The Rado DiaStar Originals Collection, introduced in 1962, was created with the ambitious goal of developing a watch that would remain beautiful and functional for a lifetime. This was achieved through the innovation of Hardmetal—an ultra-durable tungsten carbide alloy—and sapphire-crystal glass, making it the world’s first truly scratchproof watch.

With its distinctive oval-shaped case, born from early machining limitations, the DiaStar became a hallmark of Rado’s mastery of materials. Its durability was famously demonstrated in marketing campaigns where participants attempted to scratch the watch with knives and nail files—unsuccessfully.

Over time, the collection expanded with various sizes, quartz options, and features like day-date complications

Rado launched the latest DiaStar Original models with:

• Polished Ceramos bezels

• Dials with a unique brushed grid texture

• Slender lume-filled hands and a vertical day-date display

These updated Originals maintain the legacy of the DiaStar—combining scratch resistance, timeless design, and versatility—ensuring their place as enduring icons in the watch world.
