Updated review

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. Read more

An amazing piece of kit. Tech that's fun and useful, and t looks killer!

Erik EwaldNovember 16, 2023

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! Read more

Light weight, feature packed ... hands down great buy!!! Zero regrets.

Ed B.June 6, 2025

BLUF: Great watch, worth every penny. While the watch is a BIG watch, make no mistake about that, it wears very well and is so light due to the carbon core, carbon fiber bezel, etc. that I really don't notice it at all. Not nearly as heavy as my Citizen E365 or EcoZilla dive watches ... love those too! At this price point, you won't find a more tech infused watch that really has all the functionality you need / want. Granted, you could step up to the MudMaster GWG-B1000 to add Solar and Multiband 6, but for me, it wasn't worth the additional $480.00, at least for now. Won't go into all the sensors that you know this has, but will say the Bluetooth connectivity with the Casio Watches App is a great feature. I'm starting to like that in my watches. Out of the G-Shock can, to my wrist, the watch was set up in a matter of minutes by simply pressing the connect button, quickly connecting the App, and since I already had my basic info in the App from my other BT Casio watches, I simply sent that info to the watch ... couldn't be any easier for such a tech infused watch. The durability, fit, and finish of this watch is exceptional! Not much else to say other than great bang for the buck! Fantastic add to my watch collection, don't think about it, just get it ... thank me later!! Very Highly Recommended!!! Read more
