In superb condition, this 18ct white gold Patek Philippe Annual Calendar with Flyback Chronograph, is totally complete with its original box and certificate from December 2017. The new chronograph pushers are finished with a beautiful guilloche pattern reminiscent of the important 'tasti tondi" Patek chronographs of the past. The textured blue dial and vintage brown calfskin strap with white stitching enhance the classic good looks, and it's worth remembering this annual calendar was also Patek's first automatic chronograph!
