Setting the Time and Date
Eco-Drive time and date setting involves crown positions and hand movements; the perpetual calendar requires setting the second hand to the correct month and year.
Standard Time Setting Procedure
To set the time on your Citizen Eco-Drive, gently pull the crown out to the first click (position one). This allows for independent adjustment of the hour and minute hands. Rotate the crown to move the hands forward until they display the correct time. Ensure the date changes at midnight, indicating AM/PM is correctly set.
Carefully push the crown back in to its original position (zero position) to secure the time setting. Avoid adjusting the time during periods of low light, as this may affect the watch’s charging cycle. Always double-check the time after setting to confirm accuracy.
Setting the Date (Perpetual Calendar)
For Perpetual Calendar models, pull the crown to the second position. Rotate it to move the second hand, using it to indicate the month (e.g., 4 for April). Then, calculate years since the last leap year and adjust the second hand accordingly – three years equates to 23 minutes past the hour.
Confirm accuracy, as incorrect settings can lead to date errors like displaying the 31st of months with fewer days. This process requires precision; a faulty setting may necessitate a full reset and resynchronization.
Adjusting for Leap Years
Leap year adjustment is crucial for the Perpetual Calendar’s accuracy. Determine the number of years since the last leap year. For instance, three years after a leap year, the second hand should be advanced three minutes past the hour during date setting.
This compensates for the extra day, ensuring the calendar correctly progresses through February. Incorrect leap year settings directly contribute to date display errors, like showing the 31st when the month only has 30 days, highlighting the need for precise adjustment.
Using the Chronograph Function
Chronograph functionality, available on some Eco-Drive models, requires switching to chronograph mode and utilizing the pushers for starting, stopping, and resetting measurements.
Starting, Stopping, and Resetting the Chronograph
To initiate the chronograph, typically, you’ll need to be in chronograph mode. Pressing the top pusher usually starts the timing. Another press of the same pusher will halt the timer, allowing you to read the elapsed time.
Resetting the chronograph to zero often involves pressing the bottom pusher.
