The 116520 is the SS designation for the post-zenith caliber and has been so for a while. Starting with the V series though, there have been some cosmetic changes to the buckle - minor. By the way, does anyone know what annual productions are on the 116520?
Given that Platinum and Gold prices are roughly the same nowadays, it seems the premium for Platinum watches is a bit of a scam....??? Factor in the different tooling machinery costs required for platinum casing blah blah but it still doesn't compute....
