My first PP was an annual calendar. I remember choosing between a 5035 and 5036. I bought the 5036 and flip it a few years when I saw the 5056 annual calendar.
I am still wearing my PP5056 today as I typed this. going 10+ years already!
Yes conservative is definitely the best word. For me it embodies perfectly Patek's identity (the annual calendar was invented by Patek in 1996). Thin but with a great character.
