Casio G-Shock Mudmaster GWG-1000: All Models Released

Quick Jump: View all G-Shock Mudmaster GWG-1000 Models

Casio G-Shock GWG-1000 Mudmaster Watch

The highly anticipated GWG-1000 Mudmaster is now available for sale. This new model combines features of the Mudman and Rangeman with an analog/digital hybrid display. It has a case design that looks like a cross between an aviation G-Shock and the Rangeman, giving it a tough and tactical appearance. Model numbers are GWG-1000-1A (black), GWG-1000-1A3 (black with olive band), and GWG-1000-1A9 (black with yellow band). List price is $750.

The GWG-1000 is designed to withstand harsh environments like the desert or mud. It has a protected button structure like the Rangeman. In addition to mud resistance the watch is also resistant to heavy vibration. Like the Rangeman, the Mudmaster features the Triple Sensor with compass bearing, altimeter/barometer, and thermometer. It also has Tough Solar charging and Multi-Band 6 radio time synchronization along with the standard shock and water resistance (200 meters). Other specs include low temperature resistance to -10°C or 14°F, world time (29 cities, DST on/off), stopwatch (24 hours, modes: elapsed time, split time, 1st and 2nd place times), countdown timer (max 60 minutes), 5 daily alarms, hourly time signal, auto-calender, and dual LED backlights for the analog and digital displays. The watch measures 59.5 × 56.1 × 18.0 mm and weighs approximately 100 grams. Pictured is the GWG-1000-1A3.

The new Mudmaster is a tactical-looking watch that combines advanced technical features with extreme durability and takes the analog-style G-Shock to another level. Casio has been focusing on analog designs for its high-end G-Shock watches and it will be interesting to see how this trend continues in future models. The GWG-1000 will be getting a lot of attention as one of the premier G-Shock models and it is further proof of the brand’s ongoing commitment to high-end watches.

Kashif or whoever, Casio isn’t heading in the wrong direction. There’re G shock that cost less than $100.
This mudmaster is meant for those who requires a watch this tough, those who defend your ass when you’re sleeping.
Else, put it bluntly it’s meant for people who can afford it.

That’s ironic. You make a fair point about their being cheaper g-shocks, but as someone who has been waiting for a watch with this combination of features for a long time and does the defending you mention for a living I certainly can’t afford one. My previous Mudman gave nearly 8 years of faithful service before it literally fell apart and I would expect this one to last as well.

Is it unreasonable to wish that the digital parts illuminated along with the analog parts ? I know I can’t really see the digital with the analog light.

The Mudmaster actually has two LED lights, one for the analog display and one for the digital display. It is probably harder to see because it’s a reverse LCD display.

Thank you for all efforts to answer these many queries.

Please be kind and explain the meaning of Reverse LCD display.
Is it hard to read the time? On the same lines of Mudmaster, which watch is better with display and time reading?

Instead of dark digits, the background is dark and the digits are light. In bright light and looking at it straight on it is not a problem but in lower light and at angles a reverse LCD is more difficult to read. All the GWG-1000 models have a reverse LCD display.

magicjude – I ordered an extra yellow band for my mudmaster military green and it will cost me $115, it’s expensive for me but I ordered it anyway, since it will be available 60-90days from now I hope Casio can still reduced it’s price at least half so I can buy other colors available . This is a Great watch I used it everyday even at home , and the product pays for it’s price…

Got GWG in November in the green band. It’s awesome. I do construction work and I’m an outdoors type person so far it has held up good. I don’t believe I will mess it up on the construction site. Only complaint is that the rubberized plastic bezel has a matte black finish because of its size it rubs on the inside of my jacket sleeve. Now it is becoming shiny in spots that come in contact with long sleeve clothing. So basically the matte finish is getting a Polish from clothing.

Yes that is normal but you can set it so it doesn’t beep when you press the buttons. See section E-99 in the manual here. http://support.casio.com/en/manual/manualsearch.php?cid=009&MODULE=5463

Thank you. Actually what i mean is that this noise is like a creak, not the normal beep noise that all buttons do when you press them. in general i find the mode button looser compared to the other ones. This is what i wanted to know if it is normal.

Did this noise ever go away for you? I just received my Mudmaster and mine does the same thing. Mode button is just slightly more loose than the others… with a squeaky / creaky noise.

Hi All,
Other than the slightly higher cost and that it is for the japanese market, what does the Japanese distribution version GWG-1000-1AJF have over the GWG-1000-1A? Do both versions have saffire face and carbon fiber insert bands? Thanks

They are the same, but Mudmaster watches do not have carbon fiber insert bands. If the model number is the same before the JF or JR suffix then it has the same features.

Hi
I was talking to Casio trough facebook today and when i asked what the difference between buying an GWG 1000 in Sweden compared to buying a DR model was they said that a watched bought in Europe would intercept the signal from an antenna in Germany to calibrate time and that a Japanese model would only intercept the signal from japan cause of another radio frequency. So to my question, is this true? Will the DR watch intercept the signal or can i change the frequency on my own so it does? (i live in Sweden) And if it dont do I really need time calibration through radio transmitting? I would be happy if just the summer/winter time worked.
Please scroll down and read what i pasted from their website.
Best regards
Emil.

The following is copied from the specs of a GWG-1000 at G-shocks website.

Multi-Band Atomic Timekeeping (US, UK, Germany, Japan, China)
Receives time calibration radio signals which keep the displayed time accurate
Auto receive function (up to 6 times per day/up to 5 times per day for China)
Manual receive function
Signal: US WWVB, UK MSF, Germany DCF77, Japan JJY40/JJY60, China BPC
Frequency: US 60kHz, UK 60kHz, Germany 77.5kHz, Japan 40/60kHz, BPC 68.5kHz

And this is from Casio Europe/Swedens site.

Whether you are in Europe, North America and Japan or parts of Canada, Central America and China – once the watch has been set to the local time zone, it receives the relevant signal and shows the exact time. In many countries, it also sets summer and winter on their own.

With the Multi-Band 6 feature the watch can receive the signals from all six transmitters in the five different countries. It is not limited to only one transmitter or one country. Yes, just set the home city and it should work if you are within range of the transmitter. Keep in mind some parts of Sweden are not in range but Stockholm should be. The DR suffix just means the watch is designated for export outside Japan.

I don’t think so because the Mudmaster is more of a “land” model while the Frogman and Gulfmaster are the “sea” models, but I suppose it is possible…
