Now we have black lume as below photo. it glows well during dark. In the past, Customer asked for black lume, Factory always says the black glowing is very weak. they don't suggest to make black lume. but you know after years, it changes, the new product comes by the demand. as long as customer needs, factory will find a way to make it. This is Chinese strength. We apply it for watch hands as trial. it is nice. customer likes it. Me too. in the future, we can put the black lume on Watch dial, watch bezel insert. it is more option for Geeks.
It is Black lume on the backside of watch hands. after lume dry, it looks dark grey color compared to black painted hands. pls see below photo.
