Eterna - "Concept 80" - Senza prezzo di riserva - Unisex - 1970-1979

For true connoisseurs of horological anomalies and high-end Swiss independent watchmaking, this is a spectacular and near-mythical variant of the famous Eterna Concept 80 line from the early 1970s.While 99% of the Concept 80 production featured the ubiquitous automatic "Eterna-Matic" movements, this specific timepiece represents a magnificent chronometric paradox: a pure, minimalist dial bearing only the "ETERNA" manufacture name, entirely unburdened by the "Matic" script, yet extraordinarily complemented by a Date complication at 3 o'clock.The Mechanical Masterpiece:Beneath the dial beats a rare, high-grade Eterna Manual Winding Manufacture Caliber with Date. In the 1970s, creating a manual watch with a calendar disk required an independent architectural movement that was produced in microscopic quantities compared to mass-produced automatics. The non-quickset date progression is a masterclass in traditional micro-engineering, working exactly as it did when it left the Grenchen workshops over 50 years ago. This specific mechanical configuration makes the watch a ghost on the market—virtually undocumented in standard commercial catalogs.Uncompromising Originality & Provenance:This specimen is a true time capsule, preserving two critical features that exponentially increase its collector value:The Dial & Case: A stunning, untouched silver sunburst dial with sharp applied markers, housed in the iconic, unpolished космический (space-age) cushion case.The Crown: The highly coveted, original crown proudly featuring the 5-dot Eterna relief logo, proving it has never been replaced during generic servicing.The Bracelet: A premium, period-correct Milanese mesh bracelet crafted in Pforzheim by the legendary German master-manufacture Fischer & Cie., providing an incredibly luxurious drape on the wrist and an imposing vintage presence.An absolute grail watch for any serious Eterna or vintage Swiss watch collector looking for a piece that simply cannot be found anywhere else.Brand: EternaModel: Concept 80 (Ultra-Rare Manual Winding Variant)Functions: Hours, Minutes, Seconds, Date at 3 o'clockMovement: Swiss Mechanical Manual-Winding Manufacture CaliberCondition: Excellent vintage condition, fully functional, beautifully preserved.
