Eterna 1476: A Vintage Manual-Wind Gem for Enthusiasts
The Eterna Caliber 1476, introduced around 1964, stands as a pinnacle of Swiss mid-century watchmaking, cherished by vintage collectors and hobbyist watchmakers for its robust construction and elegant finishing. This manual-wind movement, part of Eterna’s esteemed 1400-series, powers classic dress watches with reliable precision, evoking the golden era of horology when craftsmanship trumped mass production.
Historical Context
Launched during Eterna’s innovative 1960s phase, following their pioneering ball-bearing rotor automatics, the 1476 shifted focus to refined manual winding for slimmer profiles.
Produced into the late 1960s, it equipped models like NOS case references (e.g., 140T), often in 35-37mm stainless steel or gold-filled cases with signed crowns.
Appeals to restorers due to abundant spare parts availability and compatibility with period dials, making it ideal for bringing forgotten Eterna pieces back to life.
