Casio is pushing the boundaries of aviation timepieces once again. Set for a July 2026 release in Japan, the highly anticipated G-Shock GravityMaster GWR-B3000 series has officially been announced. Dropping in three distinct colorways—the GWR-B3000-1A, GWR-B3000A-2A, and GWR-B3000B-8A—this new lineup brings next-generation structural engineering and ultra-refined movement technologies to the wrists of aviation professionals and extreme sports enthusiasts alike.

Here is a closer look at what makes the new GravityMaster series a definitive upgrade.

Built for the Skies: The Dual Hollow Structure

At the heart of the GWR-B3000 series is a newly developed "Dual Hollow Structure", achieved through advanced topology optimization. This design fully integrates Casio’s signature Triple G Resist system, meaning the watch is built to withstand extreme shock, centrifugal gravity, and intense vibrations.

The watch utilizes a carbon core guard structure where the exterior guard envelops the central case. By supporting the core at four specific points, Casio has created a unique "floating" effect that efficiently absorbs heavy impacts while maintaining a sleek, three-dimensional aesthetic.

Next-Gen Precision: TOUGH MVT.2

The most significant technological leap in the GWR-B3000 series is the introduction of the TOUGH MVT.2 (Tough Movement 2). This upgraded movement includes highly sensitive disturbance detection capabilities to ensure absolute precision:

• Magnetic Field Detection: If the watch encounters a strong magnetic field, it temporarily pauses hand movement to prevent damage or extreme inaccuracy, automatically snapping the hands back to their correct positions once the interference is gone.

  
  

• Shock Detection: The system automatically recalibrates and corrects hand alignment if displaced by a severe physical impact.

  
  

Eco-Friendly Materials Meet Smart Tech

Casio is taking steps to reduce its environmental footprint by incorporating biomass plastics into the main resin components of the band and center case. The rugged watch face is protected by a spherical, anti-reflective coated sapphire glass crystal, paired with a high-contrast dark black dial engineered with light diffusion technology for maximum legibility in any cockpit.

On the tech side, the watch is powered by the Tough Solar charging system. Timekeeping remains flawless through Multiband 6 radio wave reception and Bluetooth mobile link capabilities. When paired with the "CASIO WATCHES" smartphone app, users can manage automatic time adjustments and accurately log flight data.

Dimensions and Pricing

Despite its heavy-duty features, the new GravityMaster maintains a highly wearable profile. It measures 56.7 × 47.3 × 14.1 mm, weighs in at 102 grams, and features standard 20-bar (200 meters) water resistance.

The series is rolling out to the Japanese market in July 2026. The official pricing (tax included) is as follows, with estimated equivalents based on current exchange rates:

Model	Reference	Price (JPY)	Est. Price (USD)	Est. Price (EUR)
GravityMaster Black	GWR-B3000-1AJF	￥110,000	$680	€595
GravityMaster Blue	GWR-B3000A-2AJF	￥126,500	$782	€684
