Yet, here we bring you another amazing timepiece released by Patek Philippe last month at Baselworld 2015. Here are our live pictures and hands-on review of the new Patek Philippe Split Seconds Chronograph in platinum ref. 5370P-001. Almost a century later, Patek wows everyone with the most amazing chronograph of all chronographs. It was in 1920 when Patek Philippe presented its first wristwatch chronometer with a rattrapante function right from the start. In 2009, when Patek Philippe presented the caliber CH 29-535 PS, its then latest proprietary chronograph movement based on classic principles —manually wound, column wheel, horizontal clutch—, it was already clear that some day, it would be followed by a caliber with the acronym CHR, which stands for CHronographe à Rattrapante —the French term for split-seconds chronograph.
