The Luminor 1950 Tourbillon GMT is equipped with the Calibre P.2005, a movement with a tourbillon escapement, the greatest technical expression of mechanical horology: a complication notable for the difficulty of its construction and the accomplishment of which is the result of the outstanding craftsmanship of master horologists and the most advanced electronic technology. The special feature of the regulating organ perfected by Panerai lies in the fact that the tourbillon cage rotates on an axis at right angles to the axis of the balance wheel and that it makes two rotations per minute: this rotation, which is faster than usual, ensures greater accuracy, providing the best compensation for the irregular rate caused by the effect of the force of gravity. The fascinating motion of the tourbillon, which attracts the attention of everyone who looks at it, can be admired from the back of the watch, while on the dial side there is a little circular blue indicator, within the seconds counter at 9 o’clock, which travels twice as quickly as the seconds hand because it moves at the speed of the tourbillon cage.
