Some sort of laboratory mixer, yes? I worked with dozens of fhose ober the yesrs, and ah e a few rescued from disposal, but I don’t auite know that one.

How fast does the motor go, or better said, how fast does the shaft spin. There’s a huge range between various kinds of mixers like thst. Unfortunately the two I have are kind of slow — a few hundred rpm. Several thousand rpm potential is good.

Those sell for RIDICULOUS money on eBay if they are all there. Check out completed auctions OP. You will be shocked.

If you put your watch in there for cleaning you'd probably never have to wind it again either.
After a watch is disassembled, all the little parts go into a wire mesh basket that fastens to the bottom of that shaft. It gets dipped in a special solvent, and then in a rinse afterwards. More modern version have it all automated, so the machine automatically moves the parts from the solvent to the rinse.

(for no special reason I started watching watch repair videos recently, there are a couple guys out there who specialize in vintage watches that are pretty fun to watch.)

In my internship at a factory making devices for the military, I helped rebuild and improve a mixer that ran on an air motor, so it wouldn't have any chance of making a spark.
