Firstly, congratulations on getting this watch. A steel, manual wind amagnetic vintage from Patek Philippe. It is as rare as it is exquisite. Congratulations to you.
Series 1 and Series 2 3417s are close-to the epitome of Calatrava collecting. In fact, i would go as far as to say that with this one in the bag, hunting other Calatravas will have an edge taken away. You have probably one of the coolest watches made by Patek Philippe. Massive congratulations to you!
