Eterna Caliber 880: A Vintage Powerhouse for Enthusiasts
The Eterna Caliber 880 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 manual-wind movement powered numerous Eterna dress watches and chronometers, embodying the brand’s legacy of precision engineering post their iconic ball-bearing rotor innovations.
