Age Estimate
Circa 1965-1970 based on the logo style, dial crosshairs, and the shift from radium to tritium (though likely non-luminous).
Cultural Significance
Represents the standard mechanical precision of the German middle class before the Quartz Crisis. It bridges the gap between utilitarianism and luxury style.
Condition Notes
Fair to Good. Significant scratching on the acrylic crystal; visible plating wear (rub-through) on the edges of the lugs; dial appears remarkably clean with no major oxidation; missing strap.
Value Estimate
Secondary market: $150 - $350 USD depending on movement health and case plating integrity.
Care & Maintenance
Requires manual winding every 24 hours. Given the age, it should be kept away from all water exposure. The acrylic crystal can be polished with Polywatch to remove surface scratches.
