Reinterpreted in platinum. The Ref. 5270 Chronograph with a perpetual calendar continues a grand Patek Philippe tradition that began in 1941. It was launched in white gold in 2011, followed by a rose-gold version in 2015. Now, the manufacture pays special tribute to the technical finesse of this grand complication, introducing it in precious platinum for the first time.
