A chronograph is known to most people as a watch. However, most people don’t know what it is and its different types. This entry will tell you everything you need about them. Moreover, we advise you why it has been one of the most beloved wristwatches for centuries.

What Is Chronograph?

The chronograph is a complication that describes the timing functionality of a watch, more commonly known as a stopwatch. This feature allows for interval measurements to be made without affecting the watch’s standard time-telling capability. Chronographs changed the world because they provided unprecedented accuracy in measuring time – to within 1/100 of a second. In today’s watches, there are three types:

  • Simple Chronograph
  • Rattrapante Chronograph
  • Flyback Chronograph

But in this article, we will discuss Rattrapante & Flyback Chronograph.

What Is Rattrapante Chronograph

A rattrapante clock, also known as the split-seconds chronograph, consists of two seconds hands that allow multiple simultaneous events, such as racing, to be timed simultaneously. Also, it can record the number of laps a person makes on a track. It sits either directly on top of or beneath the central chronograph hand, known as the “rattrapante” hand. Both the rattrapante hand and main chronograph hand start and return to zero simultaneously. Using a special push-piece and an additional mechanism, it can repeatedly stop (for reading split times) and then instantly brought back into synchrony with the central chronograph hand by flying around to catch up with it.

All of this occurs without affecting the central chronograph hand (Rattrapante is French for “to catch again.”) With more and more brands of all sizes, including the split-second chronograph in their offerings over the years, we have seen the complication trend upwards. Even though it’s highly coveted, the rattrapante chronograph is not categorized as a Grand Complication. Nevertheless, it is an incredible work of brilliant design and precise implementation. For those looking to purchase a rattrapante chronograph from IWC Schaffhausen (dubbed a double chronograph), Patek Philippe, A. Lange & Söhne, or Breitling will have to dig deep into their pocket and shell out a lot of cash.

What Is Flyback Chronograph

Longines introduced the flyback function with their movement 13ZN in 1936: The second pusher at 4 o’clock, which usually activates the clock reset when it stopped via the pusher at 2 o’clock be used at any time. Activation of this pusher causes the stopwatch to reset when it has been stopped. As the reset button is pressed and held while running, an initial reset occurs, and the clock starts over from scratch. By utilizing this ingenious functionality, a new measurement period can begin within milliseconds. One has to lift one’s finger from the reset pusher to synchronize the subsequent measurement with an event or signal very precisely and without a large margin of error. To implement the flyback function, they must modify movement. It cannot be reset while running because the hammers that strike the heart-shaped cams on the hands can cause damage if it hasn’t been decoupled. The flyback chronograph achieves this decoupling during reset, though only for a moment. There is a separate lever that is used to initiate the decoupling.
