Casio G-Shock AWG-M100 Watches

About the Watch in short. One of the smallest and most compact G-Shocks at the moment. Laconic an-DJ dial with large hands and digital windows contributes to good readability and convenient display of data. The case design is made with notes of “militarism” – dark tones, angular hour markers, “pin” inserts on the case and strap will appeal to the military. Due to the small thickness and width of the body, the AWG-M100 is suitable even for the smallest wrist and will not “stick out” on it, like other shocks. The watch has a fairly advanced filling – solar power and radio time synchronization. The solar battery will allow you to forget about the need to replace the battery after 2-3 years, and the time is automatically synchronized by radio waves with towers located around the world. The basic functionality is also present – a stopwatch, timer, world clock, alarm clock and display backlight.

Enjoy Japanese approaches to Tough and Functional Watches!

*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.
