In many countries, it also sets itself automatically to summer and winter time.

Giving you a constant overview: Elements on the display are distinguished from one another using colour. This is achieved using different coloured layers placed on top of one another, allowing information to be displayed more clearly.
Barometer (260 / 1.100 hPa)
A special sensor measures the air pressure (measuring range: 260/1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends.

Altimeter data memory
Depending on the model, up to 40 sets of elevation data can be stored in the watch's data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored.
World time function
Displays the current time in major cities and specific areas around the world.
Timer - 1/1 min. - 24 hours
For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest seconds and up to 24 hours in advance. This model has three independent timers - ideal for people who need to take medicines every day or those who do interval training.

This is my latest G-SHOCK, but this Mudman takes durability to a whole new level. Its special mud- and dust-resistant design means I don’t have to worry about it even in the roughest off-road conditions. The barometer and thermometer are very accurate, which helps me monitor the weather on the trail. I really appreciate the Super-Illuminator backlight—the face is perfectly visible at night. The watch looks rugged and sporty, and you can feel the quality of the durable resin construction the moment you take it out of the box. I recommend it to anyone who needs a reliable tool for special tasks.

For me, the biggest advantages are the solar power and the radio-controlled feature. The watch automatically syncs the time with an atomic clock, so I always have the time accurate to the second without having to set it manually. The display is very easy to read, and the dual-layer dial with a digital compass is a brilliant solution that makes navigation easier. Additionally, the barometer and thermometer work flawlessly and are very helpful for monitoring the weather. Despite its 53 mm case width, the watch is lightweight and comfortable thanks to its durable resin construction. The Super-Illuminator backlight ensures full readability in complete darkness. If you’re looking for a maintenance-free, rugged piece of gear that won’t let you down in any conditions, the Mudman is the best choice. It’s a solid tool for anyone who values reliability in the field.

A cool feature of the watch that isn’t often mentioned is the power-saving mode, which automatically turns off the display when the watch is in the dark. The LED backlight can be set to 1.5 or 3 seconds.
The battery life of the Casio G-SHOCK watch is approximately 6 months (operating time under normal use without exposure to light after a full charge) or 26 months on the battery (operating time when the watch is stored in complete darkness with the power-saving function enabled after a full charge).
