Rado movement replacement

[RadoHelp]

Hi,

I have an old Rado Diastar Quartz watch that belonged to my grandpa, but it doesn't work anymore. My dad tried having it repaired once and had a terrible experience with Rado. In the end they flat out said they couldn't repair it and gave it back.  The design of the watch seems common to a number of old Rado watches, both automatic and quartz. I can't seem to find a second hand quartz movement but found automatic movements for the same design. Would it be possible to replace the quartz movement with and automatic? I'll add some pictures of my quartz movement and the automatic(ETA2789).

Thanks in advance for any advice!

The case may look the same, but I doubt an automatic movement would fit into a case made for a quartz--it wouldn't be deep enough to accommodate the thickness of the movement. The ETA 2789 is 5.9mm in height. Can you remove the quartz to measure? While you're at it, it would be worth looking closely for any markings or identifiers for the quartz to see if another brand used the same.
