Patek Philippe Calatrava ref.3563 Back-Winder Clou de Paris from 1975

This is an exceptionally rare and highly attractive Patek Philippe Calatrava reference 3563, featuring a back-wind automatic caliber 350T. Its striking Clou de Paris pyramid-textured gray-blue dial with tritium markers and hands sets it apart—an uncommon feature in Patek Philippe dress watches from this era. While this model is often found with integrated bracelets, this particular example stands out with its lugs, elevating the overall design and aesthetics to an entirely new level.
