The bold headline — 'The Defeat of the Great Watch Killer' — dramatizes Eterna's patented five-ball-bearing rotor system, invented in 1948, which virtually eliminated rotor friction and revolutionized self-winding movement design. The magazine advertisement showcases the Eterna-Matic 3000 Dato alongside a spilled thimble of miniature ball bearings and an exposed movement, making this collectible ad as much a horological document as it is a design artifact. A compelling find for Swiss watch enthusiasts and mid-century collectors alike.\u003c\/p\u003e\n\u003c!-- Source: Watches | Seller: Rob | File: watches.other.7.27.26b-0056.jpg | Collections: Watches --\u003e","brand":"Rob","offers":[{"title":"No Frame","offer_id":58555855732896,"sku":"ETE-WAT-1965-001","price":25.0,"currency_code":"USD","in_stock":true},{"title":"Custom","offer_id":58583385342112,"sku":null,"price":225.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1035\/5726\/7616\/files\/watches.other.7.27.26b-0056_48fb55b7-8aa3-4189-a993-cd3f3e833688.jpg?v=1785201746","url":"https:\/\/adsforlegends.com\/products\/vintage-1960s-eterna-matic-3000-dato-print-advertisement-original-swiss-automati","provider":"Ads For Legends","version":"1.0","type":"link"}
