Wore Cristalle for years, currently own a bottle of the Chanel Eau de Cologne from the Exclusifs range.
The Eau de Cologne is a much drier, much simpler scent than Cristalle. Cristalle has an overall dewiness, way more green notes, and a lot more happens as the top notes dry off. I do love the Eau de Cologne, though, and consider it an exemplar of its type. The lemon in it seems to combine both the peel and the juice and is absolutely laser-like in its briskness. Wish it came in a splash bottle so I could do it justice.
