    • Mudmaster complete.

Absolutely beautiful watch. I’ve wanted one of these for years. It said 54mm and I expected to be bigger than my other mudmaster. It wasn’t. However, seems more secure or solid if that makes sense.

    • I've bought 5 watches from seller. All A+++
Love the quality, appear to be legitimate of course. A bit spendy but I've bought 4 Casios from this seller and they've all been brand new original and appear to be real not fakes or anything weird. Love this one the most which was also the most money but I've finished my Casio Pro Trek etc. collection. Lol. No more spending from me but a happy camper. I'm a watch guy and this was my 29th watch and 12th high end Casio. Gorgeous!!!! My favorite of them all ... show more

    • The ultimate Tool Watch
This has great durability, runs on solar, a full suite of sensors, it's easy to read and sets time based on radio signals. It requires no connection to a phone for any of it's functionality and doesn't rely on bluetooth. I have numerous G-Shocks and I think this is the overall best of the bunch.

    • G-SHOCK names says it all.
I bought my first G-Shock ever back 4-5 years ago, the Mudmaster GG1000 and loved it lol abused it with water, oil, dust etc and it with stood all that tortured, I expect the GWG 2000 to do that, plus more. First major selling point for me was the fact that it's Solar powered which is great for obvious reason. Watch arrived from Japan in a really nice black box with the words " G-SHOCK in silver color and all the booklet and instructions in Japanese. Watch looks really beautiful in person lol pictures and youtube videos do no justice, really comfortable watch. Will not go into details about the watch ( Youtube it) but over all, you can not go wrong with a G-SHOCK. ... show more

Received a copy of this watch with an issue, the mode dial was out of alignment, when I contacted the vendor ONE.MORE they promptly took care of my issue and sent me a new copy out right away, excellent service from them and would wholly recommend them.

    • Great watch
Great watch. Unfortunately, not user friendly for those that are farsighted. That said, I still like it and sits as part of my collection.

    • Well built, nice feel, tough it's a G-shock just like it should be.
The media could not be loaded. I already wrote a review on this G-Shock, I am not sure what happened to that one but it's nice enough to write another. I go way back with G-Shocks, I have been wearing the GWG-1000 for many years and put it through countless ops. That watch is still here and still running strong. When I got the opportunity to upgrade to the GWG-2000 I wasn't sure. I am really glad I did, the new one feels fantastic and I love the double positive display, the carbon fiber replaceable bezel and of course all the other tech in this G-Shock. If it performs as well as it's predecessor, I definitely made the right choice. ... show more
