Rado Watch DiaMaster Grande Seconde Plasma Ceramic. With its edgy yet retro design the Rado DiaMaster Grande Seconde is perfectly paired with a business suit or dressed down with casual weekend wear. The unconventional dial makes this timepiece, as well as the man wearing it, stand out. A watch to be worn with confidence, this is the ideal model for the man who dares to be different. Modern Alchemy. A brilliant warm metallic shine emerges from white ceramic when treated in a plasma oven where gasses activate at 20,000 C. This magical transformation is achieved thanks to a patented process first used by Rado. Without the use of any metal the unique plasma colour emerges from each piece of ceramic and will not fade over time. Although the colour only changes on the surface of the ceramic piece, it will not fade. With this process Rado is able to offer metallic looking watches with all the comfort of high tech ceramic. Scratch resistant, light and hypoallergenic, the benefits of high tech ceramic remain unaffected by the transformation. Be the master of your time with the Rado DiaMaster Grande Seconde.
