Stripping an Eterna 1479K. Mostly ETA looking parts (not surprisingly), but the auto mechanism is different.

There's a part retaining one of the auto gears - I'm not sure how to remove it. It looks like it's pushed on.

Marks in the slot look like it's been twisted with a screwdriver.  

Any ideas ?

Hinges  around the pole its mounted on, push to turn.

Avoid taking it off the pivot.

Thought so, but better to check than break something !

It seems a bit crude when the rest of the movement is such nice quality - the click is beautiful !

If might be a screw, not just pole, either case you should avoid anything that may loose the retainer. 

I have seen some glued, which tells me must have got loose for whatever reason.

With a screwdriver in the slot, it turned smoothly. I wonder why they didn't use a screw?

Beats me.     Screw head if there is one,  would be on the other side, just like your ETA,  some variant do some don't have screw.

Looks almost identical to an ETA cal. 2472 that I serviced a year ago.

If interested you'll find detailed pictures from my service walkthrough here.
