For Repairing The Watch; Note On The Luminous Dial - Citizen Eco-Drive b740 Instruction Manual

CAUTION
• This watch must be repaired by an authorized Citizen Service Center only.
CAUTION
• The luminous paint used for the dial of this watch is mainly made from light
accumulating materials, which are harmless to the human body and the
environment since it contains no toxic substance such as a radioactive
material.
This luminous paint accumulates light of the sun and indoor lighting and
emits light in a dark place. However, its luminance gradually fades because
it discharges accumulated light. The duration that the luminous paint emits
light differs depending on the illuminance and distance from the light source
when it accumulates light.
If the luminous paint accumulates insufficient light, it will not emit light in a
dark place, or even if it emits light, its luminance rapidly fades. Therefore,
carefully expose the luminous dial to light so that the luminous paint
accumulates sufficient light especially before diving. It is recommended that
you use an underwater flashlight to apply light to the watch during diving.
