Eterna 1417: A Compact Marvel for Vintage Enthusiasts
The Eterna Calibre 1417 stands as a pinnacle of 1960s Swiss micro-engineering, captivating vintage watch enthusiasts and hobbyist watchmakers with its ultra-compact design. Introduced during Eterna’s innovative era of indirect-drive minutes, this manual-winding movement powered slim dress watches, offering precision in a 6 ligne (13.2mm diameter) package.
Historical Context
Eterna, founded in 1856, pioneered ball-bearing rotors and micro-rotor technology, but the 1417 exemplifies their pursuit of minimalism. Produced around the mid-1960s, it appeared in elegant time-only models from Eterna’s GranTurismo and Continental lines. Collectors prize it for reliability and the era’s hand-finished bridges, often with Geneva stripes.
