Since I disagree with you completely. I think the moonphase is the weaker part of the design, it's too "pretty", and a bit too big, for the very traditional aesthetic. The weirdly off-center RdM hews very closely to some of AL Breguets earlier pieces
(the oldest existant perpetuelle)
I can even picture the little dial flourishes in a contemporary piece, but I don't seem to have a picture handy. I find I like the guilloche one as well, but find it a bit too "same-old, same-old" The Breguet guilloche seems to be falling into a rut, it's all so flat when it isn't the Revaille du Tsar. I'd love an deep-cut RdM, to match the 18th C. assymetry
