The model with the blue dial reveals a metallic shine on the case and bracelet, indicating that in this case the Rado designers polished the high-tech ceramic surface using a process called plasma cementation.

Through the sapphire crystal case back, we can also view the mechanical movement, which stores enough energy for 80 hours of operation. The metal surfaces are adorned with Côtes de Genève and perlage decorations, bringing centuries-old watchmaking traditions into the most modern watch case.

The ends of the plasma high-tech ceramic bracelet are secured on the wrist with a titanium folding clasp.

The high-tech ceramic is highly resistant to potential scratches, does not fade, is hypoallergenic, and quickly adapts to body temperature, making it extremely comfortable to wear.
