Rolex Daytona 116520 APH
Rolex Daytona 116520 APH is a particular Daytona recognizable by the dial. Collectors have noticed that "COSMOGRAPH" has been written with a little space between R and A, like "COSMOGR APH". This is why this particular batch is called APH.
A Daytona 116520 APH could be even Chromalight.
