--- Introduction --- The Rado DiaStar is a landmark creation in the history of watchmaking, celebrated as one of the world's first scratchproof watches thanks to its pioneering use of hardmetal — a tungsten carbide composite of extraordinary hardness. This ladies' reference 133.9540.3 from the 1980s exemplifies the DiaStar's hallmark blend of technical innovation and aesthetic refinement. The tonneau-shaped black hardmetal case is paired with a black dial adorned with diamond hour markers and gold-tone arrow hands, set against a gold inner frame, creating a look of understated yet unmistakable luxury. The integrated hardmetal bracelet, signed with the Rado name on the fold-over clasp, completes the seamless, monolithic silhouette. --- Specifications --- Brand: Rado Series: DiaStar Reference: 133.9540.3 Movement: Quartz Case Material: Hardmetal (tungsten carbide, scratchproof) Crystal: Scratch-resistant mineral glass Dial: Black, diamond hour markers, gold-tone hands, gold inner frame, "RADO QUARTZ" and "DiaStar" text Case Back: Gold-tone screw-back, engraved "RADO 133.9540.3 SCRATCHPROOF WATERSEALED" Bracelet: Integrated hardmetal bracelet with Rado fold-over clasp Bracelet Length: Short (160–180 mm) Gender: Ladies' Period: 1980s Country of Origin: Switzerland --- Condition Report --- Overall: Good — quartz movement running, honest signs of wear appropriate to its age.
