2. Setup

2.1 Initial Charging

Before initial use, expose the watch face to light for several hours to ensure the built-in rechargeable battery is adequately charged. The Tough Solar system converts both sunlight and artificial light into electrical energy, which is stored in the battery. Regular exposure to light is essential for optimal performance and longevity of the watch.

2.2 Time Synchronization (Multi Band 6)

The watch automatically receives time calibration signals from six global transmission stations to maintain accurate time. For best reception, place the watch near a window at night. The watch will attempt to receive the signal automatically.

The Multi Band 6 system covers major cities in North America, Europe, Japan, and China. Ensure your watch is set to the correct home city for proper signal reception.

3. Operating Instructions

The watch features multiple modes accessible via the side buttons. Refer to the specific button functions for each operation.

3.1 Timekeeping Mode

This is the default mode, displaying the current time and date. The analog hands show the hour and minute, while the digital display shows the date and day of the week. The watch automatically adjusts for daylight saving time if enabled and signal reception is successful.

3.2 Stopwatch Function

The stopwatch measures elapsed time with 1/100-second accuracy, up to 60 minutes. To activate, switch to stopwatch mode using the mode button. Press the start/stop button to begin and end timing, and the reset button to clear the measurement.

3.3 Countdown Timer

The countdown timer can be set for durations from 1 minute to 100 minutes, with a measuring unit of 1 second. It is useful for timing specific activities. An alarm sounds when the countdown reaches zero.

3.4 Daily Alarms

The watch includes multiple daily alarms. Each alarm can be set to sound at a specific time. There is also an hourly time signal option that beeps every hour on the hour.

3.5 LED Light (Afterglow Function)

Press the light button to illuminate the watch face for easy reading in dark conditions. The afterglow function keeps the light on for a short period after the button is released.

3.6 Multi-language Display and 12/24 Hour Format

The digital display can show the day of the week in English, Japanese, Chinese, Spanish, or German. The time display can also be switched between 12-hour and 24-hour formats.

4. Maintenance

4.1 Water Resistance

The watch is water-resistant to 5 bar. This means it can withstand splashes, rain, and brief immersion in water, such as during hand washing. It is not suitable for swimming, diving, or showering with hot water.

4.2 Solar Charging Care

To maintain optimal battery charge, expose the watch to light regularly. Avoid prolonged storage in dark places, as this can lead to the battery level dropping and functions becoming disabled. If the battery level is low, expose the watch to bright light until the indicator shows a sufficient charge.

4.3 Cleaning

Wipe the watch and band with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, use a slightly damp cloth and then dry thoroughly. Avoid using chemical cleaners or solvents, as these can damage the watch's finish.

5. Troubleshooting

5.1 Time Synchronization Issues

If the watch fails to synchronize with the time calibration signal:

• Ensure the watch is placed near a window or in an open area, away from electronic devices that may cause interference.
• Verify that the home city setting on the watch is correct for your region.
• Check the signal reception status (often indicated on the digital display).

5.2 Low Battery Indicator

If the battery indicator shows a low charge level, expose the watch to bright light (e.g., sunlight) for an extended period. The watch may enter a power-saving mode or stop functioning if the battery level becomes critically low.

5.3 Incorrect Time/Date Display

If the time or date is incorrect despite successful signal reception, perform a manual time adjustment or reset the watch to its factory default settings (refer to the full user manual for detailed steps).
