About Power Source for the Watch
The watch uses a dedicated lithium ion rechargeable battery.
Since a secondary battery (a battery that can be repeatedly charged and discharged) is charged using light received by
the dial, and do not need to be replaced periodically like a primary battery.
However, the capacity and charging efficiency of the secondary battery may decline depending on the long-term use
and operating environment. If the performance declines, contact your local dealer or TRUME customer support.
Also, if the battery is not charged for an extended period of time, it may discharge completely and you may not be able
to charge. If you cannot charge the watch even after exposing it to light, contact your local dealer or TRUME customer
support.
