PATEK PHILIPPE – Split-Seconds Chronograph Ref. 5370

As a mechanism that measures intermediate times while continuing to time an ongoing interval, the split-seconds chronograph has long been, for collectors, one of the most coveted among Patek Philippe’s specialities. The new Ref. 5370 marks the debut of the CHR 29-535 PS calibre in its purest form, with no additional complications. It also introduces a “double time” device, namely two pushers for the basic chronograph functions and a pusher in the crown to start and stop the split-seconds hand. While celebrating tradition with its architecture, manual winding, two column wheels and horizontal clutch, this is very much a chronograph for the twenty-first century, thanks to the many patented optimisations. The sumptuous black enamel dial promises perfect legibility, enhanced by the platinum case. The prestigious Patek Philippe Seal crowns the whole.
