Title: Eterna Concept 80 – Ref. 456 T – "TV-Screen" Cushion Case – Circa 1970 Description: An exceptional example of 1970s Swiss avant-garde design, this Eterna Concept 80 captures the bold, geometric aesthetic of the era. Featuring a "TV-screen" cushion case with a striking sunburst finish, this piece is a perfect blend of vintage character and high-quality Swiss watchmaking. Condition Report: • Dial: Excellent vintage condition. The champagne/silver sunburst dial is remarkably clean, showing no significant oxidation or spotting—rare for a watch of this age. • Case: Original gold-plated case with sharp edges and the original factory brushing intact on the top surface. Light surface "swirls" consistent with careful use. • Movement: High-grade Swiss manual-wind movement, signed Eterna.
