For this new GRAVITYMASTER, Casio has developed a carbon core guard structure, a new kind of shock-resistant structure. In addition, the pursuit of extreme toughness has led to the use of a carbon monocoque case, which unifies the case and back cover for a further improved airtight construction.

Through the use of highly functional materials, such as the carbon on the bezel and band and titanium for the push buttons and button pipes, the structure of the watch is made stronger, more lightweight, and rust-resistant. GWR-B1000 is equipped with Bluetooth® and radio-controlled timekeeping systems to achieve the accuracy required for professional flight missions.


Carbon monocoque case
The case and back cover are part of a unified construction that ensures that the watch is both strong and airtight. In addition, the use of carbon materials grants greater freedom of design while increasing shock resistance.

Titanium materials are used for the metal parts that are exposed to outside air, making them lightweight, strong, and resistant to rust. The tough structure of the watch protects it from three types of gravitational acceleration: impact forces, centrifugal forces, and vibrations.

Carbon fibre has ten times the strength of iron at one-fourth its weight, and acquires excellent shock absorption. Titanium is about half the relative density of iron, but rivals steel in strength. By making widespread use of these two highly functional materials, GWR-B1000 achieves a weight of 72 g, the lightest for GRAVITYMASTER, while also maintaining the greatest shock resistance in the series. The watch is comfortable to wear for long periods, making it pilot-friendly.

Carbon core guard structure
A new shock-resistant carbon core guard structure integrates the case and case back into a monocoque case that protects the module. An external structure capitalizes on its toughness and lightness.

Bezel with 52 layers of carbon sheeting
The bezel is made of carbon materials as well, making it highly durable and resistant to damage. The layered carbon bezel is designed to keep flexibility and to absorb shock. It is achieved by making a clearance between the case and the bezel.

Shock-resistant button
The new carbon case helps to develop a new structure of button. This also enables removing the button guards from the exterior.

Carbon dial (GWR-B1000X)
A carbon fibre material used in recent aircraft construction has been adopted for the dial.

Stopwatch with flyback function
The button at 2 o’clock can be used to start a stopwatch operation while in the stopwatch mode. During a stopwatch operation, a single press of the button at 4 o’clock instantly stops the current operation, resets the stopwatch, and starts a new lap time. This flyback feature avoids time lost to button operations.

In-dial solar panel
Further improvements in the shadow dispersing solar panel by optimizing solar cell shapes to improve power generation efficiency and make it possible to generate sufficient power using only the light received through the dial areas of the face. This eliminates the need to limit the transmittance of the face, which greatly enhances face design possibilities.

Super Illuminator (high-brightness LED)
The LED illuminates the dial to ensure visibility in the dark.

Sapphire crystal with non-reflective coating
To ensure high readability, non-reflective coating is applied on the scratch-resistant sapphire crystal.

Carbon fibre insert band
Carbon fibre of outstanding tensile strength is moulded into urethane resin with high cutting/tear resistance.
