Return To ShopThe Eterna 1020S watch movement, produced between 1893-1895, was manufactured in 14,000 units. It featured a hunter calibre design, specifically the model 3. The movement incorporated a bimetallic screw balance and a ratchet positioned between plates. Additionally, it included a crown mechanism with a rocker bar, which effectively prevented unwanted hand movement during the switch from setting to winding.
