2. Setup
2.1 Initial Charging
Your SEIKO Coutura watch is powered by light energy. Before initial use, ensure the watch is sufficiently charged by exposing the dial to bright light (natural sunlight is ideal) for several hours. A full charge provides approximately 6 months of power reserve.
2.2 Time and Date Setting
Refer to the detailed instructions in the full manufacturer's guide for precise time, date, and perpetual calendar settings. The watch features a perpetual calendar that automatically adjusts for odd and even months, including leap years, until February 28, 2100. The day, month, and leap year indicators are displayed on the dial.

3. Operating the Watch
3.1 Chronograph Function
The watch is equipped with a chronograph for measuring elapsed time. Typically, one pusher starts and stops the chronograph, while another resets it. Consult the full manual for specific button assignments and operation modes (e.g., split time, lap time).
3.2 Alarm Function
The alarm can be set using the dedicated sub-dial. Follow the instructions in the comprehensive guide to set and activate the alarm. Ensure the alarm is set to the correct 24-hour format if applicable.
3.3 Water Resistance
This watch is water-resistant up to 100 meters (10 bar), making it suitable for short periods of recreational swimming. It is not recommended for diving or prolonged water activities. Always ensure the crown is pushed in completely before exposing the watch to water.

4. Maintenance
4.1 Cleaning
Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For stainless steel components, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or abrasive materials.
4.2 Sapphire Crystal Care
The watch features a scratch-resistant sapphire crystal. While highly durable, it is not entirely impervious to damage. Avoid impacts and contact with extremely hard surfaces to prevent scratches or cracks.
4.3 Power Reserve
To maintain the 6-month power reserve, ensure the watch is regularly exposed to light. If stored in darkness for extended periods, it may require recharging. If the watch stops, expose it to bright light for several hours to reactivate it.
5. Troubleshooting
5.1 Watch Not Running
If the watch is not running, ensure it has been sufficiently charged by exposing it to bright light. If the issue persists after charging, consult the full manual or contact customer support.
5.2 Incorrect Time/Date
If the time or date is incorrect, refer to the 'Time and Date Setting' section in the full manual to reset the watch. For perpetual calendar issues, ensure the watch is fully charged and has been set according to the instructions.
5.3 Water Intrusion
If moisture appears inside the watch, immediately take it to an authorized service center. Do not attempt to open the watch yourself, as this will void the warranty.
