If your watch is a diver's watch
[4] When Luminous Paint is used for your watch
The paint on the dial and hands helps you with reading the time in a dark place. The
luminous paint stores light (daylight or artificial light) and glows in a dark place.
It is free from any radioactive substance or any other material harmful to a
human body or environment.
• The light emission gradually becomes weaker as time passes.
• The duration of the light (“glow”) will vary depending on the brightness, types
of and distance from a light source, exposure time, and the amount of the
paint.
• The paint may not glow and/or may dissipate quickly if exposure to light was
not sufficient.
