Description

Twin Sensor model from the G-Shock Mudmaster Series, designed for use in extreme environments scattered with rubble, dirt and debris. With a push of one large button at the 3 o'clock position, you can check your position with its Compass. The temperature can also be measured easily by pushing the button at 4 o'clock. This model has been developed with operability in mind so that anyone can intuitively check their position using the Compass, even in the most extreme climates, without visual observation. The dust and mud-resistant button guard cylinder structure prevents fine sand and mud from getting into the buttons while also helping to absorb any shock to the buttons and improving operability. Broad hour/minute hands and indices of large Arabic numerals have also been adopted to improve visibility. This design is packed with military-style flare, including a mode display that uses a sprocket- inspired disk dial and a textured band to prevent slipping.

Great Watch and No Batteries
The watch looks great. With the coating on the hands and the LED it’s easy to read the watch even in lower light. At first for me the watch seemed too big but after wearing it for 24 hours I now feel that the size is just right. At my age I have to use readers on most small print but on this watch I can read all of the needed info. I accredit this to the size of the watch and the high contrast colors they use. I chose this Mud watch because it is solar powered and it isn’t crowded with too many features. The extra features on it are compass and temperature. Compared with my Jeep Compass and my Suunto Compass it is accurate enough for general work. This watch is directly from Casio in Japan so the instructions are in Japanese. If you have ever owned a multifunctional Casio watch you will have no difficulty in setting it up. Remember the digital time display that you set up is what sets the hands. I bought some watch crystal covers which are cheap and I have had good luck with them in the past. I like everything about this watch so far and if anything changes “I’ll be Back” (yes I use my right wrist) ... show more

Good watch
This is a great watch. Keeps good time, for the most part. Has a second hand and a light. My only wish would be for it to be atomic so it would automatically adjust the correct time with the time station in Ft Collins CO. I have one that is and I have NEVER had a more accurate timepiece.

Rugged and Reliable Everyday Watch
I like the combination of analog and digital features, which makes checking the time and functions very convenient. Overall, it feels durable, comfortable on the wrist, and designed for practical, long-term use.
