I was lucky to play with it for a few hours and it felt slightly larger than my CS, I was wearing that day. However, as you say - not a problem at all. Size is becoming more and more important for a watch to stay in my watchbox. This one is clearly within my tolerances.
I really love the way you describe the the sound. I totally get it. watching the Remontoir with its slow rotation is an other big point of this dial.
