Initial Setup
Charging the Watch
Your Eco-Drive watch is powered by light. To ensure proper operation, expose the watch dial to a light source (natural or artificial) for several hours before initial use. Avoid placing the watch in direct sunlight for extended periods in hot environments to prevent overheating. A full charge can provide approximately 6 months of operation in darkness.

Setting the Time and Date (Radio Control)
This watch automatically synchronizes with atomic time signals. For manual synchronization or initial setup, ensure the watch is in an open area, away from electronic interference, for optimal signal reception.
- Mode Selection: Rotate the crown to select the "TIME" mode.
- Signal Reception: Press and hold the appropriate button (e.g., top right pusher) to initiate manual signal reception. The second hand will indicate reception status.
- Time Zone Adjustment: If necessary, adjust your home city/time zone according to the detailed instructions in the full product manual.
Operating the Watch
Using the Stopwatch
The integrated stopwatch function allows for precise time measurement up to a certain duration, typically 24 hours.
- Activate Stopwatch Mode: Rotate the crown to the "CHR" (Chronograph) mode.
- Start/Stop: Press the top right pusher to start and stop the stopwatch.
- Reset: Press the bottom right pusher to reset the stopwatch to zero.
Setting Alarms
The watch features multiple alarms (AL-1, AL-2) that can be set for daily reminders.
- Select Alarm Mode: Rotate the crown to "AL-1" or "AL-2" mode.
- Set Alarm Time: Use the pushers to adjust the hour and minute settings for the selected alarm.
- Activate/Deactivate: Press a designated button (e.g., bottom right pusher) to toggle the alarm on or off.
World Time Function
The watch can display time for various world cities, making it convenient for travelers.
- Enter World Time Mode: Rotate the crown to "W.T.C." (World Time City) mode.
- Select City: Use the pushers to cycle through available city codes. The digital display will show the corresponding time for the selected city.
Maintenance
Charging Guidelines
To maintain optimal performance and power reserve, ensure the watch receives adequate light exposure daily. If stored in darkness for extended periods, the power reserve may deplete, requiring a full recharge. Avoid extreme temperatures during charging.
Water Resistance
This watch is water resistant to 200 meters (20 ATM). It is suitable for professional marine activity and serious surface water sports, but it is not designed for scuba diving. Always ensure the crown is pushed in completely before exposing the watch to water. Do not operate buttons or the crown underwater.
Cleaning
Clean the watch case and bracelet regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by thorough drying. Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish or seals.

Troubleshooting
- Watch not running or stopping: Ensure the watch is fully charged by exposing it to bright light for an adequate period. If the issue persists after charging, contact customer support.
- Incorrect Time: Perform a manual radio signal reception. Verify your home city/time zone setting is correct. If the watch is unable to receive a signal, manual time setting may be required.
- Digital display not visible: Check if the analog hands are obstructing the digital display. Some models allow for hand retraction to clear the view. Refer to the full manual for specific instructions on this feature.
- Buttons or crown are stiff: Clean around the buttons and crown to remove any accumulated dirt or debris. Avoid forcing them.
