The capacity or recharging efficiency of a rechargeable battery may gradually deteriorate for various reasons, such as long-term use or usage conditions. Worn or contaminated mechanical parts or degraded oils may also shorten recharging cycles.
We recommend you have it serviced (overhauled) every 3 or 4 years in order to ensure it functions perfectly and will be able to be used for a long time.
An overhaul is like a health checkup for a watch. It is important to check inside the watch for retention of oil lubrication, looseness of screws, rust from dirt and sweat, and deterioration inside the case. By having an overhaul, dirt and sweat on an unseen part will be cleaned off, preventing a
malfunction. In addition, any worn out parts and gaskets will be replaced to ensure that functions and water resistance works perfectly like a new watch.
If you need an overhaul, please contact the nearest Customer Service Center.
