This Eterna‑Matic dates to 1963 and exemplifies mid‑century restraint with a 34 mm stainless steel case and an understated dial under an acrylic crystal. The watch houses Caliber 1422, a 21‑jewel automatic movement that continues Eterna’s legacy of rotor efficiency established with its ball‑bearing system. Its proportions and period details make it a clear example of functional, finely made Swiss watchmaking of the era. For a contemporary collector seeking a compact, historically informed automatic, it offers a direct connection to Eterna’s technical traditions and everyday wearable design.
