Calatrava with cal. 215 PS - the movement is bulid for decades, only 18 jewels but 28800 A/h or Calatrava Grand Tailler, ca 315 SC with only 21 600 A/h (30 jewels) does not sound up to date.I know that thy developed a Silinvar spring movement recntly but its not the price range i am looking for...so that movement is up to date but out of question.
I am quite new to Patek and am looking forward to your answers and input
