Profoundly changed in appearance, the Luminor Tourbillon GMT – Lo Scienziato already forceful personality is now highlighted by a Grade 5 titanium case, with a sandblasted finish and a steeper gradient. Its impact is enhanced by the visual contrast it makes with the bezel, the crown and the lever of the crown-protecting Safety Lock™ device which are made of carbotech. Contrasting with this monochrome spectrum, the military green dial plays an important role. Attracting the eye is the flange encircling the floating numerals, the small-seconds dial, the 24-hour counter and the power reserve indicator.
The amazing Luminor Tourbillon GMT is the natural result of the most advanced technologies. Its 47-mm case is made of Grade 5 titanium, a remarkable material because it is polyvalent and tough, has high resistance to corrosion, and is at the same time 40% lighter than steel. But what makes it unique is not so much the physical properties of the metal as the way in which it is created, using 3D printing with Direct Metal Laser Sintering (DMLS). Layer by layer, titanium powder is consolidated by high power fibre optic laser sintering, thus becoming a solid material and forming a shape from nothing. In this process of precision sedimentation, each pass of the laser generates an imperceptible but constant addition, 20 microns (0.02 mm) thick, but most importantly it enables a caseband to be formed which is hollow inside, reducing its weight to a record 18 grams without reducing its strength or water-resistance.
The powerful identity of the Luminor Tourbillon GMT is immediately and unequivocally conveyed by the P.2005/T calibre within it. A hand-wound mechanical Manufacture movement with GMT function, introduced by Panerai for the first time in 2016, it stands out for its unusual, innovative structure. The result is a minimalist design with an original, modern approach, including its three spring barrels mounted in series (patented) which provide a power reserve of six days. It too is entirely made of titanium; this has helped to restrict its weight to just 23 grams. It relies for its performance on a tourbillon device with a cage designed to rotate – once every 30 seconds instead of the traditional 60 seconds – on an axis which is perpendicular to that of the balance wheel. This inspired design, developed to compensate for the effects of gravity on the regulator, results in more even running. The movement has now been further developed to display the power reserve indicator on the front of the watch for the first time.
