I saw it too in the flesh, and I don't really know what to think....
I, for one, wish that the - so far very quite - JLC collecting world will not be affected by a frenzy of 'amazing defective dials' similar to what we know with another brand.
Although this aged brown dial is 'interesting', there is no way I think one should accept to pay more for this type of defective dials (and we also know that there are some artists who master the ways to 'age' dials and bezels).
Be it for a submariner, a speedmaster, and now a Polaris, I think these dials should just be considered inferiors as perfectly preserved ones.
