The ETA’s Autoquartz

For your information, I do not repair this type of watch.

The caliber ETA 204.111 is born in 2001. Diameter 25.60 mm, height 3.95 mm, 17 rubies, frequency 32,768 Hz.

Principle

The oscillating weight transfers its mechanical energy to the micro-generator through a micro-barrel. The generator converts this mechanical energy to electrical energy and stores it in an accumulator. The accumulator provides the power to the integrated circuit controlled by the quartz, which, hence, generates the signals to command the motor. Autonomy of 115 days. This movement accumulator can be recharged electrically on Cyclotest, on Chappuis or by the winding-shaft. One can pull the winding-shaft and after 8 minutes the watch stops. Hence it avoids discharging the accumulator.
