Setup

1. Initial Charge

Your watch is powered by a solar cell. Before initial use, expose the watch face to bright light for several hours to ensure it is sufficiently charged. Avoid covering the watch face during charging.

2. Radio Wave Reception (Automatic Time Adjustment)

The watch automatically receives time calibration signals up to six times a day (five times for China signals) to maintain accurate time. For optimal reception, place the watch near a window at night. The watch supports signals from Japan, North America, Europe, and China.

3. Manual Time Adjustment / World Time City Setting

If automatic reception is not possible or you are in an area not covered by radio signals, you can manually set the time. The watch features a dual dial world time function, allowing you to display the time for two different cities simultaneously. Use the crown and buttons to select your home city and desired world time city. Refer to the detailed manual for specific button operations.

4. Automatic Hand Position Correction

The watch is equipped with an automatic hand position correction function that periodically checks and corrects the hand alignment to ensure accurate time display.

Operating

Basic Timekeeping

The watch displays hours, minutes, and seconds. The date and day of the week are also shown. The full auto-calendar adjusts automatically for different month lengths and leap years.

World Time Function

The dual dial world time feature allows you to view the current time in 29 cities (29 time zones) plus Coordinated Universal Time (UTC). Summer time settings are automatically applied.

Stopwatch

The watch includes a 1/20-second stopwatch with a 60-minute measuring capacity.

Power Saving Function

To conserve power, the watch enters a power-saving mode when left in the dark for a certain period, stopping the hands. It resumes normal operation when exposed to light again.

Maintenance

Water Resistance (10 BAR)

Your watch is water-resistant up to 10 BAR. This means it is suitable for swimming and snorkeling. Do not operate buttons or the crown while the watch is wet or submerged. After exposure to saltwater, rinse the watch thoroughly with fresh water and wipe it dry.

Cleaning

Wipe the watch case and band with a soft, dry cloth to remove dirt and moisture. For metal bands, use a soft brush with mild soapy water to clean between links, then rinse thoroughly and dry. Avoid using harsh chemicals or abrasive materials.

Sapphire Glass Care

The watch features sapphire glass with a dual-sided anti-reflective coating, providing high scratch resistance and clarity. While highly durable, avoid strong impacts. Clean with a soft, lint-free cloth.

Solar Charging

Regularly expose the watch to light to ensure continuous operation. If the battery charge level becomes low, a battery charge warning function will activate. The watch can operate for approximately 5 months on a full charge with normal use, and approximately 22 months in power-saving mode without further light exposure.

Troubleshooting

Time is Incorrect

• Radio Wave Reception: Ensure the watch is placed in a location with good signal reception, especially overnight. Avoid areas with strong magnetic fields or electronic interference.
• Manual Adjustment: If radio reception is consistently poor, manually adjust the time and date as described in the 'Setup' section.
• Hand Alignment: If hands are misaligned, perform the automatic hand position correction procedure.

Watch Not Operating / Hands Stopped

• Insufficient Charge: Expose the watch face to bright light for an extended period to charge the solar battery. The watch may be in power-saving mode.
• Battery Warning: If the battery charge warning is active, charge the watch immediately.
