Copy Rattrapante chronographs, also referred to as split-seconds chronographs, are a type of chronograph with two seconds hands that allow for the ability to time multiple simultaneous events, such as runners during a race.
It can also time a series of events, such as the laps a single person makes on a track. One of the hands, the so-called “rattrapante” hand, sits either directly on top of or underneath the main chronograph hand. The Replica Watches hand is started and returns to zero simultaneously with the main chronograph hand.
IWC Portugieser Rattrapante Chronograph
IWC Replica introduced its first rattrapante chronograph to the Portugieser collection in 1995 when Richard Habring developed a split-seconds module for the iconic Valjoux 7750 movement.
It uses a push-button at 10 o’clock to control the movement of the upper hand, while the lower hand is managed by the pusher at 2 o’clock.
