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 119 grams. Pictured is the GWG-1000-1A3.

The new Mudmaster is a tactical-style 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 lately, 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 premium G-Shock models.

UPDATE: The retail price for the GWG-1000 is $750. Recently discovered leaked model numbers also show a listing for a GWG-1000GB-1A “Master of G Black and Gold” seasonal December 2015 release for $800.

UPDATE (August 24): Casio America announced the release of the Mudmaster GWG1000-1A3 and GWG1000-1A9 and stated the Mudmaster is part of the Master of G line.

Usability Update: The Mudmaster GWG-1000 has proven to be very popular, especially with customers in the United States and Europe who are looking for a very large and rugged outdoor watch.

GWG-1000 Pros: Triple Sensor for outdoor activities. The electronic crown allows for quick and easy setting adjustments. Very rugged style with mud and dust resistance. Ideal for large wrists.

GWG-1000 Cons: May be too large for smaller wrists. No sunrise and sunset time like the Rangeman GW-9400. Only available with inverted LCD display, which can be more difficult to read.

Alternatives: The battery-powered Mudmaster GG-B100 is smaller with a Triple Sensor plus a step counter and Bluetooth smartphone connectivity. The Rangeman GW-9400 offers similar functions with an all-digital display. The GBD-H1000 also has a Triple Sensor and solar charging plus a step tracker, heart rate monitor, and GPS timekeeping. There are also many Pro Trek watches with Tough Solar and the Triple Sensor.

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.
I wanted to buy Mudmaster GWG1000-1A3.
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.

Yes, it will be the same. G-Shock functions, menus, and LCD displays are always shown in English only. If you need the instruction manual in English you can download it here.

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…
