  • Terrific Watch!
What I needed was a highly durable watch, very easy to read, with no hassle in keeping it on the correct date and time. This watch meets all of the criteria and looks very nice! The ability to synchronize this watch to my iPhone with the Casio App turned out to be exceptionally useful and very helpful. I was concerned that this watch did not have a solar battery; however, I am actually getting more use out of it with a regular battery which simply needs to changed out, approximately every two years. You will love this watch! ... show more

  • Great watch
I was sick of having to charge up my other "smart" watch, thus I wanted something that had a regular battery, a traditional watch face and a step counter...not easy to find.....This casio Mud resist, ticked off all those boxes! It feels solid and looks sharp. The watch face is huge, took some adjusting, but no issues with the fit. Came in the box and tin. Very happy with the purchase. ... show more

  • A great and affordable watch with very useful features!
I love being able to control all of the features of this watch with an app on my cellphone. My favorite features are to be able to track barometric data; to track my activities; world time; alarms; step tracker with calorie count; locator function for where I park my car, and easy to read dial at night. The only I would wish would be a louder tone for my old ears. Having great fun with this amazing watch! ... show more

  • Light Weight and Comfortable to wear for a large watch
The watch looks great if you like larger watches and is so light weight that it's comfortable to wear all day. I have Invicta watches that you can't say that about. The G Shock Connected app makes setup and control of the watch easy and the four sensors work great There are some great YouTube videos explaining how to use the watch also. Overall a great watch. ... show more

  • Overall great watch but needs improvements.
Been wearing this beast for a couple weeks now. Here are the things I like so far. Comfort- Casio has a way of making these big watches wear so well, lightweight, as it curves to the top of your wrist so nicely and mold to your arm. Looks- I think a lot of people buy the mudmaster for this reason, this is a bold looking watch that is easy to read. I enjoy the new carbon case design here as well as the dial. The carbon fiber bezel really sets this watch off. Functionality- Having owned a gravitymaster with Bluetooth in the past, the ability to pair via Bluetooth with your phone and set up this watch is a nice feature that I was hoping would come to the lower priced Mudmaster. I love the find your phone feature on this watch! There are however a couple issues with this model that I hope Casio address is in future models. Thermometer- The thermometer works although it takes 30 to 45 minutes off the wrist to get an accurate reading. Mine did need adjusting as it was inaccurate out-of-the-box. Since this watch communicates with the phone to update time and timezone information I don't understand why Casio didn't have the option to bypass the incredibly slow temperature sensor and read the local temperature from your phone and transfer it to the watch. It's almost like Casio was too afraid to make this too much like a smartwatch, but they already have one toe in the pool here, just go all in. I think the user should have the option in the app to bypass the sensors and pull the temp and weather information from a phone. Lack of solar- initially I wasn't going to complain about this because this watch is not competing with the higher-priced G-Shock that has solar power and sapphire glass. I do however believe this would be a nice touch to all the G shock watches once they get up in this price range. Hopefully we'll see it in future models at this price point. Pedometer- personally I have no idea why they threw this feature on here other than for gimmick. I doubt anyone is seriously going to use this much and once again this is something that your phone can do. Why spend the money on an extra sensor and waste space inside the watch when you could just have the watch read that information from your phone. The negative digital display- I really hope they stop doing this on the mud Masters. This is just too hard to read in many lighting conditions. ... show more
