DiaStar
Rado's founding line and the watch that established the brand's hardmetal identity. The original 1962 DiaStar was the first commercially available scratchproof watch, using tungsten carbide as the case and bracelet material. The 2021 DiaStar Original revival uses the same integrated hardmetal bracelet language — a unibody-look construction that predates the Royal Oak by a decade — with an ETA 2671 in a 38 mm case.
