 [[ETA]] was one of the three firms "chosen" to develop advanced [[automatic]] watch movements by [[Ebauches SA]], thanks in part to their history with [[Eterna]]. The chief designer at ETA, [[Heinrich Stamm]], had created many of the company's important watch movements, and was famous for the [[Eterna-Matic]] line of watches. For the 1960's, Eterna wanted to develop an [[ultra-thin]] successor to their successful Eterna-Matic "Centenaire" line and Stamm took up the challenge. [[ETA]] was one of the three firms "chosen" to develop advanced [[automatic]] watch movements by [[Ebauches SA]], thanks in part to their history with [[Eterna]].

-The result was Cal. 1466 and the related family of movements. Measuring just 3.6 mm high, despite a [[central rotor]] winding system, Cal. 1466 made the ultra-thin [[Eterna-Matic 3000]] possible. It was essentially an all-new movement unrelated to the previous [[Eterna 1438|Cal. 1438]] and contemporary [[Eterna 1470|Cal. 1470. This family featured a direct seconds drive, a major modernization, and is much thinner than any previous movement. Common to Stamm's designs, Cal. 1466 features "Eterna" gear tooth profile and un-spring winding ratchet wheels for hand-winding.+The result was Cal. 1466 and the related family of movements.
