Love this watch. G shock is the greatest watch for work. I don’t have to worry about snacking it off things and it looks great. Well worth the money.

My favorite watch.
Edit - 9/25/25 - it's $245 now. I paid more for my All Black Rangeman. Now almost $60 cheaper then what I paid. EDIT - this is listed for $258 right now. If you’ve been waiting - ive never seen it that low. I bought this to splurge on something for myself, and I’m really happy with it. My favorite G shock and ive been looking at mudmasters for a while now. It does a whole bunch of things that ill never use, but having the app to change alarms and settings on the watch by using your phone is much easier then not having it.. The step counter is also kinda fun. Its not very heavy either which is really nice. The solid construction and quality of build is very obvious. I like the orange band which i wasnt sure i would. Most of my other watches are all black and the orange color adds some nice detail and makes it stand out. I was originally planning on buying an all black model, but I’m glad i didnt. Ive added a screen protector to mine, which you might notice in the pictures. Yours will not come with that. I work a labor job and I’m not planning on beating the hell out of it, so i do take it off if i know ill be doing something destructive - but it does get bumped every now and then - so if it does get scarred up the bezel is replaceable. I have many G shocks and this is the most expensive one out of them so far. They make plenty of other options if you want something you don’t have to care about. I recommend the square face model if thats what you want. Its a basic watch, easy to read, small, thin, practically weightless and only about $40. This mudmaster is not that. While I’m sure it will hold up to real abuse - i for one dont plan on finding out. I dont wear this everyday since i have others, but so far the screen protector has also held up nicely. That is available on Amazon too. I think i paid $303 for this watch, and now its down to about $280 in the ever changing amazon prices - so keep an eye on the prices if youre not in a rush.

A great watch at a very fair price!
The delivery went off without a hitch! The delivery man was courteous, knocked on the door to alert me that there was a delivery and I appreciated his demenior . He did a good job,The Casio G-Shock is the typical first class product that they all are, I set it to the correct time with the Bluetooth between the watch and the Smart Phone in a few minutes. It's a great time piece, I'll have it forever!

Beast of a watch
This is my second G Shock. My first was almost 10 years old and I literally beat the crap out of it. I still use it for knocking around the house, yard work and whatnot, and it's still going strong. I got this watch because I wanted a few additional functions, and also wanted to upgrade my look. The band is pretty stiff, but fits nicely around the wrist and is very comfortable once its on. The backlight is very bright, the white numerals stand out even in the sun. The negative display is a bit tricky to read in the daylight, and the backlight doesn't really help much. The compass, as far as I can tell, is pretty accurate. The thermometer works well, but if you're wearing it the reading will be skewed by your body temp, so you need to take it off for a bit. I'm still playing with other features, but it is easy to navigate through each one. The app makes setup super easy. Overall, I am pleased with the purchase, and with the number of compliments I've gotten so far.

Another excellent Casio Mudmaster, with one caveat
Absolutely fantastic Casio, super high quality and reliability as one would expect from Casio. Love it, except for one thing; I didn't realize that the crystal is "spherical" and it is not flat. I think they do this for better visibility, almost like a magnifying glass or for anti glare. What ever the reason, it drives me crazy! Not sure what it is, but not having a FLAT crystal bothers the heck out of me almost every time I look at it in light that reflects the fact that it is not flat. Other than that, as mentioned, it is EXCELLENT. Love the orange (although a bit of a faded/pastel orange in real life, not bright), band, and everything else about it. The crystal is not a deal breaker; I didn't return it, but keep it in mind...

My last Mudmaster, but not my last Casio.
I’m a contractor and I like sporty rugged watches. I have an assortment of Casios. I told myself this will be my last. Hmm, not sure about that. This watch is super easy to read. Numbers are large and legible. One touch and the illumination of the light is fantastic! No complaints at all. The band added flair and my favorite color is green and I have a few watches with green bands so I wanted something different. Orange is eyes catching but not too ostentatious. Using the App to set up the watch was a breeze. I also watched a few you tube videos before purchasing. The “Watch Geek” is great for learning about Casio watches. I like the watch very much. The band is new so in time it will probably break in. I like the the little indent to keep the band from moving. I have a Pro trek (Casio) that band is. Resin. Best type of band for me. More comfortable than this watch by far. I’ve found the Casio watches in the over $100 to $340 tend to be the better value. I’m a firm believer in you get what you pay for. I really don’t use the compass and alarm features. I wanted a watch that was attractive, rugged and sporty. Casio makes so many watches. Every time I glance at my watch I smile inwardly. It’s a handsome and manly watch. Proud to wear it. I’m dying for somebody to take notice of my Casio watches. It would make my day. Until then I’ll just admire it myself.

Very happy with the watch. At first I'm having second thoughts if this is fake or genuine casio watch due to its low price compare to other seller, but when it arrived, it was a genuine casio G SHOCK GGB 100 Mudmaster. And lastly, received the item two days after I placed the order, and it comes in good packaging. I will definitely recommend and buy from this seller ozdigitalwatch.

Just an awesome watch!!!! It looks even better in person, a butt load of features and its built like a tank. I own many watches and this is my second G-Shock Mudmaster, but I think this one might be my favorite out of them all. Tough as nails and really eye catching time piece!
