Rolex 9001
ConfirmedThe Sky-Dweller caliber, and the most complicated Rolex in current-era production. The month is shown by twelve apertures around the dial periphery rather than by a register, which is an identifying feature visible at a glance and one that counterfeits reproduce poorly because it requires twelve precisely registered windows.
