Luminous Light

Some models use luminous light.

Luminous light is a safe luminous paint that uses no radioactive substances.

  • It stores light from sunlight and artificial lighting and re-emits it.
  • Luminous light on the hands and dial lets you tell the time in dark places.

TIP

As the paint re-emits stored light, it becomes dimmer over time.
Depending on the amount of light stored in the paint, the emitted light may be weak or short-lived.
