Super-LumiNova
High Performance Phosphorescent Pigments
(Super-LumiNova)
These are a non-radioactive and non-toxic alternative for illuminating markings on time-piece (watch) dials and hands in the dark and are also called "photo-luminescent" or "afterglow" pigments. Selected grades of new chemical compositions have up to 100 times better brightness than previous zinc sulphide materials.
Nemoto & Co. Ltd. of Japan, patent holder of these new compositions and RC TRITEC Ltd. have formed the Joint-Venture LumiNova AG Switzerland, who are the licenced manufacturer and exclusive distributors and service center for Europe and selected overseas customers for Super-LumiNova® pigments.
All mayor watch brands use exclusively Super-LumiNova®
Super-LumiNova® pigments operate like a light battery. After sufficient activation by sunlight or artificial light, they glow in the dark for many hours. Larger markings are visible for the whole night. This activation and subsequent light emission process can be repeated again and again, and the material does not suffer any ageing.
Super-LumiNova® pigments are absolutely free of radioactivity.
Super-LumiNova® is available in ISO 3157 or ISO/DIS 17514 standard colours and many other shades. Before use they must be mixed with suitable RC TRITEC binders.
The luminous color, Super-LumiNova®, which is used for the time indication on Christopher Ward Swiss Movement Diving Watches, is a Swiss hi-tech product and is free of any radioactive substances. The principal of its function is to compare with light storage or a light battery. With sufficient activation of the pigments by artificial light or sunlight, they can emit in the darkness, during a certain time, their stored energy. The light is not emitted constantly, with progressing time less and less electrons fall back and the light emission will decrease steadily. This charging and discharging process is not depending on any wear and tear (unlike batteries).
