It wasn't easy to find. I wanted to have it in the original orange color with silver details, and in the narrow version.
Everything looked fine in London...except the size. The nice sales assistant said it was too big for me as my wrists are pretty small, but unfortunately they didn't have it smaller at that moment...Finally found it in Hermes boutique at Munich Airport!

There're two options with the sizes: PM is smaller (diameter: 6cm) and GM bigger (diameter: 6,5cm).
