P.5000 Movement

New Panerai 8-Day Power Reserve Calibre P.5000 Movement

It was only a few years ago that Officine Panerai introduced it’s first in house movement and took that leap into manufacture status. This year they again released a new movement known as the Calibre P.5000. This movement  is a manual wound movement with an amazing 8 day power reserve. The movement is going to make it’s debut in two new Panerai watches, the PAM 510 and the PAM 511

These days it’s hard to find a watch with an 8 day reserve, but Officine Panerai has had a long and rich history of creating watches with this eight day reserve. Since these watches were first introduced for the Navy Commandos of the Italian Navy, the eight day power reserve was a necessity for those long days in the trenches. The early Panerai watches featured an Angelus movement to achieve those specifications.

Keeping true to that heritage, the Panerai Calibre P.5000 is created with a mechanism that is contained between two plates, which conceal most of the wheels and allows very limited detail. The only things that you will notice being visible on this movement are the balance cock, intermediate wheel, and variable inertia balance. Using this variable inertia balance, it’s period of oscillation can be adjusted with little timing screws on the outside of the balance wheel. This makes the movement have a balance spring that is free, without the curb pins which normally would be used to modify it’s active length.

The bridge that supports the balance is fixed by two screws beneath which are threaded rings in both directions. The main purpose of this is to adjust the end shake of the balance staff pivots. Because of these advancements and design features it allows the movement to run perfectly even if there are shocks to the watch.

The Calibre P.5000 has a diameter  of 15.75 linges (35.7mm) and a thickness of 4.5 mm. It has 21 jewels and it is made up of 127 component parts with a balance wheel that will oscillate at a frequency of 3Hz. This frequency is equivalent to an amazing 21,600 vibrations/hour.
