The Hublot Big Bang Integral Ceramic is not a new model but it was only available in black, white. blue and grey. This year Hublot launched some new colors -- perhaps just in time for the summer -- Blue Indigo, Sky Blue, Beige and Green
The sky blue is certainly a summer color. The integral ceramic is very comfortable on the wrist and very light. It seems a fashion/trendy color but not sure on how it would feel after owning it long term.
Indigo blue is perhaps more business -- but probably not as it is a very vivid indigo blue. Of course we are looking at colored versions so the "business" one would probably be the more traditional black or the grey.
