When we wear the watch for a long time there will be some problems, so how do we do it to maintain.

Torsten has sent us this funky looking men’s or women’s watch. The movement is from the first generation of mass produced ESA/ETA quartz movements. It runs, but drains the battery within hours.

The movement looks very nice for a quartz watch.

I remove the circuit board first so not to damage it.

I now focus on the dial side, as I do not want to damage the day and date wheels.

I remove the plate that holds the day disk and hour wheel in place.

The movement does not look that dirty, but at closer inspection there is some dirt lying around.

Here I have removed the plate that holds the date ring in place. I’m extra carful when handling the plastic parts as they are 40+ years old and I do not know how delicate they are!

I now remove the setting mechanism.

The date driving wheel is damaged and I will have to order a new one.

The cap jewel is very dirty and is definitely contributing to the massive power consumption.

Here I have removed the cap jewel and the top pivot of the rotor is completely gunked up.

Here you can see the rotor and coil setup next to each other.

Now time to remove the rest of the gear train.

The Train plate removed revealing the gear train.

The largest quartz rotor I have ever seen.

Everything has been cleaned and is ready to put back together. Note I have not run the plastic pats thought the cleaning machine, as I do not want to expose them to the cleaning chemicals, The same goes for the rotor that is magnetic and would collect any metallic fragment it gets in contact with.
