The EC 5970p salmon with Sand blasted breguet numerals and hands is unique and the 5970g Salmon as mine from the London Saatchi exhibition is under 5.
As you may expect I prefer my 5970g version with the perfectly balanced dial as the original with white Chrono hand 5970 but the EC 5970p Salmon dial is stunning.
It is fairly clear that this dark sand blast feature was the inspiration behind the 5270p Salmon. I personally am not a fan of the dark use of hands and numerals. But I know there are many who are.
There are a few feature differences on the dial also.
Here is a picture of both. Hope this clarifies.
