Audemars Piguet

Has anyone seen the new Royal Oak Offshore Marcus Edition? I was walking past hte Marcus store on new Bond St, and saw a black cased Offshore with white markers and a white rubber strap. Looked pretty cool, i had seen the older red and black before but no... 

But there is a Hublot that matches your description?

It could be a "Marcus Special" as Marcus does have these so that he can charge the full price + as a special edition Cronolust
