(2) About the Battery (Secondary Cells)
1 This watch uses a special-purpose secondary cell for a power source that
differs from a regular battery.
The secondary cell is not a regular disposable type of battery but is instead
a rechargeable battery that can be used more than once.
The battery charge and charging efficiency of the secondary cell may drop
little by little depending on the duration of use and usage environment.
If it begins to seem that performance has deteriorated, contact the store
where the place of purchase or your nearest ORIENT authorized service
center.
2 Be aware that the battery charge will not be maintained even if the crown
is pulled out to stop the watch.
(3) Replacing the Battery
!
WARNING
1 Do not remove the secondary cell from the watch.
2 Battery replacement requires highly specialized knowledge and special-
purpose tools, technology, etc. For assistance with battery replacement,

3 Do not use in combination with regular silver-oxide batteries as doing
so may cause explosion, overheating, fire, etc. to occur. The watch is
designed so as not to allow electricity to conduct even if used with a silver-
oxide battery.

sports, whereas playing such light sports as golf, etc., will not
