I think it would be better with the power reserve indicator on the back.
I'm also of the opinion that it's a little on the large side as well. I personally like large watches but I find that the RL, while smaller than some of my other watches, wears quite large. So I would think that this would feel huge.
I'm pretty sure Lange will have no problem selling them all. I just wonder how many of them will see regular wrist time....
