I don't care about luminous abilities, but sloppily applied lume markers on some watches bother me. Watches that have big and noticeable lume areas, like BCE, you can't compare the rep lume application to gen's.
Funny that people were always complaining about Skyland lume dots, and you can't even see the problem with a naked eye (without looking very closely). But when you see a gen BCE dial... the smoothness of those sticks... and then compare it to rep's chewing gum lume, the difference is HUGE.
Also, most rep lume areas are too green when uncharged (esp. Breitlings). 'Ling lume is ivory white, not green.
