Boucheron Eau Légerè blue bottle

Hi everyone,

I am trying to work out if there are more than one bottle design for Boucheron Eau Légerè 2005 edition.

My own bottle has a blue cap on the top and a blue part in the glass. It looks very much like one of the photos shared on the page (the one with the cat). But the other photos show a bottle with no colour and a golden or yellow cap.

Can anyone tell me why there are two designs?

Thanks a lot!
