GWG-B1000-1A4ER

My GShock

The tactical powerhouse that needs no introduction, the MUDMASTER range has been a firm favourite of adventurers, military operatives and G-SHOCK fans since its first release in 2015. The GWG-B1000 is now issued with Bluetooth built in as standard together with Mission Log & Location Indicator modes. Essential when exploring new areas the watch works in unison with the CASIO WATCHES APP. MISSION READY Representing the premium line of MASTER OF G the new B1000 evokes a high grade finish with a  new steel bezel, diamond carbon shock absorbers and bio-based carbon fibre guard structure. ADVENTURE PROOF As the name suggests the MUDMASTERs renowned environment resistance is back and stronger than ever. Regardless of the terrain or materials the watch is exposed to it will continue to operate and function.  A patented gasket system, 200m water resistance and ultra-reliable solar power ensure your MUDMASTER can go where you go. A built in Barometer monitors incoming weather fronts and alerts of sudden drops in pressure to get cover before storms. Thermometer & sun rise/set modes work alongside the watches triple sensor to keep you up to date on your surroundings.

Specifications

Feature

Tough design inspired by professional gear

Inspired by the adventurous spirit exemplified by tearing across the wastelands in “overlanding” style, the design incorporates the solid, rugged look of offroad vehicles and survival gear. With the multi-dimensional form of the multi-component structure, the large-diameter dial, and oversized buttons, the chronograph delivers durability, operability, and readability, with exterior design combining practicality with aesthetic appeal.

Guard structure integrating components made with different materials

The timepiece employs a newly developed guard structure that combines components made with different materials: stainless steel for the bezel ring, upper and lower bezel guards, and front button guard, and carbon fibre-reinforced resin* for left and right side button guards. For the bezel guards, the guard sections alone are cut out of components forged into bezel shapes. The complex moulded form of the front button guard is achieved with a high degree of precision using metal injection moulding (MIM). A diamond-like carbon (DLC) coating is applied to the materials’ surfaces to provide even greater abrasion resistance.

*Due to the characteristics of carbon fiber-reinforced resin, the pattern and color tone that appears on the surface will vary model by model.

Dust- and mud-resistance plus vibration resistance, to withstand use in the harshest conditions

The buttons are protected by cylindrical stainless-steel parts, and the button shafts are equipped with gasket fittings. The crown features a screw-lock construction to prevent contamination with mud and dust. Also, the sides and underside of the module incorporate αGEL to ensure vibration resistance.

*αGEL is a registered trademark of Taica Corporation in Japan and other countries.

Triple Sensor to stay on top of changing conditions

Includes a pair of compasses, an altimeter/barometer, and a thermometer. The second hand indicates north, while the indicator hand shows the recorded direction (bearing memory) and the direction to a point recorded in the app from the watch and/or a point manually set on the map within the app* (location indicator). These handy features help with checking the direction of a desired destination.

*In China, users are unable to manually set a point in the app.

Digital Compass

60-second continuous direction measurement.
Includes auto horizontal compensation.

Thermometer

Carbon Core Guard structure

DETAIL1

Carbon Core Guard structure

A carbon fibre-reinforced resin case* protects the module, making the most of the high degree of strength and outstanding durability delivered by the carbon material to achieve a size ensuring a comfortable fit.

*Due to the characteristics of carbon fiber-reinforced resin, the pattern and color tone that appears on the surface will vary model by model.

Attention to materials: Bio-based resin

DETAIL2

Attention to materials: Bio-based resin

Key resin components of the bezel, case, and band are made with bio-based resins. Produced using renewable organic resources, the material is expected to help reduce environmental impact.
