About the Watch in short. If you are a fan of surfing and an active lifestyle, then the GAX-100 will become your indispensable assistant. A model from the G-Lide division [in this case, the summer version], which means there is everything for water sports here – an ebb / flow tide sensor in the form of additional. a window, displaying the phases of the moon at every point on the globe, and even a thermometer to measure air temperature. Thanks to the large hands and hour markers, you can see the time from any angle. The case shape is borrowed from models from the GA series, but this is their only similarity – the design of the GAX dial is absolutely unique. The case is stable in the influence of magnetic fields, well, the standard digital capabilities by itself – a stopwatch, timer, world clock and alarms.

*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.

Official Marketing Focus from Casio
G-SHOCK G-LIDE has long been a favorite choice among the world’s top surfers and street sports athletes, and these new additions for 2016 promise to maintain that tradition.
The new GAX-100 combination model provides the best of both analog and digital formats. Large hour markers, hour hand, and minute hand contribute to easy reading. The arrow shaped minute hand and the contrasting color of the analog hands provide at-a-glance readings even while paddling or waiting the next wave. Surfing-oriented functions include Tide Graph, Moon Data, and temperature measurement. Just about everything about this watch is designed to support activities on the summer seas. An analog Tide Graph feature provides an intuitive readout of current time conditions when you need it.
