Looking at the images here..Lange seems more frumpy and formal..Cellini more fun..
One for the more "mature" crowd..
The other for a more fun loving and perhaps.. younger set of mind..
Though the blue goldstone version of this Lange..
Seems to defy what I just said..and would be the one I would buy..
