2. Setup
2.1 Initial Charging
Upon first use or after prolonged storage in darkness, your Eco-Drive watch requires an initial charge. Expose the watch dial to a bright light source (natural sunlight is ideal) for several hours. The watch will begin to operate once sufficient charge is accumulated. For a full charge, refer to the charging time guidelines in the full Citizen Eco-Drive manual.
2.2 Setting the Time and Date
The BL9000-08A is a complex timepiece. Accurate setting requires careful attention to the crown and pusher operations. Refer to the detailed instructions below:
- Pull the Crown: Gently pull the crown out to the time-setting position. The second hand may stop.
- Set Time: Rotate the crown to adjust the hour and minute hands to the correct time. Pay attention to AM/PM indication if present.
- Set Date/Calendar: Use the designated pushers (typically located at 2, 4, or 8 o'clock positions) to adjust the perpetual calendar functions, including month, date, and day of the week. Consult the specific markings on your watch for guidance.
- Push the Crown: Once all settings are correct, push the crown back into the normal position to resume timekeeping.
Note: Due to the intricate nature of the perpetual calendar and minute repeater, it is highly recommended to consult the comprehensive Citizen Calibre 9000 series manual for precise setting procedures.
3. Operating Functions
3.1 Using the Minute Repeater
The minute repeater function allows the watch to audibly chime the current time. This is typically activated by pressing a specific pusher on the watch case (often at the 8 or 10 o'clock position). The chimes will indicate hours, quarter hours, and minutes. Listen carefully to distinguish the different tones.
3.2 Perpetual Calendar
The perpetual calendar automatically adjusts for the varying lengths of months and leap years. Once correctly set, it will display the accurate date, day, and month without manual adjustment until the year 2100. The subdials on the watch face indicate these calendar functions.
3.3 Chronograph Function
To operate the chronograph (stopwatch):
- Start: Press the upper pusher (e.g., at 2 o'clock) to start the chronograph.
- Stop: Press the upper pusher again to stop the chronograph.
- Reset: Press the lower pusher (e.g., at 4 o'clock) to reset the chronograph hands to zero.
4. Maintenance
4.1 Cleaning Your Watch
To maintain the appearance of your watch, wipe the case and crystal with a soft, dry cloth. For the leather strap, avoid excessive moisture and harsh chemicals. If the watch becomes soiled, a slightly damp cloth can be used, followed by immediate drying.
4.2 Water Resistance Guidelines
The Citizen BL9000-08A is designed with a water resistance rating suitable for minor exposure to water. This means you may wear the watch while washing your face or in light rain. It is not designed for use underwater, swimming, showering, or any activity involving full submersion. Exposure to steam or hot water should also be avoided as it can compromise the watch's seals.
4.3 Eco-Drive Power Cell Care
To ensure optimal performance of your Eco-Drive watch, regularly expose it to light. Avoid prolonged storage in dark places, which can deplete the power reserve. If the watch stops, expose it to bright light for several hours to recharge. The power reserve indicator (if present) can help monitor the charge level.
