When the rich went hunting in Africa they always wanted to shoot the big five: the buffalo, the lion, the elephant, the rhino and the leopard. These animals were the hardest to shoot. Swatch collectors have the same list: the Kiki, the Mimmo, the Puff, the original Jelly and the Andrew Logan. These 5 are the really hard to get. There will be rarer items, there may be more special prototypes, but these 5 will always be the big 5 of Swatch.
