Reinforced waterproofing for daily life: 20BAR

Impact resistant structure resistant to shock and vibration

JIS class 1 magnetic resistance

A large rotary switch allows sensory operation

Auto LED light that lights when you tilt your arm (only when Auto Light is ON)
Product introduction G-SHOCK, which continues to evolve in pursuit of toughness, introduces an additional color model of GA-400 that uses a large rotary switch and realizes sensory operation. G-SHOCK brand color black × red is used as the base color. Although it is a basic color scheme, it has an unprecedented design. By adopting a large rotary switch, operability such as world time city selection and timer setting has been improved. A model that combines practicality with a combination of colors that symbolize brand identity and toughness design.

● Shock-resistant structure

● Anti-magnetic watch (JIS type 1)

● 20 ATM water resistant function

● Needle retraction function (If the needle is difficult to see because it overlaps the liquid crystal display, you can temporarily retract the needle from the top of the liquid crystal display)

● World time: 48 cities (31 time zones, with daylight saving time setting function) + UTC (universal coordinated time) time display, UTC direct call function, home time city replacement functionStopwatch (1/100 second, 24 hour total, (With split) Timer (set unit: 1 minute, maximum set: 60 minutes, measured in units of 1 second, elapsed time measurement after time up (60 minutes) included) Time alarm 5 (with only 1 snooze function) Time signal

● Full auto calendar

● 12 / 24-hour display switching

● Operation sound ON / OFF switching function

● LED light (with auto light, afterglow function, afterglow time switching (1.5 seconds / 3 seconds)) Brand introduction New toughness to watch G-SHOCK (G C). It all started with a developer's conviction to create a watch that would not break even if dropped, and a reckless challenge that overturned common sense at the time. Over 200 prototypes have been repeated, and about two years have been spent, and the shock-resistant structure has been completed. It is the birth of technology that plays a central role in toughness. Since then, G-SHOCK has continued to evolve. Structure, material, function. In pursuit of further toughness from all sides.
