TOUGHNESS TECHNOLOGY
Born from the breakthrough idea of a hollow structure
The case employs a hollow structure which “floats” the module and protects it from shocks. With a full urethane bezel, cushioning material, and other shock-resistant technologies exclusive to G-Shock, the body and module interior receive all-directional enclosure that raises toughness to the highest levels.

TRIPLE G RESIST
Centrifugal, gravity- and vibration- resistant structure
The G-SHOCK Gravitymaster’s centrifugal gravity resistance specifications significantly surpass 15G, the maximum level of cockpit instruments. aGEL® insulates the module and resists vibration frequencies of up to 1000Hz and 20G acceleration. Persistently advancing its evolution, the proprietary G-SHOCK structure achieves an optimal balance and stable hand movement, even under pressure from powerful gravitational forces and violent vibrations.

SHOCK-RESISTANT STRUCTURE
All-directional guard hollow case structure
The protruding configuration adopted for the watch case and bezel protects against direct shocks, with key parts inside the module individually protected with cushioning material to prevent errors in operation or damage if the watch receives a shock. The sections where the band and the case are joined are fixed in a curved shape that enables the band itself to act as a shock absorber, thus guarding even the back of the case from direct shocks.

GPS HYBRID WAVE CEPTOR
GPS satellite + Terrestrial Radio Wave Reception
The two mutually complementary systems, GPS satellite signal reception and terrestrial (Multi Band 6) time-calibration signal reception provides prompt analysis of current time and Daylight Saving Time data to display the correct time all the time, anywhere in the world. A shock-resistant miniature antenna achieves high-sensitivity reception of time reception, tough enough for use during vigorous activities while realising stable, reliable radio wave reception from all six transmission stations across the world.

SMART ACCESS
Proprietary CASIO system for analogue movements
Combining multiple motors with an electronic crown structure for joint operation of various functions such as the World Time city selection, alarm setting, temperature measurement, 1/20-second stopwatch with fly-back, the Smart Access responds to even a pilots’ requirement for both multi-functionality and operability. Mistaken operations are prevented with a quick-lock function that facilitates easy locking or releasing with a 60° click rotation.
