Hey Dino, from a while back, I did not realize that the previous iteration of Daytona (the Zenith Daytona) did not have a brushed bracelet. I was confusing the PCLs with the polished lugs.
With that said, I love all forms of the Daytona. One of the greatest sport chronographs. When I put the black dialed version on my wrist, I certainly felt the draw. I can't help but feel it is a bit duplicative in my small collection though, with my Speedmaster and all. Not to say that they are even remotely similar. But at least in my small collection, two black dialed sports chronos may be a bit too much. Nonetheless, I would love to add a Daytona to the stable one day.
Yes, the only new polished surface with the introduction of the present 116520 were the lugs.
Obviously, we all have to decide in what direction we want to go with our collections. What may be missing or a gap in one person's collection may be redundant or unnecessary in another. IMHO, while they are both black dial chronographs, both are different enough (bezel, movement auto v. manual, subdial layout and colors, bracelet, water resistance, screw pushers v. plungers) that I wouldn't see them as duplicative, but that doesn't mean its the right watch for you. There are plenty of great watches and only so much $$$ and wrist time.
