1, the most expensive mechanical pen, priced at 700,000 RMB.

Richard Mille, the leading Swiss watch brand, made a pen across the border, and the price was as high as 700,000 RMB.

It took four years to build this pen. Equipped with RMS05 hollow titanium alloy movement, 18K platinum nib can be introduced.

The components of the device are made of five-grade titanium alloy, the bottom plate of the movement is treated by plasma, and the bridge plate is coated with PVD.

In this way, a unique pocket hollow extension device is formed, which has extremely high rigidity and a precise and flat surface.

2.RMS05: equipped with retractable escapement mechanism.

The pen holder is exclusively developed by Richard Mille: through the automatic decomposition system, the filaments between every two layers of carbon fibers rotate at a 45 angle; Hundreds of layers of carbon fibers are superimposed on each other, and finally a unique NTPT carbon material is formed.

The movement is equipped with retractable escapement and clockwork. This escapement mechanism is usually used for automatic chronograph watches. In the pen, press the trigger button at the end of the pen body.

Through a series of indescribable mechanical effects, the nib can be pushed out in a few seconds. When not in use, just cover the pen cap.

The mechanical device is triggered, and the spring springs up instantly, and the nib is retracted into the pen body.
