The P.9100/R is an automatic chronograph movement integrated with the countdown function, a crucial feature for regattas. The flyback chronograph with its vertical clutch and column wheel, allows users to track time before an event by pressing the push-button at 4 o’clock to set the countdown, with the minute hand moving back one minute per click. The START push-piece at 10 o’clock activates the chronograph hands, ensuring accurate timing from the start of the race for sailing.

* Essentially, Panerai uses the same Caliber P.9100/R flyback chronograph, vertical-clutch, 3-day-power-reserve movement found within its selection of regatta chronographs but reinterprets the sailing race start time countdown to one that’s suitable for military exercises. The countdown is programmed via the pusher at 4 o’clock, whereby each push adds 1 minute to the countdown.
