I'd suggest using the search. All of the Big Bangs are (except for a select few) are Chronos.
There's hundreds of dial, strap, and bezel combinations out there as welll.
The most standard is the Big Bang Stainless Steel.
Other Popular models are the "Black Magic", "Tuiga", "Tuiga Rose Gold", "Big Bang King Power Chrono" and a whole BUNCH of others.
Do some research and narrow your options down.
Asking a question like. "which hublot should i buy" is too general. Most are fairly accurate to the original, so it's difficult for us to help you if you don't give us any criteria
Lastly: Give your posts some time. Less than 12 hours had gone by before you posted again, between 10:30p, and 9am.. not a lot of people are at their computer
