The Rado DiaMaster Petite Seconde Automatic COSC
The ‘Master of Materials’ label is one of which Rado is incredibly proud, and the quest for innovative combinations of materials continues as it strives to constantly chart new territory. Plasma high-tech ceramic is one such material whose use Rado pioneered and is a form of modern alchemy. The plasma carburising process allows the brand to create scratch-resistant high-tech ceramic with a metallic look without using metal. The colour won’t fade over time. Since it first appeared in 1998, it has become both a mainstay of the collection and inextricably linked with the Rado story - as well as playing a starring role on the case of the new 2018 DiaMaster Petite Seconde Automatic COSC. Only Rado has thought to combine scratch-resistant and durable plasma high-tech ceramic with a material known for its elasticity: silicon. It is this natural, light and hardwearing material placed at the heart of the new DiaMaster Petite Seconde in the form of the hairspring that has helped this new model achieve its enviable COSC certification for precision.
