Casio G-Shock GWR-B1000 Watch

About the Watch in short. The flagship model from the Gravitymaster line for pilots. The first ever G-Shock with a completely one-piece “monocoque” body made of carbon fiber. The case back, in the usual sense, is missing – the case is monolithic, and due to this, even greater impact resistance and reliability of the case are achieved. A completely new protective concept of the case – Carbon Core Guard is the presence of a special carbon body part that surrounds the watch module and protects them from any mechanical influences. Thanks to this, the GWR-B1000 is not only stronger than its counterparts, but also much lighter due to the use of carbon. Laminated carbon bezel consists of 52 separate layers, the button mechanism is isolated from the environment. The functionality of the series is also elite – solar power, multiband time synchronization, “pairing” with a smartphone via Bluetooth protocol [for auto-adjusting time and clock settings], 24-hour stopwatch with Fly Back function [quick zeroing], timer, one alarm clock, world time , well, of course, the proprietary “aviator” protection Triple G Resist [shock, centrifugal force and vibration]. Tough Movement [hard turn of the hands and their correction] and Smart Access [smart crown].

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

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.

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

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

Shock resistant button. A cleaner design that removes the button guard was achieved through improved case strength and the newly developed structure.

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.

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.

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.

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

G-SHOCK CONNECTED App. Connection with a phone requires installation of the G-SHOCK CONNECTED App on the phone.

Smart Access. This ground-breaking CASIO system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown.

Official Marketing Focus from Casio

From GRAVITYMASTER, the tough watch designed for the severe environments faced by pilots, comes a new timepiece that delivers an even higher level of toughness through the use of the same carbon and titanium materials found on modern aircraft.
A new shock resistant Carbon Core Guard structure integrates the case and back cover into a single carbon Monocoque unit that protects the module from external shock and makes it possible to eliminate carbon guard parts from the buttons on the sides of the case.
The use of carbon material for the bezel and band, and titanium alloy for buttons, button pipes, and components results in a watch that is both structurally tough, lightweight, and resistant to rust.
Automatic time adjustment is performed using either Bluetooth® or a time signal, which helps to ensure accurate timekeeping while flying on a mission.
