I'm new to both this forum and the world of mechanical watches in general so apologies if this is an obvious question... but I came across this picture and fell in love with this watch.
Since I have become fascinated with the history of IWC and their pieces but haven't come across any instances of what I am presuming is a Portofino Chronograph with a black case. Any help would be greatly appreciated. Maybe it's my imagination and it's a simple stainless steel case reflecting a black background???
