It is not a mystery, I really like this one. I considered it many times. The play of transparency, light, and the big case goes very well with this version in my opinion.
It was issued in 2015, if my memory serves me well.
And also came a bit later, in steel blue,
And in gold.
The only one I was less mad about was the Earth to Sky Edition...
The blackened case and indices / luminous hands was just not my taste.
What do you think?
