I canβt tell from the picture, but this version has a baby blue dial, correct? Is that the reason you parted with your 15400 (which is a cornerstone piece for many people)? Regardless, this new one looks great on you.
I am not really sure what AP stands for anymore, and personally, I relate to little outside of the watches. It is the phenomenal designs that have always interested me, and in this regard, I still love AP.
