It goes without saying that Seiko is a premier maker of affordable automatic, kinetic, and quartz movement watches. But, after the introduction of the now famous Orange Monster watch, Seiko became the leader in luminous material for hands, dials, and markers. The Orange Monster is the benchmark today for judging how strong and how long watch hands and markers glow in the dark.
Seiko's LumiBrite material is a dramatically improved fluorescent luminous paint that quickly absorbs more of the light-energy falling on it and glows brighter, for much longer, in the dark. Safe and harmless to human beings and the environment, it is completely free of radioactivity and can be used without restriction. A LumiBrite treated watch will glow at its full brightness after only brief exposure to bright light. Just a few minutes under normal room lighting will often be enough to charge the material, and much less under direct sunlight.
We feature both the Orange and Black Monster watches as well as many other Seiko dive and sport watches here that employ LumiBrite. We can assure you that under a full light charge there is nothing brighter or more impressive for reading time in limited light or darkness.
