Description

From Casio G-Shock, the innovators of tough timekeeping, comes the GGB100 Master of G Mudmaster watch series that has been designed to endure the toughest environments. This watch features a carbon core guard structure case, in black with grey accents, that allows the internal mechanics of the watch to be protected from shock-induced damage. This watch is mud resistant with metal buttons that form a tight seal on the case, a dual back cover that consists of a stainless steel panel back and an outer cover made of shock resistant fine resin embedded with glass fibers, and the bezel has three layers of fine resin with carbon fiber inserts. The Quad Sensor capabilities provide instant access to a compass, altitude/barometer, thermometer, and an accelerometer that keeps track of your step count. Additionally, this watch connects via Bluetooth to a special G-Shock app that helps with the configuration, as well as records altitude data, route information, and step counts. These recordings are used to create an activity log you can use for tracking. Mode Switching Customization allows you to turn on and off individual modes and their sequence, for a personalized feel. This capable watch is finished with a olive green resin band.

  • An amazing piece of kit. Tech that's fun and useful, and t looks killer!
I own so many, too many watches. Most are three handed analog mechanical self-winding watches. But I have not abandoned digital. G-Shock is a range I cannot speak highly enough. Love love love their squares, but I had never been tempted by the well over 50mm+ sort like this MudMaster, and the like, until now. . Why did I wait, and deny a chance to enjoy these before? Kicking myself a bit, honestly. I have a 7.5" wrist, so their bulk is easily manageable for me. The features and ease of use on this one is very impressive, particularly with the phone app. No need to get into it all, go to YouTube for all the specifics. It rocks! Okay, no solar recharge. I saved a good $100 to not have that, and a new battery every few years is $2 As bulky as it is, the light weigh, fit, and comfort is better than most of my other watches. I happen to love its bad a$$ looks to boot. Go G! ... show more

Now that I have had this watch for some time now I figured I would do a little bit better of a review. This G-Shock is really a stunning watch. It definitely isn’t as big as the GWG-1000 it is lighter on the wrist and does sit more comfortably on the wrist as well. It comes with the carbon core guard that the GWG-1000 doesn’t but I believe the 2000 does have. This has a quad sensor which more G-Shocks need to have. You get the compass, altimeter, barometer/temperature, and step counter. The watch also has the Bluetooth connected app capability, which is fine but I could go without it. In its place I would prefer atomic timekeeping. This watch is nearly perfect in my honest opinion. If it had the multiband 6 and tough solar this watch would be pretty much unbeatable. I don’t need this to be a fitness watch so all the functions it has is all that’s really needed.. If Casio ended up adding the atomic and solar in the future I would buy one in each color way. The domed glass is nice but if I remember correctly it is just the standard mineral crystal which is still fine. I have banged this watch almost on a daily basis on this stupid doorknob in our hallway, and not a scratch, crack, dent, or anything. This watch has also been on it’s fair share of adventures and has survived with ease. This watch is just as rugged and durable and capable as the GWG-1000 and just about any other G-Shock. This watch is lightweight, durable full of functions that can help you out in the right circumstances. With the connected app you can track your steps do mission logs and whatnot. With the app you have close to full control over the watch. You can’t go wrong with a Mudmaster. ... show more

  • Good watch
Liking the watch a lot. Big and looks good. Negative display is bad as always but I use the analog and I always know what day and month it is.

  • Worth it
Great watch, as expected from G-Shock. Comfortable and beautiful watch. Worth every penny! If you don’t like big size watches then is not for you! If you are an outdoor person then this is the ideal watch. Thank you G-Shock!

  • Large, legible watch thats very comfortable to wear.
The watch is extremely comfortable and light on the wrist. The G SHOCK Connected App is very user friendly and easy to navigate. All the same functions can be performed on the watch itself and is simple enough especially when there are user friendly tutorials on You Tube such as Watch Geek and Henry Tech. Had the watch been solar powered it would have been a complete package but being battery operated certainly didn't deter the purchase. The barometer regulates the altimeter via air pressure so its a good idea to have an altimeter app on your phone in order to set your watch reading correctly before setting out on a hike etc.. for accuracy as the barometer alone fluctuates the elevation reading incorrectly. The mission log and location indicator features work perfectly and the illumination on the watch is substantial. Solid purchase. Being from Canada, I monitored both Amazon sites from the States and Canada and observed the fluctuating prices. The watch went down 30% on American site and was cheaper to buy with exchange rate and shipping charges included so be diligent. Watch usually sells for $425 Cdn but I managed to purchase it for approx $380 on American site after conversion. ... show more

  • Well built
Like the watch, but kind of boaring, face quite dark, not real impressive looking. Return was because I decided I want solar
