Master of G Mudman GW-9500MRY-1A9ER Watch

The Watch

The Casio G-Shock Mudman is a must-have for fans of rugged, masculine timepieces. Built with a resin case, it delivers the toughness and durability you expect from the legendary Japanese manufacturer. The round case measures an impressive 52.80 mm in diameter, giving the dial plenty of real estate to appreciate every detail. At 14.80 mm thick, the watch commands a bold presence on the wrist while maintaining solid construction and functionality. Its dynamic color scheme pairs vivid yellow with sharp black accents, underscoring its sporty, daring character. The carbon bezel features ion-plating, adding a modern, high-tech edge. For added durability, the case uses a screw-back - a hallmark of quality watchmaking. At 88 g, the watch sits comfortably on the wrist without sacrificing comfort during extended wear.

The Dial

The Mudman's dial uses LCD technology for a clear, sharp readout thanks to its digital display. The gray color contrasts elegantly with the dark bezel, creating a striking visual aesthetic. Arabic numerals make the digital display intuitive and easy to read. The dial also features a Full Auto LED backlight, ensuring effortless readability even in total darkness - invaluable during night adventures or in low-light environments. A flat mineral glass crystal shields the entire dial from scratches and damage, protecting the display for the long haul. The watch's design also incorporates multiple complications, including a 1/10-second stopwatch, countdown timer, and GMT, altimeter, barometer, and thermometer functions - meeting every need for performance-driven, practical users.

The Functions

Full Auto LED Backlight

In low-light conditions, tilting your wrist automatically activates an LED to illuminate the dial.

Shock Resistance

The shock-resistant structure protects the watch against impacts and vibrations.

Solar Operation

Invisible solar cells inside the watch convert light into energy to power all functions. A rechargeable battery provides the capacity needed to keep the watch running in low-light conditions.

Automatic time sync via radio-controlled signals (EU, USA, JPN, CHN)

Whether you're in Europe, North America, Japan, across Canada, Central America, or China - once the watch is set to the local time zone, it picks up the corresponding radio signal and always displays the exact date and time. In many countries, it automatically switches between daylight saving time and standard time.

Duplex LCD

The dual-layer LCD screen displays compass graphics on the top layer, while the bottom layer provides a large readout of the time and various measurements.

Barometer (260 / 1,100 hPa)

A built-in sensor measures local atmospheric pressure and displays it on screen - useful, for example, on a hike to spot changing weather trends before they hit.

Thermometer (-10°C / +60°C)

A built-in sensor measures the local temperature and displays it on screen.

Digital Compass

A direction sensor detects magnetic north and displays it on the watch, along with your current heading.

Altimeter 10,000 m

A built-in sensor measures local atmospheric pressure and calculates current altitude.

Altimeter Memory

The watch features a memory that can store up to 40 altitude data logs - depending on the model - which can be reviewed at any time. Each data block includes the recorded altitude along with the date and time of the measurement. In addition to the measured altitude, the altimeter also logs the maximum and minimum altitude recorded in a session.

Sunrise/Sunset Indicator

Once you enter your local data - date, time, and location - sunrise and sunset times can be displayed for any other date.

World Time Function

The world time function displays local time across 29 different time zones.

Stopwatch Function - 1/10 sec - 1,000 h

Precisely measures elapsed time at the press of a button. The fraction indicates the unit of measurement, while the number shows the maximum time that can be timed.

Countdown Timers - 1/1 min - 24 hours

For precision lovers: countdown timers alert you to important or recurring events with an audible signal at the programmed date and time. Time can be set in minutes, up to 24 hours in advance - a particularly handy feature for daily medication reminders or repeated training intervals.

5 Daily Alarms

A daily alarm reminds you of your deadlines at the scheduled time. This model features five independent alarms for maximum flexibility in tracking your important appointments.

Snooze Function

Every time you dismiss the alarm, it goes off again a few minutes later.

Button Beep On/Off

The button beep can be turned off using the mode button. Once deactivated, no beep sounds when switching between functions. However, any programmed alarms or countdown timers remain active after the button beep is disabled.

Auto-Calendar

Once set, the auto-calendar always displays the correct date.

12/24-Hour Time Format

Time can be displayed in either 12-hour or 24-hour format.

Battery Level Indicator

The Movement

Powering this watch is a Japanese solar movement by Casio, delivering outstanding precision and reliability. Solar-powered and eco-friendly, it offers an impressive power reserve of up to 6 months - no battery changes needed, saving both time and money. The movement also packs advanced features including a high-precision stopwatch, Dual Time function, and daily alarms for optimized time management. A built-in radio-controlled system automatically syncs with universal time, so you're always on the dot, wherever in the world you are.

The Strap

The yellow resin strap perfectly complements the case's energetic aesthetic. Resin construction makes it both durable and comfortable - essential for everyday wear or intense outdoor activities. Secured with a gray pin buckle, the strap delivers a secure, custom fit around the wrist so adventurers can stay focused on the action. The lug width is also precisely tailored for a seamless fit, reflecting careful attention to detail and quality. This closure style is especially practical for sports enthusiasts - secure, easy to operate, even with gloves on.

Water Resistance

Water-resistant to 20 atmospheres, the Mudman is built to handle extreme conditions - from light dives to intense surf sessions. That makes it the perfect companion for explorers and water sports enthusiasts alike. Rated to withstand pressure equivalent to a 200-meter immersion, it reliably keeps out water and dust, giving you total peace of mind in aquatic environments. Its water resistance is backed by the rugged resin case construction and advanced technologies including a screw-down crown and seals engineered for wet, hostile conditions. The result is a watch that's as much a performance tool as it is a bold style statement - the Casio G-Shock Mudman stays functional and sharp no matter what the elements throw at it.
