This is a stunning Patek Philippe ref. 3520 from the 1960’s. This reference was originally released as the flattest waterproof watch in the world. This example is very special with its perfectly proportioned breguet numeral dial in very nice original condition. The case is 32mm but wears larger and has its original finish. Overall it’s one of the most beautiful Calatrava I’ve had and it’s even better in person!
