Key Features

• Tough Solar Power: Powered by light—natural or artificial—this solar rechargeable battery eliminates the need for frequent battery changes. A full charge provides approximately six months of operation without additional light exposure, supported by a battery power indicator and power-saving mode to extend efficiency.
• Multiband Atomic Timekeeping: Automatically synchronizes with radio signals from calibration stations in the US (WWVB), UK (MSF), Germany (DCF77), Japan (JJY40/JJY60), and China (BPC). This ensures near-perfect accuracy by adjusting for time zone and daylight saving changes, with auto-receive up to six times daily (five in China).
• Shock Resistant Construction: Engineered with G-Shock’s signature shock-absorbing technology, the watch withstands impacts, vibrations, and drops, making it ideal for active lifestyles and demanding work environments.
• Neo-Brite Luminous Hands and Markers: Ensures clear visibility in low-light conditions, allowing for easy time reading at night or in dimly lit spaces without relying solely on the LED light.
• Auto LED Light with Afterglow: Illuminates the dial automatically when the wrist is raised, with a persistent afterglow for continued visibility in dark settings.
• World Time Function: Displays time in 48 cities plus UTC, with city codes and optional daylight saving adjustments—perfect for international travelers or those coordinating across time zones.
• Five Daily Alarms & Hourly Signal: Offers customizable reminders throughout the day, with an hourly chime to keep you on schedule.
• 1/100 Second Stopwatch: Measures elapsed and split times with precision up to 59 minutes, 59.99 seconds, ideal for training, sports, or timed tasks.
• Countdown Timer: Set intervals from 1 second to 100 minutes, useful for workouts, cooking, or timed activities.
• Auto-Calendar: Pre-programmed until the year 2099, eliminating the need to manually adjust for leap years or month lengths.

Important Notes

The G-Shock Unisex Tough Solar (Model: AWG-M100B-1ACR) is not discontinued by the manufacturer and remains in active production. It ships with one included lithium metal battery. For warranty details, customers should refer to the manufacturer’s official support page. While the watch is highly accurate, time calibration depends on signal reception, which may vary by location and environmental conditions. The auto-receive function may be limited in areas with poor radio signal coverage. Regular exposure to light is recommended to maintain optimal battery performance.
