G-Shock GRAVITYMASTER, Carbon Core Guard Monocoque ‘GWRB1000-1A1’

From GRAVITYMASTER, the tough watch designed for the severe environments faced by pilots, come new GWR-B1000 Series models with Carbon Core Guard structures. The case and back cover are integrated into a carbon monocoque configuration, and the carbon face incorporates CASIO original solar technology that maximizes power generation using the light that enters through the digital dial surfaces. G-SHOCK red brand coloring is embedded in the carbon bezel layers and around the dials. All of this adds up to a new G-SHOCK design that is tougher and more stylish than ever. The base model is the GWR-B1000 whose generous use of titanium and other highfunction materials creates a timepiece of outstanding toughness, light weight, and rust resistance. Automatic time adjustment is performed using either Bluetooth® or a time signal, which helps to ensure accurate timekeeping while flying on a mission”

Designed to be the toughest, lightest model in the GRAVITYMASTER Series.

New shock resistant construction
Carbon Core Guard
A new shock resistant Carbon Core Guard integrates the case and back cover into a monocoque case that protects the module. An external structure that capitalizes on the high strength and lightweight characteristics of the material used dramatically improves toughness while also enabling a weight of only 72 grams, making this the lightest model in the GRAVITYMASTER Series.

SMARTPHONE LINK

Links with a smartphone for more accurate timekeeping and access to a host of mobile link functions.

 

TRIPLE G RESIST

(Shock resistant, Centrifugal force resistant, Vibration resistant)

Designed to withstand the shock of three forces: gravitational dropping forces, centrifugal gravitational force, and vibration. Unmatched toughness only from G-SHOCK

 

TOUGH SOLAR

CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power.

 

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.

  • Atomic Timekeeping

    Shows accurate time by receiving radio signals of standard time information. JJY= Corresponds to both of Japanese standard waves JJY (40kHZ/60kHZ); WWVB= Corresponds to the USA standard wave WWVB (60kHz); MSF/DCF77= Corresponds to UK and Germany standard waves MSF/DCF77 (60kHz/77.5kHz); BPC= Corresponds to Chinese standard wave BPC (68.5kHz)

  • Bluetooth®

    Link wirelessly to a smartphone using Bluetooth® SMART

  • Solar Power

    A solar cell provides power for operation

  • Auto-Hand Location

    Using an LED, the positions of the hour, minute and second hands are checked at the 55'00" of every hour to ensure correct hand positioning. If the hand time does not coincide with the counter within the IC, the movement corrects the hand position automatically

  • LED Light (Super Illuminator)

    A light emitting diode is used to illuminate the face/display. Super Illuminator uses high-brightness LED for easier reading

  • Dual Time

    Simultaneous display of the current time in two different time zones

  • Beeper Alarm

    Beeper tone alarm sounds at the time you set

  • Stopwatch (24HR)

    Accurate measurement of elapsed time with the touch of a button. The fraction indicates the unit of measurement, while the time figure indicates the maximum time measurement

  • Timer (24H)

    Counts down from a start time specified by you. The value indicates the number of timers available, while the time figure indicates the maximum starting time. “REPEAT” indicates Auto Repeat, which automatically restarts timing at the end of each countdown

  • Full Auto-Calendar

    Allowances are made automatically for months of different lengths, including leap year

  • Battery Level Indicator

    Indicator shows the current battery level

  • Triple G-Shock Resistant

    Designed to withstand the shock of three forces: gravitational dropping force, centrifugal gravitational force and vibration

  • Rust Resistant

    All external metal parts exposed to the air are highly resistant to rust

  • Neobrite

    A luminous coating provides long-term illumination in the dark after only short exposure to light

  • Water Resistant (20 BAR)

    The “BAR” value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked “200m” have the same water resistance as 20 BAR watches

  • Sapphire Glass

    Glass is made using artificial sapphires with scratch-resistant hardness second only to diamonds and high transparency

  • Spherical Glass

    The surface of the glass is rounded
