Adjusting the calendar function on a Citizen Eco-Drive watch is a crucial aspect of ownership. This process involves setting the correct day of the month, and sometimes the day of the week, ensuring accurate timekeeping. For example, after the end of a 30-day month, the date must be advanced manually to the 1st of the following month. Different models may have varying methods, often involving the use of the crown or push buttons.
Proper calendar setting prevents inaccuracies and maintains the watch’s reliability. Historically, calendar complications have been important features in horology, offering wearers increased practicality. With Eco-Drive technology, this functionality combines traditional watchmaking with modern light-powered convenience. Accurate date display remains a valuable asset for both personal and professional use.
