It's defintely not blue at all. I have this one on order, I tought it was a kind of blueish grey, or greyish blue, but, it's sunburn grey
I assume that "blue" one is just a natural blue sky lightning reflect on the watch.
Evora
It will be released soon, the watch (rep) is quite ready ;-)
Quite disappointed to have mine (gen) on order since a few months :-(
