It is hard to say if it was relumed, the fact that the hands match the lume plots is a good sign, even if I've read that the lume on the hands should be darker. The CB case/perlage are correct for both a 65 and 66, but the seller says its from 1966 based on the movement number. It could be a 105.012-65 produced in 1966.
I was tempted by the watch but I'm not in the market for one, it looks very good (apart from maybe the bezel)
