A rare 1970s Swiss-made model with a sapphire crystal. Size: 36×40mm, 18mm lug width, ETA 2824 movement. Overhauled on November 15, 2024: parts cleaned, epilame treatment applied, lubricated with high-quality Swiss-made oils and greases. Accuracy: ±5 seconds/day on a timegrapher (measured with the watch positioned face-up). ±15 seconds in daily use. Accuracy may vary more than in a modern watch due to its age. Light polishing removed minor scratches, but deep scratches and dents remain. The crystal has light scratches. Case back and crown gaskets replaced; silicone grease applied for water resistance. Rado logo does not rotate. Fitted with a Seiko new leather strap.
