Enjoy both fearless adventure and a comfortable fit with this tough and rugged Master of G Mudmaster flagship timepiece.



Bluetooth® Smart

The watch is equipped with Bluetooth® low energy technology that allows data exchange at the touch of a button to save energy. The watch connects to your smartphone wirelessly via Bluetooth®, giving you access to many useful functions.

Smartphone time

If the watch is paired to the smartphone, the time is automatically adjusted and the current time is displayed for everyone.

Fully automatic LED light

An electroluminescent (EL) panel causes the entire watch face to illuminate for easy reading. The automatic light function activates the EL backlight whenever you tilt the watch towards your face for reading.

Shock resistant

The case is shock-resistant and protects against impact and vibration.

Dirt-resistant casing

The case and buttons are equipped with special seals to prevent dust and mud from entering.


Strong magnetic fields don't stand a chance with this watch. The module shield protects the electronics and prevents any disturbance.

Solar energy system

The invisible solar cells of the watch convert light into energy and power all functions. A rechargeable battery provides the necessary capacity to operate in low light conditions.

Reception of DCF/MSF/WWVB/JJY/BPC radio signals

Whether in Europe, North America, Japan or in Canada, Central America and China, once the clock has been set according to the time zone in which it is located, it receives the corresponding radio frequency signal in order to always display the exact time. In addition, in many countries, daylight saving time and winter time are automatically activated.

Barometer (260 / 1,100 hPa)

An integrated sensor measures the local atmospheric pressure and shows it on the display. This can be useful, e.g. during an excursion, to recognise weather trends at an early stage.

Thermometer (-10°C / +60°C)

An integrated sensor measures the local temperature and shows it on the display.

Digital compass

A direction sensor measures magnetic north and displays north on the watch as well as the direction in which you are moving.

Altimeter 10000 m

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

Altitude sum

With the altitude sum, you can add up all the metres you have climbed. This function allows you to see at a glance the total difference in altitude that you have climbed during a trip.

Altimeter memory

Up to 40 altitude data sets can be stored in the watch memory (depending on the model) and can be called up at any time. Each stored data set consists of an altitude measurement in combination with a date and time. In addition, the maximum and minimum heights during the measurement are also saved together with the height data.

Sunlight indicator

After entering local data such as date, time and location, sunrise and sunset times can be displayed for any other date.

Mission Log

After activating the track log function, the route and altitude profiles are stored in the smartphone and can be viewed on a map. They are also automatically stored in a track log.

Location indicator

The location indicator indicates the direction and distance to a previously stored location. This function can be very useful if you got lost and want to return to a cabin, a lake or a car.

World time function

The world time function displays the local time in up to 29 different time zones.

Stopwatch - 1/100 sec. - 24 hours

Accurate elapsed time measurement at the touch of a button. The fraction indicates the unit of measurement, while the time figures indicate the maximum time measurements.

Timers - 1/1 second - 1 hour

For all those who demand precision: countdown timers are very useful for reminders of special or recurring events, as they emit an acoustic signal at the programmed time. They can be set by the second or up to 1 hour in advance. Particularly practical for daily medication or interval training.

5 daily alarms

The daily alarm reminds you of recurring daily appointments with an acoustic signal that sounds at the set time. This model is equipped with 5 independent alarms to remind you of your important appointments.

Automatic hand adjustment

The automatic hand adjustment checks the initial position of the hands and corrects them every hour if necessary (in case of deviation due to shocks or magnetism).

Button sound activated/deactivated

If desired, it is possible to deactivate the button sound with the Mode button. Once deactivated, the clock will stop beeping when changing from one function to another. The set alarms or the countdown timer are still active after deactivating the button sound.

Hand movement function

By pressing the button, the hands start to move, allowing a clearer view of the stopwatch and/or date functions.

Crown lock

Secures the crowns against unintentional switching to another operating mode.

Smart Access Technology

The Smart Access system, via an electronic crown, gives you quick and intuitive access to all the important functions of the watch. By pressing and turning the crown of the watch, you can switch between the different modes to operate functions such as the stopwatch, timer, alarm or universal time.

Phone Locator

Lost your smartphone? At the push of a button on the watch, the Smartphone will sound an alarm.

Automatic calendar

Once set, the automatic calendar always displays the correct date.

12/24-hour standard time display

The hours are displayed in either 12-hour or 24-hour format.

Sapphire crystal

The sapphire crystal is artificial and convinces with its hardness and scratch resistance. It prevents the watch from being scratched or the glass from fogging up.

Carbon-reinforced resin case

Due to its extreme durability, resin is the ideal material for watches. In combination with carbon, another particularly resistant material, we have designed a case that is less vulnerable to external influences and has a better load-bearing capacity, which means a much longer service life.

Sustainable resin bracelet


The bracelet is equipped with a buckle.

Low battery indicator

An indicator shows the current battery level.

Water resistance rating (20 bar)

Perfect for free diving without equipment: the watch is water resistant up to 20 bar (ISO 22810).
