The Longevity of Citizen Eco-Drive Watches: A Comprehensive Guide
Citizen Eco-Drive watches are renowned for their remarkable longevity and reliability. Known for utilizing solar power technology, these watches last for extended periods without the need for traditional battery replacements. This article delves into the factors that influence the lifespan of Citizen Eco-Drive watches, their maintenance, and advice from a long-term owner.
Introduction to Citizen Eco-Drive Watches
Citizen Eco-Drive watches were developed to harness the power of the sun through a unique battery system that can last up to 10 years or even longer. These watches feature a titanium lithium-ion battery, which, despite its impressive lifespan, does have a finite duration. The watch's performance relies on the consistent availability of light to charge the battery.
Factors Affecting the Lifespan of Eco-Drive Watches
The primary factor influencing the longevity of Citizen Eco-Drive watches is the quality and maintenance of their components. Regular exposure to natural light, a combination of mechanical and solar power, and proper care contribute to the extended lifespan of these timepieces.
Light Exposure: The watch's ability to function depends heavily on adequate light exposure. The solar cells convert light into electrical energy, which charges the internal battery. Even after 10 years, the watch may still operate efficiently if continuously exposed to light sources.
Regular Maintenance: Regular maintenance, such as servicing and replacing worn-out parts, can greatly enhance the longevity of the watch. Citizen recommends that water-resistant and diving watches should have their gaskets exchanged every 2 or 3 years to maintain water resistance. Additionally, periodic servicing of the watch movement is necessary to ensure smooth operation and extend its life.
Long-Term Ownership Experience
Based on personal experience, Citizen Eco-Drive watches can last for decades. My own Citizen Eco-Drive Calibre 2100, purchased from Jomashop for 265 MSRP, initially came with a 5-year warranty. Around 2018-2019, I noticed a decrease in the watch's power reserve, dying after 4-6 hours after being fully charged. After investigating, it was determined that the power cell needed replacement. Attempting to do this myself was not feasible due to welding techniques used in some models. For this reason, professional repair was the only option, which proved to be quite expensive.
Battery Life and Replacement
The battery in Citizen Eco-Drive watches is designed to last up to 40 years, though this is rare. Lithium-ion batteries, like the ones used in these watches, typically have a set number of charge cycles before they degrade. Citizen claims that their solar cells and secondary batteries will last more than 10 years, with retaining 80% of their initial capacity after 20 years. The batteries are available for purchase online for around 25 MSRP. When the battery does need replacement, it can be done by a professional, ensuring the watch maintains its accuracy and functionality.
Conclusion
In summary, Citizen Eco-Drive watches can last for many years, provided they are regularly maintained and exposed to sufficient light. The combination of solar power and battery technology ensures that these watches can continue to function efficiently, even after extensive use. For those seeking a reliable and long-lasting timepiece, Citizen Eco-Drive watches are a commendable choice.
