ETA 2472

Description

The ETA 2472 is an often used selfwindig movement with a date indication. When it was launched in the early sixties, it reflected the state-of-the-art with its decentrally located minute wheel and the two-way selfwindig mechanism. The rotor is axle-beared and drives the familiar ETA ratched wheels.

The large ring balance beats slowly with 18000 A/h and is of course secured by two Incabloc shock protection systems. A novelty was the moveable hairspring stud, which allowed, together with the long regulator arm, a precise and simple regulation.

The date advances instantly at midnight and can be corrected semi-fast.

This movement was also used by Kienzle under their number 70/1.
