Reference 5270, launched in 2011, is heir to several generations of Patek Philippe perpetual calendar chronographs. The Manufacture reinterprets this timepiece in a model featuring an iconic yet original style. The radiance of platinum E28094 the most precious metal of all yet also the hardest to work with E28094 magnifies the timeless design of the case, with its concave bezel, its elegant two-tier lugs and its correction push-pieces that are satin-brushed on the flanks and polished on top.
