hi lara,
and what would you like to know from us?
all i can say right now: normally a PhD is 3-4 years, or longer (in the US, or when working part-time).
as you mentioned switzerland: i have heard of a few exceptional cases in switzerland (i am swiss myself) where students who wrote a very comprehensive master's thesis (like, for example, 200 pages, including substantive research) went on to do a very fast PhD in which they basically just expanded on their master's thesis. it took them only 1.5 to 2 years. so i am not saying it is totally impossible to finish your PhD fast. but one year is quite unlikely.
