My favourite is not a watch but a collaboration between Tudor with Breitling on movements sharing.
But in this case, a Tudor Black Bay Chronograph....
If not under dilemma of "Over size diver hands simply don't fit chronograph", a nicely designed Tudor Chronograph in any other form will be easily my favourite. Good collaboration with wrong model selection. Not to mention there are too many variation for Black Bay already in these 2 years.
Rolex Sky-dweller is not my cup of tea but the material change only itself is already a milestone. I won't consider until I got the Daytona C.
If really I have to choose one impressive watch, maybe I will consider the Cellini Moon Phase, which is something totally new to Rolex.
