Accelerating the evolution of tough ness-driven design: A sturdy, high-precision pilot’s watch inspired by the challenges of the supersonic realm
The G-SHOCK MASTER OF G line embodies a passion for delivering performance in extreme conditions. The GRAVITYMASTER in particular has demonstrated ongoing innovation as a pilot’s watch designed to support missions in the sky.
To accelerate the pace of that evolution, the GWR-B3000 takes on the challenge of adapting toughness-oriented design to perform in an all-new domain. Guided by a single development concept — “Supersonic” — the watch draws inspiration from the astonishing performance of jets breaking through the sound barrier. The newly developed movement and tough construction elevate reliability and precision, ensuring dependable performance in the toughest environments.
At the heart of the timepiece is the newly developed TOUGH MVT.2 (Tough Movement 2) equipped with two special features: auto hand home position correction with shock detection, and magnetic field detection. The watch also employs a newly developed dual hollow case structure to deliver enhanced resistance to shock, centrifugal force, and vibration. These aviation-oriented specs are designed to ensure precision timekeeping in the most demanding cockpit situations.
The GRAVITYMASTER is driven by a passion for capturing the essence of the pilot’s watch, offering an instrument panel for the wrist that will never break, never stop, and never fail to keep precise time. Welcome to tireless determination to deliver ultimate toughness. Standing at the forefront of that challenge, the GWR-B3000 delivers the advanced performance it takes to break the toughness barrier and soar far beyond.

FEATURES
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.
TOUGH MVT.2
Developed in pursuit of ultimate precision, reliability, and practicality, the solar-powered analog movement TOUGH MVT. features 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. now features a function for detecting shocks, magnetic fields and other external disturbances that affect the accuracy of the time display. From everyday use to the most demanding environments, this technology takes timekeeping reliability to a whole new level.

Auto hand home position correction with shock detection
This evolution in auto hand home position correction utilizes an original Casio algorithm to consistently maintain correct hand position. Added to conventional auto correction at fixed intervals, the function instantly detects strong impacts to the watch and immediately corrects the hand position, enhancing the reliability of timekeeping accuracy.
* This illustrates the correction of the seconds hand. The actual function also corrects the hour and minute hands.
Magnetic field detection
The internal magnetic field detection sensor detects any strong external magnetic field that affects hand movement, temporarily stopping hand movement to prevent reference positions from shifting. Once the magnetic field disappears, the hands return to the correct position and operation resumes.
* This illustrates the movement of the seconds hand.
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.
Diverse functionality to support flight missions
The watch features dual-dial world time display, an essential function for aviation, allowing the time for two cities to be viewed simultaneously on the main dial and an inset dial. It also provides direct access to UTC (Coordinated Universal Time).
In addition, the flight log function syncs with a smartphone via the dedicated smartphone app. Pressing a button on the watch records the current time and position on a map within the app, providing a useful way to manage departure and arrival times, as well as takeoff and landing locations.
Bio-based resin
Key resin components used in the center case and band are made with bio-based resin, a material expected to help reduce environmental impact.
