Now, that is a post I love.
I'm as happy as you are with your choice Scone, believe it or not.
I sincerely think you made the best choice.
I would have gone with this one if I already had a matte dial.
That is why I went for the 16800.
I think Alligoat is right (again). There were no matte dials for the 168000.
If I remember well, the chronology is 16800 matte, 16800 WG markers, 168000 WG markers, 16610.
Wear it well and enjoy!
Cheers
Stephane
