The Grand Carrera is an Amazing and Gorgeous Timepiece. Though the 6000 series is out of production they are still very sought after by collectors and consumers willing to spend a big buck even on used examples. By changing the size you could key in on people from the "New Watch Generation" and bring back the original fans who liked theirs so much. The dial design could be dressed up with different markers, numbers and color schemes. The 6000 series chronometer and chronograph could also both be brought back . The world may even be ready for a PVD 6000 series, imagine that.
