My GShock

Reach new heights and break new barriers with a GRAVITYMASTER inspired by the exhilarating speed of supersonic jets. From the G-SHOCK MASTER OF G line of timepieces that deliver peak performance for professionals facing punishing conditions on land, in the sea, or in the sky — this timepiece combines durability and functionality to meet the demands of rigorous aerial missions. Employing a dual hollow case structure, the advanced TOUGH MVT.2 movement, and outstanding readability, the GWR-B3000 ensures the precision timekeeping required for professional missions flown from the most demanding cockpit situations. Topology analysis of spatial relationships is used to optimize the exceptionally rugged GRAVITYMASTER design for Triple G Resist. The Triple G Resist structure enhances the watch’s ability to withstand shock, centrifugal force, and vibration, with these previously independent functions now working interdependently within a dual hollow structure. The dual hollow structure features an outer case enveloping the center case and supporting it at separate four points, making the center case appear to float. The outer case is constructed of multiple components finished with metal injection molding (MIM), incorporating resin buffering components, as well. The shock absorbers that protect the center case are left visible, creating a design of complex and intricate structural beauty. Developed in pursuit of ultimate precision, reliability, and practicality, the Tough Movement solar-powered analog movement has now evolved to become the TOUGH MVT.2, featuring advanced self-regulating control that withstands external disturbances. Tough Solar power ensures the stable operation of auto time adjustment and auto hand home position correction. In addition to hybrid mount construction for outstanding durability, TOUGH MVT.2 newly incorporates a function for detecting shocks, magnetic fields and other external disturbances that affect the accuracy of the time display. When the watch detects a strong impact, the auto hand home position correction function immediately repositions the hands to the proper setting. Similarly, if a strong external magnetic field is detected, the hands temporarily stop moving and automatically return to the correct position once the magnetic field disappears. A newly developed dark black dial features microfabricated surface textures to diffuse light and reduce reflection, boosting contrast and ensuring clear visibility in any environment. Combined with an in-dial solar system — inset dial solar panels that capture enough light to power the watch — the result is a dial color with rich depth. Scratch-resistant, highly transparent sapphire crystal enhances clarity, and environmentally friendly bio-based resin for the band and center case help reduce environmental impact. The innovative tough style delivers full-on practical functionality, as well. Download the CASIO WATCHES app and pair with your smartphone via Bluetooth® for automatic time correction and access to flight logs. All of this, together with high-intensity LED light, direct access to UTC (Coordinated Universal Time), and other extremely practical functions, earn this supersonic GRAVITYMASTER a worthy place among the MASTER OF G family of full-fledged pilot’s watches.

TOUGH MVT.2: An all-new pursuit of timekeeping precision

The further improved TOUGH MVT. (Tough Movement) delivers timekeeping with even greater precision.

Two new features have been added: auto hand home position correction with shock detection, and magnetic field detection. Auto hand home position correction with shock detection instantly detects impacts to the watch and corrects any hand misalignment. Accurate time display is maintained even when the watch is subjected to strong impacts in the cockpit. Magnetic field detection temporarily stops hand movement when the sensor detects a strong magnetic field. Once the magnetic field disappears, operation is resumed with accurate timekeeping.

Combining these two detection functions driven by advanced digital technologies with a movement featuring radio control, solar power, and Bluetooth® connectivity, the GWR-B3000 delivers durability and timekeeping precision as a genuine pilot’s watch. The timepiece maximizes performance during demanding flight missions in extreme conditions.

An optimal solution for ultimate toughness

Triple G Resist, the GRAVITYMASTER line’s proud symbol, is a structure engineered to withstand three types of gravitational acceleration: shock, centrifugal force, and vibration. It has been reengineered with a brand-new exterior designed to help withstand impacts to each component.

The hollow structure, which has protected the movement from direct impact since the first G-SHOCK, is further strengthened with a dual inner and outer case design. Carbon fiber-reinforced resin delivering both strength and lightness is used for the inner case, while the outer case is constructed of stainless-steel protectors finished with metal injection molding (MIM) and shock absorbers made of resin.

The dual hollow case structure — composed of multiple components with complex shapes — was created using topology optimization, a form of computer-aided engineering analysis. Extensive simulations were conducted to evaluate three types of stress: impact, centrifugal force, and vibration. Using advanced engineering techniques, each component’s shape was optimized to achieve an exterior design that balances durability with aesthetic appeal.

Reliable readability: An instrument panel on the wrist

To accurately convey the information needed by pilots in the cockpit, which may undergo extreme gravitational acceleration, the GWR-B3000 features a design that gives maximum priority to ensuring readability.

The wide, dimensional face offers a broad viewing angle and features large hands and indexes enabling the time to be read at a glance, even while piloting an aircraft. A newly developed dark black dial, crafted using proprietary precision processing technologies, enhances contrast by accentuating light and shadow. Microfabricated surface textures on the dial reduce light reflection, improving visibility in direct sunlight and other ambient light conditions.

Combined with an in-dial solar system — where the solar-receptive area in the inset dials alone transmits enough light to power the watch — the design achieves a deep, opaque dial color. This integration of practicality and functional beauty elevates the GRAVITYMASTER line’s aviation style to an even higher level of perfection.

Light, comfortable fit on the wrist

The soft urethane band provides a soft, comfortable feel on the wrist while offering outstanding durability. It features a dual-layer construction with an optimized thickness for a more secure fit and is finished in a two-tone color scheme on the top side and underside. The band for the GWR-B3000B is available in three color options, blue, gray, and black, with each color scheme coordinated with the dial and case for a unified look.
