To anyone in the watch industry—enthusiasts, collectors, resellers, or manufacturers—the term watch movement is nothing new. Among the many names in the field, ETA movements stand out for their accuracy, reliability, and long-term durability. Millions of watches worldwide rely on ETA calibers, and for good reason: ETA SA Manufacture Horlogère Suisse, a Swatch Group subsidiary, remains one of the largest and most influential movement manufacturers in Swiss watchmaking.
In this guide, we break down everything you need to know about ETA movements: what they are, how they work, the most popular calibers, their history, and why both brands and consumers continue to trust them.
The term ETA movement (also known as Calibre) refers to an internal component of a watch that provides power and assists in the accurate operation of the linked components. These linked components include watch hands, date, chronograph, and others.
ETA produces both mechanical and quartz calibers used in mid-range and luxury watches. They also supply movement kits that allow watchmakers to create customized variations.
In short, ETA is the result of the merging of different Swiss watch movement manufacturing companies, which in 1985 became ETA SA. During the quartz crisis period in the 1970s to 1980s, ETA put all its effort into stabilizing the Swiss watch industry. As a result, ETA is considered to be the world’s largest watch movement manufacturer.
Mechanical movements are, in fact, based on components such as motors, gears, springs, escapements, and regulators. In the current era, mechanical movements are known as symbols of heritage and personality, particularly in the luxury category.
Two types are available:
