A few more thoughts
If you are strongly drawn to the watch, I do not think that you will be at all disappointed with it -- in my opinion it very much stands up to (or even exceeds) the expectations that I had for it.
I've seen the Dune, and I think that it looks great. On some of my other watches (in particular my two Voutilainen pieces) I have RG cases with rhodium/silver movements, and the contrast really makes the movement "pop." The same is true for the Dune, in my opinion.
Looking at the watch on my wrist, I would guess it at 42mm, even though the actual size is 43mm. The case band actually protrudes past the edge of the bezel by almost a mm on each side, so the bezel is probably between 41 and 42 mm across from edge to edge. Also, the bezel is fairly thin but certainly not as thin as those on the Voutilainen watches, which tend to wear "big" relative to their actual sizes. The lugs on the One Hertz also curve down nicely (and fairly rapidly) from the case, so you don't need a huge wrist for the watch to look good. I wear a Lange Double Split a decent amount of the time, and it seems bigger to me than the One Hertz. Of course, the One Hertz is (and looks) bigger than pieces such as the Dufour Simplicity -- but to me the dimensions of the watch are entirely consistent with its overall appearance.
Hope that helps -- I certainly don't have any interest in "pushing" you toward a purchase, but would be delighted to welcome you to the Grönefeld owners' "club" if you do make the choice! Please keep us informed here on the forum as you go through your decision process.
Best,
