Panerai P.2004 calibre

Manually winded p.2004 movement front

This calibre is another success in the long line of technological achievements of the Neuchatel brand when it comes to designing and  developing its calibres. The P.2004 calibre is, in fact, the first chronograph movement created entirely by Panerai. A complete movement that offers the simple time measurement tools (hours and minutes) but adds complicated features like the small seconds, GMT, the 8 days power reserve linear indicator and the seconds reset. And on top of all these, it is also a single button chronograph.

This hand-wound mechanical movement has 13 3/4 lignes, 29 jewels and it’s 8.2 mm thick. It counts 321 components in total and it works with a frequency of 28,800 alternations/hour fitted with a regulating screw.

As a successor of the P.2003 calibre, all the features are kept. The second time zone with the day/night indicator (a little window from the small seconds dial turns from white into black, making the difference between AM/PM time zone), the amount of running time remaining showed by the linear indicator on the dial, the zeroing of the seconds hand in order to synchronize the watch- you just need to pull the winding crown and the small seconds hand returns to zero and stops. But the best part is the chronograph function, that has a cool particularity of having just one push-piece (located, at the level of the dial, at 8 o’clock position) instead of two, like most chronograph have. This push-piece, when pressed in sequence, starts/stops and zeroes the central hand with great precision due to the column wheel. This chronograph function does the job through a friction clutch, an important detail that forbids the movement of the hand to be unsteady. The minute counter moves instantaneously by  clicking from one position to the next on the 60th second of each minute.

All the functions along with the  8 days power reserve are possible through three superimposed spring barrels that sore lots of energy.

The design of this movement is cut out for all the functions provided: chamfered and polished angles, large brushed plates, mirror-polished screws, separate bridges.

The P.2004 has the P.2004/10 as a variation, executing the same functions but with a more sophisticated look in therms of finishing, as the three-quarter plate and barrel are skeletonised.

The P.2004 calibre is obviously equipped with  Glucydur balance and a Parechoc anti-shock device and it also provides a water resistance up to 100 m.

Large calibre also means large cases, so the P.2004 can be found inside the Luminor 1950 Chrono Monopulsante GMT & 8 Days models in all variations (including the Left-Handed one), with a diameter ranging from 44 mm to 47 mm.

Aiming constantly to expand the range of their in-house produced calibres, Officine Panerai`s offers a unique high-tech approach that, blended with their signature case design, is providing original and valuable luxury wrist watches.
