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.

I would think the Mudman since it is smaller, but big watches can look good on females too.

Unfortunately there is currently no GWG-1000 model with a positive LCD display. Perhaps that will change in the future.

Hi, is there any difference between GWG-1000-1A3DR and GWG-1000-1A3ER other than price? I’m working in India where the former is available for equivalent of £450, whereas it’s listed for £660 on the UK site. I’ve bought G-Shock in India in the past which did have a difference (didn’t have the multi band 6 feature), but I can’t see any immediate differences between these models other than ~£210!

It’s the same. The DR suffix means it’s meant for export outside Japan. The ER suffix means it’s meant for the European market. It is the same model.

What does mean an additional letters ‘ER’ in the type of watch, ex. GWG-1000-1AER?

It means that watch is designated to be sold in the European market. Otherwise it is the same as any other GWG-1000-1A model.

They are the same other than the colors. Some colors have limited production runs, or use ion plating on the metal parts for different color accents, so that will make it more expensive.

I need help.

I bought this Casio G-Shock MudMaster GWG 1000.

The LCD has a black background.

Is there any feature which can invert the colours of the display ?

I am used to the ProTrek which had a clear background with white digits.

Only thing that lets this tough G-Shock down is the light, my last Mudman illuminated the watch so well, you could read the digital screen. The GWG1000-1A3 has no lighting for the screen. I used to push the illuminated light button walk around the house using it as a torch it was that bright.

What is the best selling color. i have ordered a GWG1000-1A3 for about $450 and the other color are cheaper. The All Black model is the cheapest. I have read in one of the answers that few models are ion plated. Is the 1A3 model ion platted. PLease help.

Ahh I did a search but it didn’t show up. Oops! They’re all over eBay and judging by the prices not too popular.

Love my green GWG-1000 and would be lovely to see a new colour preferably with a positive led. All the best, Mark.

Hello. Why is the JF model more expensive in the markets then the 1A3 version? Is there something that makes the JF version more valuable? Also can you please tell me if the year they were made and the year they are sold make any difference? ie made in 2018 sold new in 2020. Thanks for the great information.
