Introduced by Officine Panerai in 2016 as the first implementation in watchmaking of another 3D printing technique used to create its case, the exclusive Lo Scienziato Luminor 1950 Tourbillon GMT is currently available in another version which maintains the vital highlights of its archetype however with a slightly revised appearance.
In the new model the blue of the hands, harmonizing with the metallic tones of the titanium case, is likewise utilized on the spine and in the sewing of the dark cowhide lash, enhancing the lively appearance of this super-technological timepiece.
The Luminor 1950 case has the classic diameter of 47 mm and it is made of titanium, a material that is resistant to corrosion yet additionally about 40% lighter than steel. To decrease the weight further, the case is made using an innovative technology which empowers complex geometrical shapes to be made without in any manner compromising its water-resistance (10 bar, equivalent to a profundity of around 100 meters/330 feet), its solidity or its resistance to any tension or torsion to which the case might be oppressed.
The technology utilized is called Direct Metal Laser Sintering: this cycle builds up a 3D item layer by layer by methods for a fiber optic laser using powdered titanium. The successive layers – every one just 0.02 mm thick – combine and become completely solid, creating structures which would be impossible to achieve using traditional working strategies, lower in weight and with a uniform, even appearance.
What’s more, without a doubt, the lightness of the new Lo Scienziato is really noteworthy, especially if you consider the rich arrangement of highlights: hours, minutes, little seconds, GMT with am/pm indication, an influence hold of six days with indication of the influence remaining on the back, and a tourbillon escapement.
The hand-wound P.2005 mechanical development shows up here in the P.2005/T version, skeletonised and with titanium bridges and plates. Beating at 28,800 vibrations each hour, this high level development ensures a force hold of 144 hours (6 days).
Because of the lower density of this material – about a large portion of that of the metal of which these components are regularly made – the general weight of the development is 35% not exactly that of the P.2005/S skeletonised version.
The ultimate lightness of the watch is both the aftereffect of the fine skeletonising of the bridges, plates and spring barrels, and of the shortfall of a traditional dial, since all the components which regularly comprise it are joined directly to the development or the spine of the watch, like the hour markers.
At 9 o’clock is the little seconds dial, inside which a little indicator pivots, showing the rotation of the tourbillon. At 3 o’clock, another little dial indicates whether the focal second time zone hand (GMT) alludes to day or night. The long force hold of six days is achieved by the three spring barrels associated in series, and the force remaining is appeared by a special indicator on the rear of the development, visible through the enormous sapphire gem opening on the rear of the watch.
The rotation of the tourbillon enclosure can be admired from the two sides of the watch. Interestingly, it turns on an axis which is perpendicular, not resemble, to that of the equilibrium, and it makes a complete rotation like clockwork instead of once every minute. This way, it compensates all the more precisely for the impacts of gravity on the escapement, consequently further enhancing exactness.
