GWRB1000
All new Gravitymaster with Carbon Core Guard.
The third material has the lightness of resin and a strength exceeding that of metal.
Beginning from the newly developed carbon monocoque case, the watch makes use of high-performance carbon materials that exhibit strength and lightness in countless locations. The design achieves the shock resistance required of a pilot’s watch, while at the same time weighing just 72 g,
the lightest watch in the GRAVITYMASTER lineup.

Carbon monocoque case
This new shock resistant structure protects modules with a carbon fiber reinforced resin case.

Intricately laminated bezel with 52 layers of carbon sheeting

Carbon fibre insert band
*Constructed with Toray’s TORAYCA® carbon fiber.


Design & Technology

Rust-resistant
Titanium materials are used for the metal parts that are exposed to outside air, making them lightweight, strong, and resistant to rust.

TRIPLE G RESIST
Shock, centrifugal force, and vibration-resistant structure.
* Image shows GPW-2000-1A.

Large front button
A large button placed at the 6 o’clock position on the case activates the light and accentuates the rugged design.

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

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.

Stopwatch with 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.

Bluetooth® + Radio-controlled, solar-powered timekeeping
Time correction is conducted by either Bluetooth® communications or standard time radio wave (Multi Band 6*), depending on the circumstances. Reception of the most recent time zone and Daylight Saving Time information assures that the correct time is displayed at all times.
*Multi-Band 6 not available in NZ.

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