Hola,
Pues según este link, de fabricantes que tienen la licencia para Europa (LumiNova AG Switzerland), esta se puede cargar y recagargar durante "toda la vida del reloj" sin efecto de envejecimiento:
"These pigments operate like a light battery. After sufficient activation by sunlight or artificial light, they glow in the dark for many hours. Larger markings guarantee full legibility 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. Consequently, Super-Luminova® offers full high-performance over lifetime of a watch."
Super-LumiNova® pigments are environmental friendly, non-toxic, and absolutely free of radioactivity.
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 Swiss Super-LumiNova® pigments.
El Titrio dejar de estar activo sobre los 15 años.

En el apartado de la Super-luminova hay alguna foto de diales de Omega
, incluyendo el speedy.

Curiosa la cantidad de aplicaciones diferentes....
Un saludo,

P.D.: Vaya, resulta que Rolex no hace su propia super-luminova
