5 split-second chronograph watches that will make you fall in love

Dive into the fascinating world of split-second chronographs, these horological marvels capable of measuring several times simultaneously. Discover 5 exceptional models that combine technical prowess and refined aesthetics, and that are likely to make your heart beat faster as a lover of fine watchmaking.

The split-seconds chronograph: a high-flying watch complication

Split-seconds chronographs, also known as rattrapante chronographs, represent the pinnacle of horological precision. These sophisticated watches feature two superimposed seconds hands, allowing multiple simultaneous events to be measured or split times to be timed without interrupting the main timekeeping.

The operation of a split-seconds chronograph is a true mechanical feat. The split-seconds hand, usually placed above or below the main chronograph hand, starts and stops at the same time as the latter. A special mechanism allows the split-seconds hand to be stopped independently to read an intermediate time, then to instantly “catch up” with the main hand in flight to resume its course.

This watch complication, long reserved for very high-end watches, has seen a resurgence of interest in recent years. More and more brands, from the most prestigious to the most accessible, are now integrating this function into their collections. Here is a selection of 5 remarkable split-seconds chronographs currently available on the market.

The FP Journe Chronographe Monopoussoir Rattrapante is a true watchmaking masterpiece presented at SIHH 2018. This watch is inspired by a unique model created for the Only Watch 2017 auction, which achieved the record sum of 1.15 million Swiss francs.

Technical characteristics :

  • 44 mm diameter titanium or platinum case
  • Hand-wound movement, caliber 1518
  • Single-pusher chronograph function with split-seconds
