imho it's all down to personal preference or taste. I used to have a 6105 with relumed dial and hands
and still have this 6105 with relumed hands only
Speaking of (my) taste. I don't like a relumed 6105 dial and would only relume the hands if necessary, e.g. to protect the dial in case the hands already show black discoloration due to moisture. So, I would relume only the hands if necessary and keep the rest as is.
