Why Choose Casio G-Shock GAW-100-1AJF?

Radio-Controlled Accuracy

Stay precisely on time—wherever you are. The GAW-100-1AJF automatically synchronizes with atomic time signals broadcast in Japan, the US, UK, Germany, and China. This ensures you're always wearing the exact time, without having to adjust for daylight saving or time zone changes manually.

Tough Solar Technology

No need to worry about battery replacements. With Casio’s Tough Solar system, this watch charges itself using sunlight or even indoor lighting. A single full charge can keep the watch running for months, even in complete darkness. This eco-friendly feature is not only convenient—it’s powerful and efficient.

Rugged G-Shock Durability

True to its G-Shock heritage, the GAW-100-1AJF is built to withstand impact, vibration, and extreme environments. The watch is shock-resistant, 200-meter water-resistant, and protected by a solid resin case. It's designed to survive outdoor adventures, sports activities, and the occasional accidental drop.

Stylish Black & Red Design

The color scheme isn’t just bold—it’s smart. The deep black case and strap provide an elegant yet rugged canvas for the red accent details, giving this model a sporty and modern edge. Whether worn casually or with tactical gear, the GAW-100-1AJF enhances your overall look with confidence.

Dual Display: Analog + Digital

Enjoy the best of both worlds. The analog hands offer classic appeal, while the digital screen delivers quick access to features like world time, stopwatch, countdown timer, and alarms. The layout is clean, intuitive, and easy to read—even in low light thanks to the LED backlight.

How to Use Your GAW-100-1AJF Watch

One of the strengths of this watch is its ease of use, despite its feature-packed nature. Here's how you can make the most of it:

Set It & Forget It with Radio Sync

When you first receive your watch, place it near a window overnight to receive the radio signal. Once synced, it will automatically adjust itself each night, maintaining precise timekeeping without manual input.

Charging Your Watch

Expose the watch face to natural or artificial light daily to keep it charged. Avoid storing it in dark drawers for extended periods. Even under indoor lighting, it will continue to generate power for consistent performance.

Navigating Features

Use the side buttons to toggle between modes such as:

• World Time (keep track of a second time zone)

• Stopwatch (accurate to 1/100th of a second)

• Countdown Timer (great for workouts or cooking)

• 5 Daily Alarms (stay on schedule)

• Battery Indicator (know when to give it some sunlight)

All of this is intuitively accessible without needing to dive deep into complicated menus.

Solar Charging = No Battery Replacement

Thanks to the solar panel embedded in the face, you won’t need to worry about battery swaps. The watch can store power for up to 7 months on a full charge—even if it’s kept in the dark.
