ETA SA Manufacture Horlogère Suisse is a prestigious Swiss company specializing in the manufacture of watch movements (also known as "calibers"). Founded in 1856 and currently part of the Swatch Group, ETA is one of the most influential and recognized companies in the Swiss watchmaking industry. For decades, ETA has been the silent engine behind numerous watch brands. Brands such as Tissot, Hamilton, Longines, and many others within the Swatch Group use ETA movements. Many independent brands and micro-brands have also historically relied on ETA, although in recent years the company has reduced its external supply to focus on its own brands.
Their automatic movements, chronographs, and precision quartz calibers have been industry standards for decades.
