Some technical press on it.

 

The power reserve of 8 days, tested by Panerai at the end of the 1940s, has been repeated in the Panerai movement by using an assembly consisting of three spring barrels. To achieve accurate setting of the hands and synchronization with the reference time signal, the seconds hand jumps to zero as a result of the zero reset device, a sophisticated zeroing system which at the same time instantly stops the balance wheel. Avant-garde techniques are employed in the construction of the movement. This is hand-wound and consists of 245 components, with a free-spring balance and no conventional regulator. This means that a very precise regulation can be carried out by adjusting the screws directly on the balance wheel itself.

The Luminor 1950 8 Days GMT's black cushion dial (formed of two superimposed plates, the upper one being perforated and the lower one covered with luminous material) has a small calendar window at 3 o'clock, symmetrically complemented by the traditional continuous seconds dial. The power reserve indication, employing a triangular index which moves across a graduated linear scale, is at 6 o'clock, while the arrow-pointed centre hand of the second time zone is partnered by the day/night subdivision, visible through the circular aperture at 9 o'clock, which through its different colors enables the hours before and after midday to be distinguished.
