--- Introduction --- The Rado DiaStar occupies a unique place in horological history as the world's first scratchproof watch, introduced in 1962. This vintage gentleman's example from the 1970s exemplifies the bold, futuristic design language of the era: a distinctive cushion-shaped hardmetal case with the characteristic satin-matte surface, housing an automatic movement with a convenient day-date complication. The dark charcoal-grey dial — with luminous applied bar indices, gold-tone hands, and Rado's iconic red-tipped sweep seconds — displays both the day (in English) and date through dual apertures at 6 o'clock. Presented on its original stainless steel integrated bracelet, this DiaStar is a compelling piece of 1970s watch design. --- Specifications --- Brand: Rado Series: DiaStar Reference: — Movement: Automatic with day-date Case Material: Hardmetal (tungsten carbide) — Rado scratchproof Crystal: Mineral Dial: Charcoal grey with luminous bar indices, gold-tone hands, day-date apertures at 6 o'clock Case Back: Stainless steel screw-back with Rado embossed star/seahorse motif Bracelet: Original stainless steel integrated link bracelet with fold-over clasp Bracelet Length: Regular (180-200 mm) Gender: Men Period: 1970s Country of Origin: Switzerland --- Condition Report --- Overall: Good — honest signs of wear commensurate with age Case & Bezel: Case surfaces show scratches and abrasion marks from decades of use; hardmetal retains its structural integrity Dial & Crystal: Dial shows light age-related spotting; crystal with minor surface scratches visible under direct light Bracelet & Clasp: Bracelet links show light surface scratches; clasp functions correctly Functions: Hours, minutes, seconds, day, date — movement running at time of listing --- International Shipping & Customs --- This watch ships internationally from Japan.
