Important Notes

The watch includes one CR2 battery, which is pre-installed and supported by solar charging for extended life. While not currently discontinued by the manufacturer, availability may vary by region. A manufacturer’s warranty is available and can be requested directly through Casio’s customer service. The product dimensions and lightweight design (0.35 ounces) contribute to comfortable all-day wear. Always ensure proper care to maintain water resistance and functionality, especially after exposure to saltwater or heavy impacts. For optimal atomic time synchronization, periodic exposure to open sky is recommended to receive radio signals.
