Eterna-Matic – Vintage Automatic – 10K Gold Filled Case – 34 mm – Swiss Mechanical – Classic 1950s Design A refined and highly collectible Eterna-Matic automatic wristwatch, representing one of the most important milestones in Swiss watchmaking history. Eterna is the manufacture behind the revolutionary ball-bearing rotor system introduced in 1948 — a technical breakthrough that defined modern automatic movements and remains influential to this day. This elegant example features a 34 mm 10K gold filled case with beautifully sculpted lugs and classic mid-century proportions. The warm tone of the gold filled case has developed a gentle vintage character over time, with visible signs of wear consistent with age. The case lines remain well preserved, offering authentic 1950s wrist presence. The silver dial displays a charming two-tone construction with a recessed inner circle and applied golden Arabic numerals at 12, 2, 4, 6, 8 and 10. The applied golden baton hour markers complete the layout, while the dauphine-style gold hands provide elegant contrast. The “Eterna-Matic” signature sits cleanly beneath the applied five-ball logo — a reference to the brand’s famous ball-bearing rotor innovation. The dial shows light patina and aging consistent with its period, enhancing its authenticity and vintage appeal. The watch is powered by a Swiss mechanical automatic movement, reflecting Eterna’s historical expertise in self-winding calibers. It is currently functioning; water resistance has not been tested due to age. It is fitted with a generic black leather strap that can accommodate a wrist up to approximately 20 cm. The acrylic crystal shows light surface marks consistent with normal use.
