What Is The Citizen Eco-Drive Watch? 

When they were first released in 1996, these watches represented several technological breakthroughs over other solar-powered timepieces on the market at the time. As the name suggests, Eco-Drive watches are eco-friendly and sustainable. Since they can be powered by both natural and artificial light, they have a lower environmental impact because they don’t require frequent battery replacement or disposal.

In a lithium-ion rechargeable battery, the energy is stored. The battery may be charged permanently and work endlessly. Eco-Drive products, with appropriate maintenance, are timepieces that will last a long time. 

Unlike traditional battery-powered watches, Citizen Eco-Drive watches do not require frequent battery changes. This not only helps the environment by reducing the number of batteries used, but it also saves you money and time.

Citizen offers a wide variety of Eco-Drive watch styles, from traditional to contemporary, that are excellent for both formal and casual occasions. There is a timepiece to match every individual’s style and preferences. 

How To Set Citizen Eco-Drive Watch

1. Set the date and day on Citizen Eco-Drive Watch

To begin, it is important to refrain from setting the day or date on any calendar watch between the hours of 9:00 PM and 4:00 AM, as such adjustments during this period can potentially harm the watch movement.

Set the date: To change the date, turn the crown in the reverse direction (counterclockwise). Keep turning until you reach the correct date. Note that some watches have a quick-set date feature, which means you can change the date quickly by turning the crown rapidly.

Set the day (if this feature is available on your watch): You can change the day by turning the crown in a clockwise direction.

Move the crown back in: After setting the day and date, move the crown back into its initial position so that it is firmly pressed on the watch case.

Confirm the settings: To ensure you set the day and date correctly, advance the time to the next day and check if the day and date change properly at midnight. If everything is correct, your Citizen Eco-Drive watch is now set.

You must move the calendar one day earlier to the current so as to change AM and PM hours accurately. As a result, you could change it to Wednesday if it were Thursday. The date should be changed correspondingly; if it is the 17th, change it to the 16th.

Move the Crown (Source: Google)

Move the crown: To change the time, turn the crown in either the clockwise direction or the opposite direction (counterclockwise). Rotate the hands around until the time is displayed properly. Remember that the majority of Eco-Drive timepieces contain a hacking mechanism, which causes the second hand to stop working when the crown is moved to the time-setting mode. This makes it easier to accurately set the time..

Setting AM/PM (if applicable): If your watch has a 12-hour format, make sure to set the correct AM or PM time.

Move the crown back in: Once you have set the correct time, move the crown back into its initial position against the watch case.

Confirm the time: To ensure you have set the time correctly, observe the time on your watch and compare it with a reliable time source, such as your phone or a wall clock.

Keep in mind that some Citizen Eco-Drive watches might have additional features or settings. If you encounter any difficulties or if your watch has specific complications, it’s always a good idea to refer to the user manual provided with your watch or visit an authorized Citizen service center for assistance.

How Can I Charge My Citizen Eco-Drive Watch?

Charging a Citizen Eco-Drive watch is a simple process, as these watches are powered by light and do not require battery replacements. 

Eco-Drive watches are designed to be charged by any source of light, whether natural or artificial. Sunlight, indoor lighting, or even ambient light can recharge the watch. The light is converted into energy by the solar panel under the watch’s dial, which powers the timepiece.

For the fastest and most efficient charging, place your Eco-Drive watch in direct sunlight. Avoid extreme heat or placing the watch near a windowpane on a hot day, as excessive heat can damage the watch. If sunlight is not available, charging under regular indoor lighting, such as fluorescent or LED lights, is also sufficient. However, charging might take longer compared to direct sunlight.

The time it takes to fully charge your Eco-Drive watch can vary depending on the model and the intensity of the light source. Most of the time, a few hours of exposure to light will be enough to fully charge the watch. In general, to achieve a complete charge, expose the watch to direct sunlight for 7-12 hours or place it under artificial light for 120 hours.

Power reserve indicator (Source: Google)

Some Citizen Eco-Drive watches have a power reserve indicator, which shows the amount of charge remaining. Refer to your watch’s user manual to understand how to interpret and use the power reserve indicator, if your watch has one.

Wearing your Eco-Drive watch regularly, especially in well-lit environments, will ensure it remains charged and fully operational. If you won’t be using the watch for a long time, keep it somewhere with light exposure to maintain its charge.

Importance Of Properly Setting The Watch

Properly setting the watch is of significant importance for several reasons:

  • Accurate Timekeeping: Setting the watch correctly ensures that it displays the correct time. 
  • Punctuality: A correctly set watch helps you maintain punctuality. You can efficiently manage your time by wearing a watch that displays the proper time.
  • Watch Functionality: Many watches have additional features such as date, day, chronograph, or world time. The performance of the watch can be enhanced by precisely adjusting these features.
