how to get this nice and smooth shape like this

Thanks Michael
Please notice I would like to have a ring that on the side would look like that




I used yellow as a scaling rail.


But when I extrude the circle for finger hole this is what I get. So the side view changes dramatically from what I initially wanted.



So I cannot put two and two together.

Can you advice

Thanks
