If your watch has Lumibrite
Lumibrite is a luminous paint that is completely harmless to human beings and natural environment, containing no noxious
materials such as radioactive substance.
Lumibrite is a newly-developed luminous paint that absorbs the light energy of the sunlight and lighting apparatus in a short
time and stores it to emit light in the dark.
For example, if exposed to a light of more than 500 lux for approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours.
Please note, however, that, as Lumibrite emits the light it stores, the luminance level of the light decreases gradually over time.
The duration of the emitted light may also di󱐯er slightly depending on such factors as the brightness of the place where the
watch is exposed to light and the distance from the light source to the watch.

The battery used in this watch is a special secondary battery, which is totally di󱐯erent from ordinary silver oxide batteries.
Unlike other disposable batteries such as dry-cell batteries or button cells, this secondary battery can be used over and
over again by repeating the cycles of discharging and recharging.
However, for various reasons such as long-term use or usage conditions, the capacity or recharging e󱐰ciency of the
secondary battery may gradually deteriorate. Worn or contaminated mechanical parts or degraded oils may also shorten
recharging cycles. If the e󱐰ciency of the secondary battery decreases, have the watch repaired.
When the secondary batter y is fully charged, the overcharge
prevention function is automatically activated to avoid further
charging. There is no need to worr y about damage caused by
overcharging no matter how much the secondary battery is charged
in excess of the "time required for fully charging the watch".

■ Remarks on replacing the secondary battery
・ Do not remove the secondary battery yourself.
Replacement of the secondary battery requires professional
knowledge and skill. Please ask a watch retailer for repair.
・ Never install a silver oxide battery for conventional watches in place
of the KINETIC E.S.U., which can generate heat that can cause
bursting or ignition.
