Re-lumed question

[mattg6]

Have the hands on the left 1680 been re-lumed? On the right is my 16800 and everything looks lumed under UV. On the left is 1680 from 1977. Insert is replaced clearly given the pearl color. And then the hands - are they relumed? They look “dead” but I was also told that they don’t have to glow to be tritium/original, it just depends on the tritium vs zinksulfide mixture. Maybe they’re not relumed but not original? Any input or insights appreciated
