The finishing on the Eichi is remarkable and has no peer within the house of Credor, but solely from a design perspective, I do prefer the simple second hand on my Kuon over the Eichi's crescent accent (which I've always found a bit odd), for instance.
The crescent just gives you another reason to look at the dial, here you can see it "cradle" the power reserve hand I really like the Kuon. I wanted to see one in live photos to see how that bracelet works. It sounds like you are happy with it? Cazalea ...
