Functions in depth

The split-seconds function, also known as Rattrapante, operates two hands that are superimposed and partially independent: the first is entirely controlled by the push-piece at 8 o’clock, which starts, stops and resets the chronograph hand; the second, controlled by the push-piece at 10 o’clock, is used for measuring partial times or a second event simultaneous with the first. To make it easier and clearer to read, the hand of the small minute counter moves in jumps instead of continuously.

  • +

    One press on the «START»

    push-piece at 8 o’clock automatically activates the chronograph hands.

  • +

    One press on the «RATTRAPANTE»

    push-piece at 10 o’clock stops and the split-seconds hand while the rhodium seconds hand and the minutes hands continue to move, indicating the intermediate time related to the event.

  • +

    One further press on the «RATTRAPANTE»

    push-piece causes the split-seconds hand to rejoin the chronograph seconds hand so that they are in unison.

The column wheel

The column wheel

The Panerai Chronograph movements feature a column wheel system, a sophisticated mechanism that guarantees the highest standards in terms of technology, quality and reliability.
The column wheel takes its name from the presence of a series of “columns” positioned perpendicularly above the wheel. Its function is to control (activate/deactivate) the chronograph levers according to the impulses received by the chrono push-piece.
These columns guide the movement of the chronograph levers which press against a column or fall into an empty space. The column wheel therefore permits two or more levers to be engaged simultaneously, which operate the chronograph functions with a single push.
This device therefore allows greater precision in the operational sequences of the chronograph. The column wheel ensures smoother operation of the chronograph and very precise operation of the chronograph functions.
The column wheel is visible on the back of the watch through the sapphire crystal window.

The vertical clutch

The vertical clutch

This sophisticated system permits the simultaneous transmission of energy between the movement and the chronograph functions. The system is composed of three parts: the lower seconds wheel rotates constantly since it is connected to the seconds wheel of the movement; the chrono seconds wheel is positioned above the latter and a ange which permits the connection/ disconnection between these two wheels. When the chronograph is engaged, the ange comes down and places the lower seconds wheel in contact with the chrono seconds wheel which starts to turn (chrono on). Since the ange is a system without teeth, the vertical clutch prevents the second hand from jumping when the chronograph is engaged. In chronographs with a lateral clutch, the engaging movement causes a shift which may result in the chronograph hand making a larger jump than normal. Furthermore the vertical clutch reduces the effects that the engagement has on the balance amplitude and the chronograph can continue working for longer without negative effects on the accuracy of the watch.
