Stern Sonneberg Consul - how to remove the clock?

[PJ.]

Hello,
I recently bought this nice radio and it's usual cleaning and checking. But how to remove the whole clock mechanism? It needs usual inspection, bu after removing back cover of the clock I see that there are screws, which are evidently screwed in the front of the radio (behind that golden panel). I also wonder, how to remove this small knobs - inner ones have a hole, but the outside ones don't...

Regards,
Piotr
