ETA

ETA SA Manufacture Horlogère Suisse is a prominent Swiss watch movement manufacturer, headquartered in Grenchen, Switzerland. As a subsidiary of The Swatch Group Ltd., ETA designs and produces a wide array of quartz and mechanical watch movements, including both hand-wound and automatic calibers. The company's origins trace back to 1856, with roots extending to the 1793 founding of Fabriques d’Horlogerie de Fontainemelon (FHF). Through a series of mergers and acquisitions, ETA has become a central figure in the Swiss watch industry, supplying movements to numerous brands within and outside the Swatch Group.

Notable ETA Movements

ETA has developed several movements that are widely recognized for their reliability and precision:​

• ETA 2824-2: A robust automatic movement featuring 25 jewels and a frequency of 28,800 vibrations per hour (vph). It's available in four grades—Standard, Elaborated, Top, and Chronometer—each offering varying levels of accuracy and finishing. ​

• ETA 2892-A2: A thinner and more refined automatic movement with 21 jewels, operating at 28,800 vph. Its slim profile makes it suitable for higher-end watches and complications. ​

• Valjoux 7750: A widely used automatic chronograph movement known for its durability and ease of maintenance. It features a cam-driven chronograph mechanism and is favored by many watch brands for its reliability. ​

• Powermatic 80: An evolution of the 2824-2, this movement offers an extended power reserve of up to 80 hours. It's utilized by several Swatch Group brands, including Tissot and Certina. ​

Industry Influence

ETA's extensive production capabilities have positioned it as a dominant force in the watch movement industry. The company's decision to gradually reduce the supply of movements to external brands has prompted many watchmakers to develop in-house calibers or seek alternative suppliers. This shift has significantly influenced the landscape of Swiss watch manufacturing.
