Without a doubt, the best looking perpetual calendar of Patek's modern era, this 18ct white gold ref. 5320 has a beautifully sculpted case with dramatically stepped 'three tier' lugs and crisp bezel. The distinctive cream dial, syringe hands and luminous arabic markers are inspired by a unique stainless steel perpetual calendar from 1944. Complete with its original Patek Philippe winding box, certificate of Origin, booklets, stylus and additional solid 18ct gold caseback. Fitted to a brand new brown Patek alligator strap and secured by the 18ct white gold Calatrava clasp.
