Panerai P.2003 Calibre

side view of Automatic mechanical movement P.2003 calibre

This is, in fact, the first automatic movement developed entirely by Officine Panerai, as this brand continues to innovate and  improve the, buy now, rather big panoply of self designed and manufactured calibres.

It is the descendant of the P.2002 calibre, inheriting all its functions but taking one step further and providing a 10 days power reserve,  displayed on the dial by a linear indicator. So this essential technical feature was improved up to the amazing 10 days level, possible due to the three mains-spring barrels that accumulate 240 h of power when fully wound. Two of the spring barrels are positioned one on top of the other and the third one is linked to the other two through a gear train.  This way, the remaining power can be indicated on the graduate scale. The winding is automatic and bi-directional.

Beside the basic function of simple time measurement (hours and minutes), the GMT function becomes handy for those who are traveling a lot. A second central-mounted hand assures GMT reading in a 24 hours format and the seconds sub-dial has a AM/PM indicator in order to eliminate any possible confusion.

The seconds reset is a beautiful feature that engages a complicated mechanism of levers, heart-shaped cam and some blades in order to stop the small seconds hand and reset it to zero.

Another unique and useful offering is the fact that this calibre lets you  switch the hour in a 1 h jumps forward or backwards (the quick hour-hand correction feature) without moving the minute hand. The date will adjust automatically.

All the structural parts of this mechanism have polished screws and edges while the oscillating weight also bears the logo of the brand.

With its 13 3/4 lignes 25 jewels and 8 mm thickness, this is a large calibre. In total it counts 281 components and you will find it in all the variations of the Radiomir 10 Days GMT Automatic models and in the Luminor 1950 10 Days Automatic GMT ones, all big case watches, ranging from 44mm up to 47 mm. And although you may expect that all the features provided by this calibre would have as a result a rather busy dial, you will be surprised in the most pleasant way to observe that the dials have a clear design in order to give a friendly experience to the users.

The P.2003 calibre also has a variation in the form of the P.2003/10 calibre, slightly different, counting 293 parts and offering a higher level of skeletonization on the oscillating weight, bridges and barrels. The finishing on this calibre is truly exceptional and can be compared to the one that you can find at watches from Audemars Piguet or Vacheron Constantin. The P.2003/10 calibre is the beating heart of the model Radiomir 1940 10 Days GMT Automatic Oro Rosso.

Calibre`s P.2003 features and complications are the proof that the company’s portfolio is getting more and more divers, as Officine Panerai wish to offer to its customers a cutting-edge technology completely developed in its high-standard obeying laboratories.
