This is quite impressive indeed, especially in around less than 15 years.
As concerning the salesperson, I imagine no they are not, at least not a majority but who knows... there are some enthusiasts in their teams.
As for you 3rd thoughts, no I don't think it is. The majority of the models are very different from one another. If I had to pick for instance one of the limited RM011, I know 2 or 3 I would choose from and I wouldn't be bother to see new ones coming afterwards. It is a wider choice array, it allows to change if we want to and it is much more interesting than having only one version during many years, which is a little boring with time.
Pictures are really nice and their website is one of the best among watch brands IMHO.
I'm glad you liked this post Elio and thank you for your nice coments 
Have a nice end of year holidays!
