Radiomir 1940 3 Days Automatic ORO ROSSO (3 day power reserve automatic red gold watch) reproduces the design of many historical watches created by Panerai around 1940; its diameter is 45 mm, Made of 5NPt red gold, this alloy contains a higher proportion of copper and a small amount of platinum, which helps reduce metal oxidation. The lugs and case are made of the same piece of metal and fit perfectly with the curve of the wrist to ensure a comfortable experience when wearing the watch. The polished large bezel surrounds the classic dial with excellent readability. Its design is extremely simple. The structure formed by the overlapping discs contains luminous materials, making the hour and bar marks in the upper disc clear and legible. In design, it inherits the tradition of Panerai since the late 1940s. The small second hand rotates in the small dial of the brown dial at 9 o’clock.
The new P.4000 movement is Panerai’s first self-winding movement with an eccentric rotor. This means that the diameter of the rotor is smaller than the movement itself: this sophisticated technology makes the movement and the watch as a whole thinner. In this model, the oscillating weight is made of tungsten. This shiny high-density metal has excellent characteristics. It is very aesthetically pleasing in appearance, and it is very suitable for places where high specific gravity materials are required. Set next to the rotor is a balance wheel, which swings constantly at a frequency of 4 Hz. Most of this mechanism is covered by a large splint, making the movement structure more robust and stable. The P.4000 movement is equipped with two barrels in series, with a power reserve of at least 3 days. In addition, the movement is equipped with a special device that can stop the vibration of the balance wheel when the crown is pulled out to adjust the time, helping the wearer to accurately synchronize the time.
The Radiomir 1940 3 Days Automatic Oro Rosso watch is water-resistant to 5 bar (about 50 meters) and comes with a brown alligator leather strap.
