G-SHOCK expands the Master of G lineup with the launch of the GRAVITYMASTER GWR-B3000, a professional aviation instrument designed to withstand the strict demands of modern aerial navigation. The highlight of this release is the inclusion of the TOUGH MVT.2 caliber—the next evolution of the Japanese brand’s solar-powered analog movement—which integrates digital algorithms and specialized sensors to prevent timing misalignments caused by extreme impacts or cockpit magnetic fields.
Dual Hollow Architecture and Triple G Resist Technology
The design of the GWR-B3000 is the result of deep topological optimization analysis conducted through computer simulations. Its construction relies on a dual hollow case structure where the central core is suspended by four contact points. The inner housing, made of bio-based resin and reinforced with carbon fiber under the Carbon Core Guard architecture, encapsulates the movement to shield it from direct stress.
Meanwhile, the outer framework combines stainless steel components crafted through Metal Injection Molding (MIM) with visible resin dampers. This technical integration delivers Triple G Resist certification, guaranteeing seamless watch operation against three types of gravitational acceleration: direct shocks, centrifugal forces, and high-frequency vibrations.
TOUGH MVT.2 Caliber: Magnetic Protection and Automatic Correction
In terms of mechanics, the new TOUGH MVT.2 analog movement combines Tough Solar power with maximum precision delivered via Multiband 6 radio control and Bluetooth® connectivity through the CASIO WATCHES app. However, its most significant technical advancement centers around two active protection systems:
First, an internal magnetic sensor detects intense surrounding electromagnetic interference and temporarily halts hand movement to prevent reading errors. Once clear of the magnetic field, the system resumes exact timekeeping. Second, a mini optical sensor checks the home position of the hands every hour; in the event of a severe shock, an immediate correction algorithm repositions the hour, minute, and second hands back to their exact location.
Instrumental Legibility and Flight Connectivity
The deep black dial features micro-textured surfaces engineered to diffuse ambient light and eliminate glare under direct sunlight. To maintain a clean, high-contrast aesthetic, the Tough Solar panels are integrated exclusively into the sub-dials. The entire assembly is protected by a spherical sapphire crystal with anti-reflective coating and illuminated by a high-intensity Super Illuminator LED light.
Tailored for flight missions, the watch provides direct access to Coordinated Universal Time (UTC), simultaneous dual time display, and a dedicated Flight Log function. The latter allows pilots to record their geographic location and exact timestamp on an interactive map with a single press of the dedicated watch button.
Heritage & DNA
The G-SHOCK Identity: Pushing Toughness to the Limit
G-SHOCK is the timepiece that redefined the concept of toughness in modern watchmaking. Its origin traces back to a bold challenge against conventional wisdom, driven by a designer’s conviction that it was possible to construct a watch that would never break, even when dropped. In 1981, the iconic Project Team Tough was formed to realize this vision, testing and developing over 200 prototypes step by step across two years until successfully devising a shock-resistant core structure. That breakthrough marked the inception of an unprecedented engineering philosophy.
Since that milestone, G-SHOCK has pursued relentless evolution across all fronts—from advanced materials and structural engineering to functional utility. Today, those constant development efforts culminate in technologies like Triple G Resist, an architecture engineered to withstand three distinct types of gravitational acceleration. Coupled with the intuitive operation of systems like Smart Access, the brand continues to deliver reliable instrumentation under the most grueling flight conditions. A commitment to absolute toughness that remains stronger than ever.
