In person, you can feel the premium quality; it's very well made and gives a very good impression. Although this is the Mudman series and I believe it is resistant to everything, I still wouldn't want to throw it against rocks – the metal bezel is more expensive to replace than the rubber ones from the lower series.

Casio G-Shock Master of G Premium Mudmaster GWG-B1000-3AER Watch
A modern timepiece, recognized as one of the toughest models in the Master of G series, delivers exceptional resistance against mud splashes and sand intrusion. With a robust water resistance rating of 20 bar, immersion is possible up to depths of 200 meters. The case is crafted from scratch-resistant sapphire glass combined with a Carbon Core Guard constructed from carbon-reinforced resin. An anti-reflective coating on the glass ensures clear readability under bright sunlight. Internal mechanisms receive superior protection thanks to a layer of AlphaGel, designed to absorb shocks and shield the movement from intense impacts.
Solar mechanism, Full-Auto LED illumination
A solar mechanism driven by solar energy and utilizing Tough Solar technology ensures reliable and accurate timekeeping. The combination of hands on the dial and a digital display provides digital-analog time indication. Every hour, an automatic hand adjustment system monitors and, if necessary, corrects hand alignment. Full-Auto LED backlighting and the application of Neobrite luminescent coating on both the dial and hands guarantee visibility and usability in dim conditions or total darkness.
Numerous sensors
Designed for superior thermal insulation (effective for both hot and cold beverages), the model also offers outstanding resistance to mechanical impact.
The temperature of the contents (water, 98 deg. C) was recorded as follows:
- After 6 hours - 70 deg. C
- After 12 hours - 60 deg. C
- After 24 hours - 40 deg. C
Testing was performed at an ambient temperature of +20 deg. C (+/- 2 deg. C).
Flexible strap
A strap crafted from flexible material, secured with a metal buckle, guarantees a comfortable fit of the watch on the wrist. The selected material is highly resistant to moisture and sweat, ensuring reliable performance during a range of activities.
Bluetooth technology, Casio Watches app
Outfitted with Bluetooth technology, the watch enables seamless communication with mobile devices operating on both Android and iOS platforms.
By using the Casio Watches app, users benefit from automatic time synchronization and can fine-tune the watch to match their personal settings. The application also provides the functionality to choose from over 300 time zones and keeps a record of previously visited locations. Additionally, a find your phone feature empowers the watch to activate a high-volume alarm on the paired phone when both devices are within range, greatly assisting in locating your device.
Automatic connection to the smartphone verifies time precision, and the watch corrects itself as needed to ensure accuracy.

Casio is a Japanese brand founded in 1946, which has remained one of the most recognizable consumer electronics manufacturers in the world for decades. It gained global fame with its iconic G-Shock series from the 1980s, valued for its high resistance to shocks, water, and extreme conditions. The company consistently develops its technologies, introducing innovations such as Tough Solar - a solar power system - and Wave Ceptor - radio time synchronization. Casio watches are popular among professionals and people looking for reliable models for everyday use and outdoor activities. The first G-Shock (model DW-5000C), designed in 1983 by engineer Kikuo Ibe, was so durable that it was tested by dropping it from the tenth floor, and yet it still worked flawlessly. Today, Casio is a symbol of innovation, durability, and timeless style.

This is already my next G-Shock. In addition to being reliable and indestructible, they are simply very nice. I like this sporty-military style, but without any weird features. This certainly won't be my last Casio watch.
-
My next G-Shock, this time from the MUD Master series, and once again, it's top class in itself. The watch is beautifully made, works seamlessly with my phone, and the navigation has been checked and works properly. Honestly, highly recommended!

Perfect as a companion in the field. Compass, thermometer, altimeter—everything that can help on the trail. Large, but lightweight and very comfortable to wear. I recommend it.

Great watch. Practically resistant to everything. This is already my third from the Mudmaster series, each has been through a lot and still works today. I recommend it to everyone. Solar charging means it will last forever. This version of Mudmaster has Bluetooth only for watch settings via smartphone, which is a pretty cool feature.
