Certina Certina 414

The Certina 414 is a manual-winding, open-face movement featuring a Breguet hairspring and small seconds display. It operates as a stem wind and set movement with the seconds hand positioned on a sub-dial. The Breguet hairspring provides temperature stability and positional accuracy, a distinguishing characteristic for its era. Production has ceased, and the movement was commonly used in watches from around 1930.
