Yeah, but I figured I would offer some DIY advice, instead of just shilling a product outright.
Tritec products don't look or react like Tritium. I think I am speaking for people in favour of the people who want to modify their 187 more to look like the real thing ... it already comes with non-radioactive looking lume on it, you don't have to pay extra for that look.
The fact that GLOW INC. costs ~$8 an oz. vs ~$40 a gram is not lost on those of us who do modifications for ourselves (and even those that do it as a service. Provide Ziggy the lume and I bet his labour prices are much better!) Tritec comes in a variety of colours, but that doesn't change it's glowing properties and one thing Tritec isn't, is subtle. A GEN PAM187 is a beautiful watch, the Tritium on it glows with a deep, fuzzy glow, like comparing a candle to an electric lamp. It looks warm, radioactive, as unhealthy as a Cuban Cigar instead of veggie nibbles at lunch.
Sometimes it's not a contest of who's brightest wins. Good mods aren't garish or overpowering, they are like the originals, blends of design and concept. Gen Panerai aren't adverts for Lume paint companies. The dial glow is integral, with the rest of the design.
