How to Change the Day and Date on a Citizen Eco-Drive Watch

Citizen Eco-Drive watches are renowned for their solar-powered technology, reliability, and sleek design. However, like any analog watch with date and day functionalities, setting the correct day and date is essential to ensure the watch operates smoothly and accurately. Whether you just bought a new Eco-Drive or need to adjust it due to a change in the time zone or calendar, here’s a detailed guide on how to change the day and date on your Citizen Eco-Drive watch.

Understanding the Basics

Before adjusting the day and date on your Citizen Eco-Drive watch, it’s important to understand the basic components of the watch's dial and crown. Typically, Eco-Drive watches have a three-position crown system:

• Position 1: Pushed all the way in – this is the normal operating mode, where the watch keeps time.
• Position 2: The middle position, which is used to adjust the day and date.
• Position 3: Pulled all the way out – this position is for adjusting the time.

The crown is usually located on the right side of the watch and serves as the main control for setting the time, day, and date. Depending on the model, your watch may have a screw-down crown for additional water resistance, in which case you’ll need to unscrew it first by rotating it counterclockwise before pulling it out to the appropriate position.

Step-by-Step Guide for Changing the Day and Date

Step 1: Unscrew the Crown (If Applicable)

If your Citizen Eco-Drive has a screw-down crown, start by unscrewing it. Rotate the crown counterclockwise until it pops out slightly, allowing you to pull it into position. Be gentle, as forcing the crown can damage the threading or mechanism.

Step 2: Pull the Crown to the Correct Position

Once the crown is unscrewed (if necessary), pull it to the second position. This is the position used for setting the day and date. You’ll notice that in this position, rotating the crown in one direction will adjust the date, while rotating it in the opposite direction will change the day.

• To Change the Date: Rotate the crown clockwise.
• To Change the Day: Rotate the crown counterclockwise.

Note that the day of the week may be displayed in different languages depending on the model. Make sure you choose the correct language setting when adjusting the day.

Step 3: Adjust the Day and Date

Carefully rotate the crown to set the correct day and date. Ensure that you are setting the day and date for the correct AM/PM period. Many analog watches, including Eco-Drive models, cycle through the day and date at midnight. If you set the watch in the wrong period (AM vs. PM), the date may change at noon instead of midnight.

For example:

• If today is August 26 and it’s currently 9 PM, make sure the date and day are set to reflect the PM period.
• Rotate the crown slowly to avoid skipping the desired day or date.

Step 4: Return the Crown to the Normal Position

After adjusting the day and date to the correct settings, gently push the crown back to the normal position (Position 1). If your watch has a screw-down crown, remember to screw it back in by rotating it clockwise to ensure water resistance.

Common Issues and Troubleshooting

1. The Date Changes at Noon Instead of Midnight:
This issue occurs when the watch has been set in the wrong AM/PM period. To fix this, pull the crown out to Position 3 and adjust the time forward by 12 hours to ensure the watch is set to the correct period. Then, reset the day and date as needed.

2. Difficulty in Setting the Day/Date:
If you are having trouble adjusting the day or date, the problem could be related to the position of the crown. Ensure that the crown is in Position 2 when setting the day and date. If the crown is in Position 1, the watch will not allow these adjustments.

3. Day and Date Do Not Change Automatically:
If the day and date do not change automatically at midnight, this could indicate a mechanical issue. Citizen Eco-Drive watches are built with high precision, but like any mechanical device, they may require maintenance or repair over time. In such cases, it is best to take the watch to an authorized service center for inspection.

Tips for Setting the Day and Date Correctly

• Avoid Setting the Date Between 9 PM and 3 AM:
  During this time frame, the internal gears of the watch are engaged in changing the day and date automatically. Attempting to manually adjust the day and date during this period can damage the movement. Wait until after 3 AM or before 9 PM to make any adjustments.

• Use the Quick-Set Function (If Available):
  Some Citizen Eco-Drive watches come with a quick-set function, allowing you to change the date rapidly without affecting the time. Refer to your specific model’s instruction manual to see if this feature is available and how to use it.

• Be Mindful of Non-Standard Calendars:
  Certain Eco-Drive models may feature additional complications, such as perpetual calendars or moon phases. Setting the date on these models can be more complex and may require specific instructions unique to the model.

The Perpetual Calendar Feature

Some higher-end Citizen Eco-Drive models feature a perpetual calendar, which automatically adjusts for months with different numbers of days and even leap years. If you own a perpetual calendar model, setting the day and date correctly the first time means you won't have to adjust them again unless the watch stops running.

To set the perpetual calendar, follow the same steps as outlined above, but consult your watch’s instruction manual for additional guidelines specific to perpetual calendar models. These watches have more intricate movements, and it is crucial to follow the steps precisely to avoid misalignment in the calendar function.

Maintaining Your Citizen Eco-Drive Watch

Regular maintenance is key to ensuring your Citizen Eco-Drive watch operates smoothly. Here are a few tips to help you keep your watch in top condition:

• Exposure to Sunlight: As an Eco-Drive, the watch is powered by light, so regular exposure to sunlight or artificial light is necessary to keep the battery charged. If the watch stops running, it may simply need to be recharged by placing it under light for several hours.
• Water Resistance: Ensure that the crown is always pushed in (or screwed down) when not adjusting the time or date. This will help maintain the watch’s water resistance.
• Service Intervals: Even though Eco-Drive watches are low-maintenance, it's a good idea to have them serviced every few years, especially if they experience heavy wear.

Conclusion

Changing the day and date on your Citizen Eco-Drive watch is a simple yet essential process to keep the watch functioning accurately. By following the steps outlined above, you can ensure that your watch is set correctly and remains a reliable timepiece. Proper maintenance and understanding of the watch's features will allow you to enjoy your Eco-Drive for many years to come.

Citizen has built its reputation on creating high-quality, eco-friendly watches, and with a little care and knowledge, you can get the most out of your timepiece.
