Exploring the Eterna Caliber 1324: A Vintage Gem for Enthusiasts
The Eterna Caliber 1324 stands as a testament to mid-20th-century Swiss horological ingenuity, cherished by vintage watch collectors and hobbyist watchmakers for its robust construction and reliable performance. Produced primarily in the 1960s and 1970s, this automatic movement powered numerous Eterna models, blending self-winding efficiency with timeless mechanical elegance. Its design reflects Eterna’s pioneering spirit in rotor technology, making it a favorite for restoration projects.
Historical Context
Introduced during Eterna’s golden era of innovation, the 1324 evolved from earlier self-winding calibers, incorporating lessons from the brand’s ball-bearing rotor patents. It appeared in dress watches and sports models, often paired with exhibition casebacks to showcase its finishing. Vintage examples today command attention at auctions, valued for their serviceability and parts availability through specialist suppliers.
