Since Panerai's foundation, they have always upheld the spirit of researching and developing. To achieve consistent innovation, Panerai threw a lot of manpower and money. In 1938, with the professional technology that Panerai relied on to make the first group of professional diving watches for Italian Royal Navy, it first ranked among the watch-making industry, until now, Panerai has accumulated decades of experience in watch-making. Recently, Panerai upgraded its process again, introduced several kinds of in-house movements, which were entirely designed, developed and manufactured by Panerai's factory. "Calibre", in short, was a technical name of the movement, it was also the "engine" of the wrist watch and made it possible to display time. In technology, P.2005 was absolutely the most precise and complicated one among the four in-house movements of Panerai, that was exactly the movement Panerai used in Luminor 1950 Tourbillon GMT, which was a masterpiece that mixed long tradition and sports feature.
The biggest characteristic of the brand-new Luminor watch was its tourbillon. Tourbillon was invented by the great watchmaker Abraham-Louis Breguet in the end of the 18th century, this device was designed to eliminate the inaccuracy of the time, that was to avoid the faster or slower situation. Reasons that caused time inaccuracy included: the impact of gravity on balance wheel, deviation of the manufacturing process, oil condensate and the resulting friction between different positions of the watch. To eliminate time inaccuracy, Mr. Breguet made a constant rotating framework, which consisted of balance wheel, escapement device and some pivots. In this way, any inaccuracy which occurred when balance wheel traveled to a specific position could be eliminated. More than two centuries, tourbillon has always been the synonym of ultimate technology, it required the most high-precision processing technology. This technology was just used in watch-making industry in recent years, and the watch brands that adopted it were naturally the representatives of highest quality. Watch enthusiasts from generations to generation have been obsessed with the tourbillon escapement, which was a recognized technical challenge in watch-making industry. However, Panerai was not afraid of challenge, it even successfully made an innovation in this field and left its own mark in this advanced watch technology that has rarely changed since the invention.
Luminor 1950 Tourbillon GMT, its tourbillon rotated on axis that was in parallel with the base of the movement, rotating twice per minute. The time inaccuracy of the wrist watch was higher than the pocket watch because of the position, but the two innovation made this Panerai tourbillon better compensate for this deviation. P.2005 operated through a series of unique gearings that were similar to automotive differential gears, this was also one of the characteristics which P.2005 was different from other tourbillon watches. P.2005 had 239 components, manual winding, 3 barrels, it could supply 6-day power when being fully wound. Besides, Luminor 1950 Tourbillon GMT had GMT function, it used sapphire crystal glass face and see-through case back, so there was a panoramic view of the movement's operation through the case back, you could not only appreciate the charming appearance of the tourbillon, but the state of the power reserve could be read from the indicator.
This watch was highly distinctive, featured the unique crown guard that has been used by Luminor models for more than 60 years, polished and brushed stainless steel, 47mm in case diameter. It was water resistant to 100 metres, which fully met the standards of a navigation casual watch. The dial adopted sandwich structure and was protected by the antireflective sapphire crystal glass, 2mm thick. The middle layer of the dial was coated luminescent material, so the hour markers and Arabic numbers were particularly clear and readable even in the dark place. Hour and minute hands were large and wide, contrasted clearly with the slender arrow-shaped gmt hand, the gmt function was adjusted through the crown. Compared with the tourbillon watches of other watch brands, Luminor 1950 Tourbillon GMT didn't specially set a opening on the dial to show off this technical expertise, however, Panerai presented this feature in a distinctive way, the small detail at 9 o'clock, there was a blue dot indicator except the small seconds, its speed was two times the small seconds, 30 seconds per circle. The hand on another subdial at 3 turned a circle every 24 hours, the "pm" or "am" words told the wearer now was the day or night. The Panerai watch was fitted with alligator leather strap and Panerai personlised large brushed steel buckle, spare leather strap and the tools to replace the strap were also supplied.
