<Periodic Inspection (Charge Basis)>
• Water resistance
As the water resistance will be reduced over time, you should have your watch inspected and its water
resistance verified every 2-3 years (charge basis) to extend its life and ensure safety. To maintain its water
resistance, it is recommended to request us to replace the packings and other parts of your watch.
• Disassembling for internal cleaning (repair)
You should have your watch disassembled and its internal components cleaned periodically to extend its life.
Lubrication oils are used to reduce wearing of moving parts such as gears. However, over time the lubrication
oils will degrade and wear will increase, eventually resulting in malfunction. Please have your watch undergo
internal cleaning once every 5 years as a guide.
<Other Inquiries>
If you have any questions regarding the warranty, repairs or other matters, please inquire at the shop
where you purchased your watch or Customer Support Center.
