The Eterna Caliber 1079 stands as a hallmark of mid-20th-century Swiss horology, cherished by vintage watch enthusiasts and hobbyist watchmakers for its robust construction and timeless reliability. Produced primarily in the 1940s, this manual-wind movement powered elegant dress watches during the post-war era, embodying Eterna’s precision engineering heritage.
Historical Context
Introduced around 1944-1947, the 1079 emerged from Eterna’s Granville facility as a refined evolution of smaller calibers like the 1078. It equipped stainless steel cases typical of the period, often measuring 35mm in diameter with 16-18mm lug widths. Collectors prize serviced examples for their smooth sweeping seconds hand and durable components, ideal for restoration projects.
