Casio G-Shock GA-140 Watches

About the Watch in short. GA-140 – these are shocks in the classical sense. A round case and dial, symmetrical overflows over the glass to protect it, and a strap and bends [to absorb shock load] – this form factor is very recognizable in Jishokov circles. Fundamental changes affected only the design of the dial, which has now become more modern and fashionable. The functionality has not changed much – the exact same [measurement step 1/1000 second] stopwatch for 100 hours, a timer with auto-repeat for 24 hours, five alarms [one with the “snooze” function], world time, calendar and time at 12/24 hourly format. At night, the display illuminates the LED, with auto-triggering when you turn your hand. The battery is designed for 2 years of operation, water resistance at the level of 200 meters – we dive without problems.

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.

Official Marketing Focus from Casio

G-SHOCK, the watch that has been setting the standard for timekeeping toughness since 1983, announces a new collection of analog-digital combination models based on the popular GA Series, but with new face and hand designs.
These new models inherit the big-case designs from the classic GA-100. A motif that resembles a 90’s stereo component device or portable music player is updated to a modern refined look while maintaining G-SHOCK level toughness.
