. So right now as I look at my watch, the "high" setting is lit up so I know that my watch has a "high" charge of solar energy. I have one (of 5 possible) alarms on, so one of my alarm settings is lit up as well. At work, I put the 'mute' setting on, so that will light up as well if it is on. If any are off, they do not light up. 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.The Casio GW-6900-1 boasts an accuracy of ±15 seconds per month, ensuring that it keeps accurate time. Its tough construction and reliable mechanism make it a durable and long-lasting timepiece. 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 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. Features: World time (31 time zones, 48 cities + UTC, DST on/off, home/world time city swapping), 1/100-second stopwatch (23:59’59 max, elapsed time, split time, 1st-2nd place times, target time alarm, direct timing start button), countdown timer (60 minutes, settable in minutes), 5 daily alarms (with 1 snooze), hourly time signal, LED light with 1.5 or 3-second afterglow, full auto-calendar, button tone on/off, 12/24-hour format, hand shift 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.

I really get the love behind this model now after trying it out for a few days, but sadly cannot say I can raise this up to one of my favorites. This is the newer generation of the famous Frogman watch with its lopsided case, but with an all-analog display. It includes the latest tech and durability specs, as well as a unique feature that allows you to hide the hour hand under the minute hand to avoid confusion and allow you to only focus on the minutes, which are most important when diving. Features: Multi-Band 6 auto time adjustment, world time (31 time zones, 48 cities + UTC, DST on/off, home/world city time swap), 1/100-second stopwatch (60 minutes max, with split), countdown timer (100 minutes, settable in seconds), 5 daily alarms (with countdown), hourly time signal, full auto LED light with afterglow, full auto-calendar, button tone on/off, 12/24-hour format, hand shiftThe Casio GW-6900-1 is a watch with a Tough Solar mechanism, meaning it is powered by solar energy. The watch features an LCD dial, providing a clear and easy-to-read display. It is designed to be waterproof and can withstand a water-resistant pressure of up to 20 ATM, equivalent to a water-resistant depth of 200 meters.
