Ice blue is how Rolex tells you it is platinum.
Rolex reserves the ice-blue dial for platinum. That is the whole convention: if you see that particular pale blue on an Oyster Perpetual case, the case is 950 platinum, and the brown Cerachrom bezel on the Daytona was chosen to sit against it. The 126506 is the current generation of that watch, on calibre 4131.
It is a heavy watch. Platinum is about twice the density of steel, and the Daytona case does not shrink to compensate, so the first thing anyone says on handling one is that it does not feel like the steel version at all. The 950 alloy is also softer than gold, which means it marks more readily and polishes differently — something worth knowing before you buy a worn one.
It replaced the 116506, which ran from 2013. Both are platinum with the ice-blue dial and brown bezel, and both come with and without diamond markers. Tell us whether you mind which generation and whether the diamond indices are wanted or specifically not.
