Hallo Henrik,
Guten tag!
And as for your question, I get what you mean.
Although it may seem that the lume of the lower dial might shine through there, the ecru-coloured portion that could be seen from the hole is NOT superluminova, therefore no light will shine through there in lume mode. You can confirm from the last lume shot of the piece, this was taken at an angle itself slightly from the bottom left hand corner, if it indeed shone through as you have thought, you would see the lume here. It is so bright that even a blurred shot would capture it, that's how strong the lume was especially when freshly charged with a real strong torch!
Danke and glad to hear you enjoyed my report!
Was it the way Chronos would have written it?
