Yeah Nanuq, I was thinking they were clearer than the others.
Only the inside the "cap" if you could call it that, was painted. The majority of the inner cavity is empty. It would be easy to change color.
His text in the auction reads like they are genuine......sorta
"new old stock original plastic luminous dot (according to market demand, it has been refilled with non-bright old luminous) for various vintage Rolex submariner models' bezel use, diameter is 2mm"
I have a brand new 5513 insert here with lumi pearl, and other than color they look alike.
I'm going to compare them under magnification tomorrow.
