Take on every mission with the GRAVITYMASTER, inspired by the incredible speed and performance of supersonic aircraft. Part of the G-SHOCK MASTER OF G collection, it is engineered for professionals operating in the harshest conditions across land, sea and air. Designed to meet the demands of modern aviation, the GWR-B3000 combines exceptional durability, advanced functionality and outstanding legibility. Featuring a dual hollow case structure, evolved TOUGH MVT.2 movement and Triple G Resist construction, it delivers the accuracy and reliability required in the most demanding cockpit environments. The GRAVITYMASTER’s rugged design is optimised using topology analysis to maximise the performance of its Triple G Resist structure. This advanced construction provides protection against shock, centrifugal force and vibration, with each element working together to enhance overall toughness. Its innovative dual hollow case design suspends the centre case within an outer case supported at four separate points, creating the appearance of a floating structure. Metal injection moulding (MIM) components and strategically placed resin buffers provide additional protection, while visible shock absorbers showcase the watch’s intricate engineering. At the heart of the GWR-B3000 is TOUGH MVT.2, the latest evolution of Casio’s solar-powered analogue movement. Developed for exceptional precision, reliability and durability, it features advanced self-regulating control designed to resist external disturbances. Powered by Tough Solar technology, the movement supports automatic time adjustment and hand position correction. It also detects shocks, magnetic fields and other factors that could affect accuracy, automatically restoring the hands to the correct position whenever needed. A newly developed dark black dial uses micro-engineered surface textures to reduce glare and improve contrast, ensuring excellent readability in a wide range of lighting conditions. Integrated solar panels are discreetly built into the dial, delivering efficient power generation while maintaining a rich, deep finish. A scratch-resistant sapphire crystal further enhances clarity, while bio-based resin components used in the band and centre case help reduce environmental impact. Pair the watch with the CASIO WATCHES app via Bluetooth® for automatic time updates and access to flight log functions. Additional features include a high-intensity LED light, direct UTC access and a range of practical tools designed to support pilots wherever their journey takes them. Combining advanced technology, exceptional toughness and aviation-inspired design, the GRAVITYMASTER earns its place within the MASTER OF G family of professional pilot's watches.

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 case, bezel, and band are made with bio-based resin, a material expected to help reduce environmental impact.
