to my collection. I narrowed it down to 3 choices. 5970 J - classic, warm, beautiful in an almost vintage way and the least common of the 5970s. 5970P - also somewhat limited in numbers (say 500 ish), bold but beautiful and perhaps most important, platinum. For me platinum, the so called most noble of metal is well ... platinum! 5270P - I love salmon dials on white metal watches. I like that the day/night and leap year indicators are separate from the registers at 3 and 9. And of course it is platinum. But when it came down to a choice I believe that the 5970 is about as perfect as a watch can be. It has become a classic and won’t be too long before it is considered vintage. Bottom line, I realized that I just loved the 5970P the most of the 3 choices. Best, Patekova
