The non steel versions come with 3 straps: leather, rubber and steel
The gold ones come with only two: rubber and leather. If you want the gold bracelet as well it’s extra (understandably)
My wife has that same color rubber strap as your friends wife has.
Personally I think it’s nice but no more.
On the other hand, she’s also got the high gloss dark green leather strap and a dark blue leather strap, both are stunning (in my humble view).
