Life Span of Luminous Materials Used On Hands and Dial?

I assume Limes does not use a radio luminous material on their watches (tritium), but rather a photo luminous material. Does Limes use a proprietary material, or "off the shelf" stuff that is commonly used elsewhere? I'm not trying to get Limes to give away any trade secrets. Regardless of what is used, what I want to know is what is the expected life span in years that a Limes watch will remain sensitive to luminous activation . Does it have a life span like a radio luminous coated watch (e.g., tritium, 25 years max.)? It would be nice to know that if my Limes watch is handed down over the years, it will still glow in 50 years. Thanks.
