Setup Instructions

1. Initial Charging (Eco-Drive)

Before initial use, ensure your watch is fully charged. Expose the watch dial to a bright light source (natural sunlight is ideal) for several hours. The power reserve indicator will show the charge level. Avoid placing the watch in direct sunlight for extended periods in extremely hot environments to prevent overheating.

2. Atomic Timekeeping Synchronization

Your Navihawk A-T watch automatically receives time signals from atomic clocks to maintain precise time. For optimal reception, place the watch near a window overnight. If automatic reception is unsuccessful, manual reception can be initiated:

  1. Refer to the detailed instructions in the full Citizen user manual for your specific movement (H804).
  2. Typically, this involves pulling the crown out to a specific position and pressing a pusher to initiate signal reception.
  3. Ensure the watch is in an area with minimal interference and good signal strength.

3. Setting Time and Date Manually (if needed)

While atomic timekeeping is automatic, you may need to manually set the time zone or adjust for daylight saving time. Consult the comprehensive manual for your watch's specific caliber (H804) for detailed instructions on crown and pusher operations for manual adjustments.

4. Bracelet Adjustment

For proper fit and comfort, the stainless steel bracelet may need adjustment. It is recommended to have this procedure performed by a qualified jeweler or Citizen service center to prevent damage to the bracelet or watch.

Operating Instructions

1. Using the Chronograph

The chronograph function allows for precise timing of events:

  • Start: Press the upper right pusher to start the chronograph.
  • Stop: Press the upper right pusher again to stop the chronograph.
  • Reset: With the chronograph stopped, press the lower right pusher to reset it to zero.
  • Split Time: Refer to the full manual for advanced chronograph functions like split time measurement.

2. 12/24-Hour Time Display

Your watch can display time in either 12-hour or 24-hour format. The method for switching between these modes varies by specific movement. Consult your detailed user manual for instructions on how to toggle this setting using the crown and/or pushers.

3. World Time Function

The Navihawk A-T allows you to easily switch between different time zones. To utilize this feature, typically you will rotate the crown or use a specific pusher combination to select the desired city code or time zone. The watch will then adjust the time accordingly. Refer to your specific model's manual for the exact procedure.

Maintenance

1. Cleaning Your Watch

Regular cleaning helps maintain the appearance and function of your watch:

  • Wipe the case and bracelet with a soft, dry cloth.
  • For stainless steel, a slightly damp cloth can be used, followed by drying thoroughly.
  • Avoid using harsh chemicals, solvents, or abrasive cleaners.

2. Water Resistance

This watch is rated for 20 BAR (200 meters) water resistance. This means it is suitable for swimming, showering, and snorkeling. However, ensure the crown is pushed in completely before exposing the watch to water. Do not operate the crown or pushers while the watch is wet or submerged.

3. Eco-Drive Care

To ensure continuous operation, expose your Eco-Drive watch to light regularly. Avoid storing it in dark places for extended periods, as this can deplete the power reserve and cause the watch to stop. If the watch stops, expose it to bright light to recharge.

4. Environmental Considerations

Avoid exposing your watch to extreme temperatures (below 0°C/32°F or above 60°C/140°F) or strong magnetic fields, as these can affect its accuracy and functionality.
