Multiband 6 is Casio’s radio-controlled time-syncing technology. These watches feature a built-in, high-sensitivity miniature antenna that automatically receives atomic time signals from up to six global transmitters, ensuring accurate and consistent timekeeping.

The Six Transmitters Covered:

1. Japan – JJY Fukushima (40 kHz) and JJY Haganeyama (60 kHz)

2. North America – WWVB (Fort Collins, Colorado)

3. UK – Anthorn Europa

4. Germany – Mainflingen European

5. China – BPC (Shangqiu)

This setup enhances precision and offers automatic night synchronization (up to six attempts) with low power consumption, thanks to the robust shock-resistant antenna design.
