ETA SA 2813

The caliber 2813 is a Chinese movement, sometimes listed as A2813 or DG2813, produced by multiple factories including Dixmont in Guangzhou, Mingzhu, and Nanning. Despite its name, it is not an ETA clone—there is no ETA 2813 to clone. It is closer in design to the Miyota 8215, though with notable differences. The movement remains in production.
