--- Introduction --- This Rado Coupole, reference 129.4077.4, is a graceful expression of the avant-garde design language that made the Swiss house famous. Its faceted sapphire crystal sweeps across the full width of the case, creating a seamless, mirror-like surface in deep black with shifting blue reflections. Fine gold-tone hands and minimalist dot markers float above the black dial, while a discreet date window at 6 o'clock preserves the purity of the composition. Sculptural gold-tone lug fittings and a signed gold-tone buckle lend a refined warmth to this distinctive vintage piece. --- Specifications --- Brand: Rado Series: Coupole Reference: 129.4077.4 N Movement: Quartz Case Material: Stainless steel with gold-tone crown and lug fittings Crystal: Faceted sapphire crystal Dial: Black with gold-tone dot markers, gold-tone hands and date window at 6 o'clock Case Back: Stainless steel, engraved with the Rado name, reference, "Sapphire Crystal" and "Watersealed" Bracelet: Black leather strap, stamped Rado Swiss Made, with signed gold-tone pin buckle Period: 1990s (estimated) Country of Origin: Switzerland --- Condition Report --- Overall: Good pre-owned vintage condition, with visible signs of age and use consistent with regular wear.
