First of all, thanks for the sumptuous photos, as well as for the great report!
YES, sumptuous - a superlative adjective that is underused these days.
My watch-day started with
1) a Milgauss in charcoal, a fine tool watch which I greatly appreciate when working with electro-magnetic fields, hidden magnets and such;
2) the Black Moon upon learning that Stepan had won something called the "Red Point" prize for "communication design" in Essen, Germany - only yesterday;
3) Vianney's Goldpfeil, while spending the afternoon with a friend, business partner, and a WIS on his birthday;
------
4) and right now THIS, the Korona RG, which outshines them all, even if the moon is now hidden from view.
All I can say is that you have acquired a treasure of a watch, that indeed has a stunning effect upon many who couldn't care less about watches - and certainly whambang upon me.
I try to make them care a little more, and explain a few things if I get them interested

P.S. The Helsinki grill-protecter looks a lot like my Korona K2, although I was more reminded of molten metal heated by a charcoal stove, beneath the grid.
