About the Watch in short. This new model is the first in the GRAVITYMASTER lineup to be equipped with digital compass capabilities, creating a watch that is perfectly matched to the needs of the modern aviator, both in terms of function and appearance. Pressing the 9 o’clock button in any mode immediately goes to the Digital Compass Mode, and a button at 8 o’clock returns to the mode you were in before the Digital Compass Mode. Continual direction readings can be taken for 20 seconds, during which the second hand points to north, a literal direction indicator is displayed in the upper display, and a direction angle value is displayed in the lower display.

What we like in GA-1000 *comments by experts with 10 years experience in writing about Casio watches
— 200-meter water resistance
(good for swimming but not for deep diving)
— Digital compass (measures and displays direction as one of 16 points)
— Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
— Neon Illuminator (Illuminating the display causes the face, and hour and minute hands to glow with neon color, which looks great late on a dark outdoor night)

Enjoy Japanese Unique Features in GA-1000!

*some images are about G-Shock 5000/5600 cases, but the technology, approaches, concepts and philosophy remains the same for the whole G-Shock Model Range

Hollow case structure. Based on a realization that “shocks are not transmitted inside a bouncing rubber ball,” the structure was designed to let the module float inside the case, relieving shocks transmitted from outside. Today, the module’s shock resistance is realized through further technical innovations. But the revolutionary tough structure that gave G-SHOCK its origin began here.

All-directional covering. If the watch is dropped, the protruding bezel fully enclosing it absorbs the shock, protecting the buttons directly connected to the module and alleviating shocks from all directions. The bezel also guards the surface of the crystal. The band is curved stiffly at the point of connection with the case, moreover, enabling it to serve as a shock absorber and prevent direct shocks to the back of the case.

Protective cushioning of key parts. The crystal oscillator and other critical parts inside the module are guarded individually by cushioning material. Any strong shock to the watch causes immediate distortion of the cushioning inside the module, preventing contact failure and malfunction.

Japan Quality. Constructed with genuine quality, CASIO products provide truly practicable applications in which functionality and beauty combine. The leading-edge LSI technologies and skilled craftsmanship that give life to CASIO watches exemplify the quality Japan boasts in the world marketplace.
For CASIO, “faith in manufacturing” refers to an inexorable advancement of digital technologies and an uncompromising commitment to fine craftsmanship. This faith engenders unparalleled performance that not only elevates CASIO watches as close as possible to perfection, but that actually changes their wearers’ lifestyles.
