The Panerai caliber P.5000 is a handwound mechanical watch movement with 21 jewels and a frequency of 3 Hz (21,600 beats per hour). This calibre is equipped with double mainspring barrels, allowing for a power reserve of up to 8 days on a full wind. The P.5000 is a true no-date movement. Panerai announced watched with this movement in 2013.

The design is inspired by vintage pocket watch movements.

Panerai Caliber P5000 Bridge Removed

In Panerai’s own words:

A power reserve of eight days and hand-wound: the P.5000 calibre combines these two characteristics which are part of the history of Panerai watches since the first models created for the commandos of the Italian Navy. With a diameter of 15¾ lignes (35.7 mm) and a thickness of 4.5 mm, the P.5000 calibre has 21 jewels, it is made up of 127 component parts and its balance wheel oscillates at a frequency of 3 Hz, equivalent to 21,600 vibrations/hour. Its original, very strong structure recalls that of old movements in which the mechanism was contained between two plates concealing most of the wheels and allowing only a few details to be seen, such as the balance cock and the intermediate wheel.

The P.5000 calibre has a variable inertia balance, its period of oscillation being adjusted by turning the little timing screws on the outside of the balance wheel. Using this system the balance spring is free, without the curb pins which would otherwise be used to modify its active length. The bridge supporting the balance is fixed by two screws beneath which are threaded rings which turn in both directions, the purpose of which is to adjust the endshake of the balance staff pivots. This technical solution helps the escapement to continue running perfectly in the event of shocks.

The long power reserve of 192 hours, that is 8 days, is achieved by coupling the two spring barrels with toothed rims in series. The twin assembly enables longer, thinner springs to be used, resulting in a longer duration and greater uniformity in delivering energy to the movement.” -Source: YouTube video description (video below)

Does Caliber P.5000 Have Hacking Seconds?

When the Panerai P.5000 was introduced, it was not engineering for hacking seconds – aka the seconds hand did not stop when the crown was pulled to time-setting mode. Around 2018 with the updated version of the P.5000, Panerai started to include a stop-seconds lever for hacking seconds functionality.

Anti-Shock Device:

On the Panerai website here, they state that the P.5000 has an “Incabloc Parechoc® anti-shock device.”

This is incorrect, since Incabloc is one company and Kif Parachoc is another. The shock-absorber in the cal. P.5000 is a Kif.
