'The notched rivet first made its rather sporadic appearance in the pre-spring collection of 2005. It shared its space with the round rivet for pre-spring & spring/summer of 2005 before finally replacing the round rivet completely in the pre-fall collection of 2005.'
In short, anything from pre-s (eg indigo, sky blue, dolma etc) could have either notched or unnotched rivets. The same is true of summer (AG, Turq, BG05) but I think the notches may have been more in evidence. Anything from Bordy 05, Calcaire, Ice Blue etc would have only had the notched rivets.
PS If you pinch your nose when saying the section inside the quotation it sounds much funnier.
