Setup

Initial Charging (Tough Solar)

Upon first use or after prolonged storage in darkness, expose the watch face to light for several hours to ensure a full charge. The watch features a solar panel on its dial that converts light into electrical energy. A fully charged battery can power the watch for an extended period, even in complete darkness.

• Place the watch where its face is exposed to bright light (e.g., near a window).
• Avoid placing the watch in direct sunlight for extended periods in extremely hot environments, as this may cause damage.
• Check the battery level indicator (if available on the digital display) to confirm charging progress.

Setting Time and Date

Your watch automatically adjusts the analog hands to match the digital time. Therefore, only the digital time needs to be set manually.

1. In the Timekeeping Mode, press and hold the ADJUST button (top left) until the city code starts flashing on the digital display. This indicates the setting mode.
2. Use the SEARCH button (bottom right) to cycle through different settings (City Code, DST, 12/24-hour format, Seconds, Hour, Minute, Year, Month, Day, Language).
3. Use the LIGHT button (top right) and MODE button (bottom left) to change the flashing setting.
4. Once all settings are configured, press the ADJUST button again to exit the setting mode. The analog hands will automatically adjust to the new digital time.

Maintenance

Cleaning and Care

• Wipe the watch with a soft, dry cloth to remove dirt and moisture.
• For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent. Avoid harsh chemicals.
• Clean the resin band regularly to prevent skin irritation and maintain its appearance.

Water Resistance

The watch is water resistant up to 100 meters (10 BAR). This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water, as well as swimming and snorkeling. Do not operate buttons while the watch is wet or submerged.

Solar Cell Care

To ensure optimal performance of the Tough Solar power system, expose the watch to light regularly. If the watch is stored in darkness for extended periods, the battery may deplete, and functions may cease. The watch has a power-saving function that turns off the digital display when in darkness to conserve power.
