Wow i like to see the 42mm chrono in real. Tried once on 45mm chrono and found it to be too thick and chunky for a dressy watch, even bigger than my 44 big bang.
... this 42mm is relatively new, but very low profile at the boutique or ADs. I like the date back ground color and the size is just. It may look grey, and 45mm version is called "King Grey", but 42mm version was black to my eyes, and the case is "King Gold", so check the ref number I posted and it may be exactly what you are looking for...
