Description

The Casio G-SHOCK MUDMASTER GG1000-1A5 is engineered for demanding environments where mud, dirt, debris, and impacts are part of the challenge. Part of the Master of G Land collection, this rugged analog-digital watch combines G-SHOCK toughness with Twin Sensor technology and a military-inspired design. Mud-resistant and shock-resistant construction helps protect the watch in harsh conditions, while its specialized button guard structure is designed to help prevent mud and fine debris from interfering with operation. Large Arabic numerals, broad hands, and Neobrite details provide excellent at-a- glance readability. Twin Sensor technology gives you quick access to a digital compass and thermometer. The compass measures direction from 0° to 359° and displays 16 directional points, while the thermometer measures temperatures from 14°F to 140°F (-10°C to 60°C). Dedicated oversized buttons provide intuitive access to these outdoor functions. The GG1000-1A5 also delivers 200-meter water resistance, world time across 31 time zones and 48 cities, a 1/100-second stopwatch, countdown timer, five daily alarms, and a Super Illuminator LED backlight with auto light functionality. With its rugged resin and stainless steel construction, textured resin band, and approximately two- year battery life, this MUDMASTER is built for serious outdoor use. ​CasioWith the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward. P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); This is the latest addition to the MASTER OF G MUDMASTER Series. Built to prevent intrusion by sand, mud or dust and to ensure reliable operation in the harshest environments, this tough structure is prepared to support training and actual missions in environments such as jungles and deserts. It's an ideal tool for rangers and rescue crews. Mud Resist construction helps to ensure that nothing gets into the watch when down and dirty work takes you deep into the dirt and sludge. Multiple gaskets are used on the pipes that guide buttons and shafts, which keeps mud out. These pipes not only act to protect buttons from impact, they also enhance button operation. See more

  • Watch perfect; seller not so much…
Received my new Mudmaster, and it is awesome. Huge, but awesome. The function, fit, and quality of this line of watches is great. I never thought I would buy a more expensive G-Shock as the others I own are great, but this one is steps ahead. The compass feature works, there are all of the world’s time zones, and it looks amazing. The ONLY downside, is the black digital display is a little hard to read. Now, the seller. The watch was Prime, scheduled to arrive in two days. Nine days later, my watch showed up. It wasn’t an issue with shipping, it didn’t get placed for shipment until later, so it was on the seller. The box it was shipped in was perfect, but the Casio box was heavily damaged, telling me that it was placed in the shipping box that way. The metal box the watch came in wasn’t damaged in any way, but it was a let down the actual Casio box was. There were also fingerprints on the back of the watch case, so the watch had been handled by someone before it arrived to me. Maybe it was a return, maybe not, I don’t know. All in all, I love the watch and it is my new go to for everyday wear. However, the seller could have done a much better job in getting me my new watch, in a like new box, in new condition. ... show more

  • This Watch Looks Better In Person
I had a feeling that this watch/bracelet color combination would be quite striking on the wrist. And it is! It is a very sizeable product (56.2mm dial) yet comes in at minimal weight. Oftentimes I even forget that I have it on. Several people have asked to have a closer look at it which I always take as a complement. The colors are striking and the whole system has a professional look about it. This is my first Casio and I picked a winner. But be prepared. The owner's instruction manual is very tiny and I needed a magnifying glass just to see all the detail. Setting up the time on this watch is not intuitive. While it should be simple it ended up being a quite complicated process. The myriad other functions available on this watch will just have to take a vacation since the time is all that's important to me. Please remember that the term "water resistance" means that you can not submerge the watch under water for any length of time. You will notice that the product page says "in general, suitable for professional marine activity and serious surface water sports, but not diving". The optimal words here are 'surface' and 'not diving'. If you're looking for an impressive time piece that will be able to take a lot of punishment, this could be your watch. Take it from me, it looks even better on your wrist. ... show more

  • Great Looking & Rugged - Many PROS and a few (Possible) CONS
I got this model because I was looking for a rugged Work Watch and for me it's hands down, the coolest looking G-Shock in their Line-Up. I hesitated buying it because of the dimensions (55mm) as I normally wear a 42mm and thought it might look ridiculously huge on my 7 1/2 inch wrists and would be knocking it all the time but for some reason, it doesn’t feel as gigantic as I thought it would. I’m often wearing long sleeve shirts and work gloves so maybe if you’re just wearing a short sleeve t-shirt it might look huge but it’s very comfortable and very light-weight and just plain looks cool. One of the main draws for me was the design, I absolutely love the color scheme and the negative display but be aware, as cool as it looks, the negative display isn’t always visible depending on the light you are in (see attached images)…but to be honest, I like that all of the displays are not front and center every time I look at the watch. I don’t need to see everything, all at once, all the time… it makes the display too busy for me.. In almost every circumstance, those displays have been readable so it hasn’t been an issue. Additionally, the windows that have the negative display contain Secondary Information… like the Day/Date/ 24 Hour Time/Compass/Temperature… so 95% of the time, I don’t need to see the Day and Date every time I look at the watch (though I almost always do see it) Once you know the day and date, you know for the rest of the day.. it’s not going to change…and if you like using the 24 Hour Clock, you already know how to calculate the time just looking at the analog hands, so you don’t need the display read out…same goes for the other read outs.. How often will you need to know your Compass Bearing in Degrees (the second hand points north so you don’t need the display) and the Temperature gauge only gives you an accurate reading when it’s off your wrist (your body heat affects the read out) so the fact that those windows might not always be visible, is a non-issue for me but if it will bug you, get one of the other models. For me the gray background on the positive display just reeks of “cheap digital” while the negative display is so much sleeker and this model also has the 5-Minute markers blacked out for added stealth… just plain cool I absolutely love this watch. In my opinion, the best looking G-Shock ever made. PROS: Great looking / Rugged / Light-weight / Comfortable / Easy-to-Read Analog Hands / Large Buttons for easy access / Cool Features (Alarms/Compass/Temperature Gauge/24Hr Clock/Countdown Time/Stopwatch/World Time/Dial Light) / PRICE-Originally released at $320 but got it for $200 Possible CONS: Negative display not always visible / Alarm Beep could be louder (I can’t aways hear it) / Temperature gauge only gives you an accurate reading when it’s off your wrist (your body heat affects the read out) / Being a combo Analog-Digital, the hands sometimes cover up the digital windows and obscure the Day/Date / Learning curve setting it up (wasn’t familiar with digital watches) but found a Youtube video that explained it all very easily Overall, I love this watch and give it Four Stars but can see where others might be put off by some of the possible Cons. ... show more
