Q
Is any radioactive substance used for luminous paint on watches made by CITIZEN?
A
The luminous paint currently used for our watches produced and sold does not contain any radioactive substance. Light storing pigments are used instead.
However, promethium 147 (half period: about 2.6 years) was used for luminous paint of some products before 1998, complying with laws which set its safety standard at that time.
