Introduction

5370P
- Grand Complications
Manual winding

The split-seconds chronograph is one of the three most difficult complications to master, alongside the tourbillon and the minute repeater. It takes a highly sophisticated mechanism to control the two chronograph hands, one of which may be stopped to measure an intermediate or lap time or retain a reference time while the other continues its course unaffected, even by fractions of a second. When released again, the split-seconds hand instantly catches up with the primary hand and the two stacked hands move on together.

Press release

Patek Philippe Ref. 5370 split-seconds chronograph

For decades, split-seconds chronographs that allow lap times to be measured without interrupting an ongoing event time measurement have ranked among the most coveted Patek Philippe specialties. That was already the case in the 1920s, when the manufacture not only presented its first wristwatch chronometer but added the rattrapante function right from the start. Thus, collectors, aficionados, and enthusiasts of artisanally crafted timekeeping instruments are eager to welcome the new Ref. 5370 split-seconds chronograph. Not least because its elaborate inner life ticks beneath a genuine black enamel dial.
