• For models with a 24-hour format, ensure you set the time correctly for AM or PM.

Step 4: Set the Date and Other Complications

• Pull the crown out to the first click to adjust the date. Turn the crown to set the correct date.
• If your model includes additional complications such as a day display or a perpetual calendar, refer to the user manual for specific instructions on setting these features.

Step 5: Synchronize with Atomic Time Signals

If your Citizen Eco-Drive E870 model features atomic timekeeping:

• Ensure the watch is in an area with a strong signal reception.

Step 6: Check and Confirm Settings

After completing the reset process:

• Confirm that the time, date, and other settings are accurate.
• Push the crown back to its original position to secure the settings.

4. Troubleshooting Common Issues

• Watch Not Responding: If the watch does not respond during the reset process, ensure it is fully charged. If the issue persists, consider consulting the user manual or contacting Citizen customer service.
