Casio America, Inc., recently announced the GWRB3000 series to the G-SHOCK GRAVITYMASTER line. Featuring three distinct models (GWRB3000, GWRB3000B, and GWRB3000A), the collection draws inspiration from the immense power of jets piercing through the sonic wall, combining aviation-inspired design, advanced construction, and innovative technology to withstand the demanding forces associated with high-speed flight.
Representing a new challenge from G-SHOCK, the GRAVITYMASTER GWRB3000 series features TOUGH MVT 2 (Tough Movement Version 2), which takes signature G-SHOCK durability to the next level. Along with hybrid mount construction, auto-hand home positioning, and solar power, the movement now includes:
- Shock Detection: senses strong impacts and protects against them by correcting the hand position through a full rotation to ensure constant accuracy.
- Magnetic Field Detection: senses strong magnetic interference and pauses hand movement until the interference passes, resuming movement to the current, accurate time.

To achieve its innovative dual hollow structure, G-SHOCK applied topology optimization, a simulation method used to determine ideal structural forms based on stress conditions. By analyzing dropping shocks, centrifugal force, and vibrations, engineers refined the design through repeated simulations to create a structure that combines a resin shock absorber with a metal protection case, delivering enhanced structural integrity while maintaining a lightweight, sophisticated design.
Every element of the new GRAVITYMASTER has been purposefully designed, from its protective construction to its carefully selected materials. The GWRB3000 series features a Carbon Core Guard structure utilizing carbon fiber-reinforced resin to protect the module while delivering enhanced durability and comfort.
The new GRAVITYMASTER features a sapphire crystal with a non-reflective coating to reduce glare and enhance readability across various environments. A super matte dial created through advanced microfabrication technology minimizes light reflection, while the in-dial solar design enables a solid dial surface without compromising power efficiency. The new GRAVITYMASTER also incorporates carbon-neutral bio-based resin components, reflecting G-SHOCK’s continued efforts to integrate more sustainable materials into its designs.
The new GRAVITYMASTER features key G-SHOCK technologies including:
- Shock Resistance
- Triple G Resist (Dropping Shocks, Centrifugal Force, and Vibrations)
- Carbon Core Guard Structure
- Dual Hollow Structure
- Bluetooth Connectivity
- Radio-Controlled Timekeeping
- Tough Solar Power
- Shock Detection
- Magnetic Field Detection
- Sapphire Crystal with Non-Reflective Coating

The GRAVITYMASTER GWRB3000 series is available in three distinct designs: GWRB3000 (Black IP Bezel, USD 880), GWRB3000B (Silver Bezel, USD 1,100), and GWRB3000A (Blue IP Bezel, USD 990). Each model showcases the collection’s aviation-inspired character through its unique bezel finish, advanced engineering, and refined design.
The G-SHOCK GRAVITYMASTER GWRB3000 Series is available today at gshock.com and at the G-SHOCK SoHo Store, as well as through select retailers nationwide.
