Comming soon!

Basel, March 20, 2019 — Casio Computer Co., Ltd., announced today the release of a new
edition to the aviation concept GRAVITYMASTER series, part of the G-SHOCK brand of shock-
resistant watches. The GWR-B1000X is a limited-edition model featuring accents of the G-
SHOCK red brand colour.
Like its base model GWR-B1000, the new GWR-B1000X is equipped with a new Carbon Core
Guard structure for shock resistance, but this special model features accents of the red brand
colour of G-SHOCK throughout the watch—from the inner laminate of the carbon bezel to the in-
dial ring and G-SHOCK logo. Also carried over from the base model GWR-B1000 is the use of
carbon composite material in the case and a carbon-fibre* insert band with excellent tensile
strength to withstand use in the harshest conditions. These carbon materials give the watch
shock resistance, rigidity, and resistance to degradation—the same properties that qualify carbon
materials for use in aircraft fuselage parts. The GWR-B1000X also employs carbon composite
material in the dial.
The base model GWR-B1000 uses a carbon monocoque case that seamlessly integrates the
case and case back. The result is a watch that boasts high strength while weighing less than any
previous GRAVITYMASTER series watch. The GWR-B1000X also features TRIPLE G RESIST
technology to withstand shock, centrifugal force, and vibration, and all of its externally exposed
metal parts are made from rust-resistant titanium.
