Collector Notes & Dating The Eterna-Matic is one of the most significant milestones in 20th-century watchmaking, defining the standard for modern automatic movements. This specific 1959 model (movement serial 4443128) utilizes the revolutionary five ball-bearing system introduced by Eterna in 1948 to reduce friction in the rotor. This innovation was so successful that the five dots became the brand’s permanent logo.

It represents a period when Eterna was at the absolute forefront of Swiss mechanical engineering.
