Hi There,
Congrads on the new watch.
it really comes down to what suit you best....
Rolex Submariner is a good daily wear piece so should be a good item to add on to a collection...
Franck Muller Conquistador on the other hand, i will say is like a Durian Lover, is an Exquisite Taste...but if you are a modern/contemporary watch lover, then i think it should do just fine...
Hublot BB is quite an unique piece, depends on what material you are getting, but i personally think the rose gold version is a classy one. In general, I always see Hublot as a fashion watch than a Swiss collector watch. (maybe because is owned by LV)
