I saw the scent today at Karstadt (Berlin) and immediately tested it; it smells very intense of mandarin and still contains the Cool Water DNA.
The longevity is likely between 4 and 5 hours, and the price for 100ml is around €50 (RRP). This version is limited, and if you're interested, you should act quickly as you never know how high this edition is and especially whether any will be produced again.
The scent manages to create a bridge between film and fragrance lovers, because, and this is very important, IT IS NOT MERCHANDISE! Rather, it is a collaboration between Davidoff, the designer brand, and the film people who developed the movie; you could also wear it perfectly for a movie night.
The scent itself smells very delicious of mandarin and makes you long for the sea; it is not intrusive, not exciting, and also not overpowering. You could actually wear it in any season, but I can well imagine that many will prefer it in summer due to its freshness.
The bottle makes a nice impression; it transitions from white to a beautiful dark blue gradient, with the Davidoff Cool Water logo in the middle and the Aquaman logo underneath.
