## Description

The MUDMASTER from G-Shock's Master of G line, was made for comfort and functionality in the toughest environments. It's solar powered, radio-controlled and has a triple sensor (compass, altimeter/barometer, and thermometer). It also has a mobie link through Bluetooth.

Review: Classier Looking Mudmaster! - Recently sold my GWG-2000 which I had for two years and was missing the G-Shock experience so bought this here on desertcart. I'll come right out and admit that the maroon band was what sold me lol. Otherwise this is a solid G-Shock with all the features including sunrise and sunset which my previous watch didn't have. Pros: Red band Rose gold accents All the bells & whistles including Tough Solar, Multi-band 6, and Bluetooth Bluetooth connects to Casio app and makes setting up the watch way easier than doing it manually. Cons: Light is not as bright as GWG-2000 and is at the 4 o'clock position which leaves some of the watch in a slight shadow when used. Metal keeper. Why? NOTE: Casio has fixed the radio sync problem with this model but be aware that if you pair the watch to BT it will attempt to connect to this for time sync overnight and will not connect to the radio signal. To connect to the radio signal just un-sync the watch using the instructions found on the Casio web page and it will sync to the atomic clock overnight. All-in-all a nice watch and visually a step up from previous Mudmasters.
Review: I love it - I have came to love mudmaster series. This one specifically is really good looking, built like a tank, and has everything. I like how it has bluetooth for settings and time sync, but its not reliant on it. Some of the bluetooth functionality is a bit gimmicky and is basically a shortcut for the app functionality.
