Rolex Daytona 116520 Chromalight
Rolex Daytona 116520 Chromalight is a particular Daytona recognizable by the luminescence of the indexes. When the first Daytona 116520 watches have been delivered in 2000 to the official dealers, the material used for the luminescence of the indexes was Superluminova. After 2009, Rolex introduced a new material called Chromalight.
For this reason, the last batch of production of Daytona 116520 could have Chromalight instead Superluminova.
A Daytona 116520 Chromalight could be even APH.
Batch of production
It appears since 2009 (serial V) to the end of production (random serial number) and its presence grows over time: rare for the first ones, very common for the last ones. Chromalight used in platinum and gold Daytona as well.
