Since coming into production in 1982, the ETA caliber 2824-2 has been one of the most well-known movements in the watch industry.

But what exactly is it?

The movement is considered to be a workhorse with a 38-hour power reserve. The movement is in watch brands big and small. Because of its power, it’s at least partly responsible for the incredible growth of microbands in the last few years.

ETA is a subsidiary of Swatch Group. The 2824-2 is an automatic 25-jewel movement and is found in watches of all kinds — from affordable ones to higher end models.
