Casio G-Shock GW2310-1 Tough Solar Atomic Sport Watch

Casio Men's G-Shock Solar Atomic Watch is a solar-powered sports watch with EL backlight. It features a world time function with 31 time zones and shock-resistance technology. The watch can be tilted to more than 40 degrees to activate the illumination. It has a Japanese quartz movement with digital displays and a resin band with buckle. Other features include a stopwatch, countdown timer, five alarms, atomic time-keeping with built-in antenna, and 12- and 24-hour formats. The watch is water resistant to 200 m (660 ft).

G-Shock was born from a developer's dream of creating a watch that never breaks. It was designed with a "Triple 10" development concept, aiming for 10-meter free-fall endurance, 10-bar water resistance, and a 10-year battery life. The shock resistant structure was realized through innovative breakthroughs, overturning conventional thinking about watches.

The Casio Men's G-Shock Solar Atomic Watch combines innovative technology with classic sport styling. It has a black resin bezel with helpful text for easy programming. The solar-powered battery can operate for up to 10 months on a full charge. The watch has a bright EL backlight that turns on with wrist movement. It is shock resistant and water resistant up to 660 feet (200 meters). It can automatically receive official atomic time through a built-in antenna.

To operate the auto EL function, the G-shock button should be pressed and held for a few seconds. The auto light switch must be turned on for it to operate. Troubleshooting instructions are available in the manual.

Casio entered the wristwatch market in November 1974, and today is known for solar-powered radio-controlled watches and Bluetooth watches that sync to the user's cell phone to automatically update the time. Casio is at the forefront of developing cutting-edge timepieces that lead the market.
