The Casio G-SHOCK Mudman GW-9500-1A4ER watch is a solid piece of equipment with a black and red color scheme. The strap and case are made of resin. Underneath the mineral glass is the display, which allows functions such as Day Date, 24-hour time format, stopwatch, LED backlight, 5 daily alarms, barometer, digital compass and world time. A Japanese solar radio-controlled mechanism with a charge indicator is responsible for the accurate operation of the whole thing. The water resistance of the product is 200 meters.

Radio signal reception (EU, USA, Japan, China)
Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China - once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time.
Duplex LCD
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.
Thermometer (-10°C / +60°C)
A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).
Digital-compass
A built-in direction sensor detecs the magnetic north.
10 000 m altimeter
A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10 000 m.
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.
5 daily alarms
The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments.
Snooze feature
Each time you stop the alarm, it sounds again after a few minutes.
Button tones on/off
The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated.
Automatic calendar with Date, Day and Month
Once set, the automatic calendar always displays the correct date.
12/24-hour timekeeping
Times can be displayed in either a 12-hour or 24-hour format.
Mineral glass
The tough mineral glass resists damages.
Folding clasp
The watch has a folding clasp.
Battery level indicator
An indicator shows the current battery level.
Water resistance classification (20 bar)
Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810.
The sturdy plastic envelope makes a good impression. I'm satisfied.

The G-SHOCK Mudman GW-9500 is a true beast built for special missions. I was looking for a watch that could withstand literally anything, and this model more than meets those expectations. The construction is incredibly rugged, and the mud- and dust-proof seals ensure that the watch won’t let you down in the toughest off-road conditions. The biggest plus for me is the solar power and radio-controlled time. I don’t have to worry about changing batteries or setting the time—the watch syncs automatically with an atomic clock, so I always have the exact time down to the second. The display is easy to read, and the red accents on a black background give it an aggressive, technical look.

I chose this model because I was looking for an uncompromising, rugged watch that could handle the toughest off-road conditions, and the Mudman series has long been synonymous with total durability. The black-and-red design gives it an aggressive and modern look, and the massive 53 mm case makes the watch look like a professional tool for special missions on the wrist. The biggest advantage of this watch is its radio-controlled technology, which, combined with solar power, makes it virtually maintenance-free and ensures it always displays the exact time thanks to synchronization with radio waves. Additionally, the special mud- and sand-resistant construction gives me confidence that no dirt will affect the operation of the buttons or the movement during off-road expeditions. The package is rounded out by advanced features such as a digital compass, barometer, and thermometer, which turn it into a true command center on your wrist. It’s the perfect choice for anyone who needs reliability and exceptional durability in a modern and functional design.
