History 
Since the beginning, Rado has not only concentrated on developing beautiful watches – the factor of material has always been at the forefront too. The aim has been, and still is, to create watches that are beautiful and that stay beautiful. Watches that are not made from gold, brass or steel, as in conventional watch manufacture, but from innovative materials like high-tech diamond, sapphire crystal, hardmetal or high-tech ceramics. Materials with much more than just average resistance, a unique brilliance and – of course – the legendary Rado scratchproofness.
