Up for auction is a sophisticated Eterna-Matic 1000, a watch that represents the pinnacle of 1960s technical innovation. Eterna is world-renowned for inventing the ball-bearing supported rotor, a technology so successful it became the foundation for the five-dot logo seen on the dial and original crown of this very watch. The Dial: The watch features a stunning silver "Concept" dial with a subtle sunburst texture. It is elegantly appointed with applied baton indices and matching steel hands. The dial is exceptionally clean, preserving the minimalist luxury aesthetic that Eterna is famous for. The Case & Movement: • Movement: High-grade Swiss Automatic movement featuring the iconic ball-bearing rotor. It is a robust, high-frequency caliber designed for daily reliability.  • Case: Sharp stainless steel case with a screw-down back. The lugs are crisp, suggesting the watch has been well-cared for over the decades. • Crown: Original signed Eterna crown featuring the five-dot logo. Condition Report • Movement: The watch is running accurately and strong. Please note the specific functionality of the date: while the manual date advancement (through turning the hands) and the midnight transition work perfectly, the "pull-crown" quickset function is intermittent. • Service History: The service history is unknown; a routine service is recommended for long-term daily wear. • Dial & Hands: Excellent, near-mint condition. The markers and hands retain a high polish with no significant oxidation. • Case: Very good vintage condition with light surface scratches consistent with careful use. No deep gouges or significant dings. • Strap: Fitted with a new, premium black leather strap that perfectly complements the steel case.
