The RR1103 is an automatic chronograph movement manufactured by BALL Watch Company. It is based on the ETA 7750 and was introduced in 2017 as part of the Railroad family. Ball modifies the base movement to meet COSC chronometer certification standards. The movement remains in production and powers several of the brand's railroad-inspired chronograph models.
