What's wrong with this CK2077?

Hello!

Links to auctions have been posted here from time to time, so I hope there's nothing wrong about this one. I have no affiliations with the seller, buyer or the auction house.
Today in Monte Carlo (lovely place, isn't it?), Important Watches auction took place.
Among those important watches one Omega ref. CK 2077 (https://www.artcurial.com/en/lot-omega-ref-ck-2077-ndeg-9384870-9555478-m1068-21).
I can't find it right now, but I've checked at some point during live bidding, and realised price of 11k € was listed next to lot no. 21.
So the question is - as stated in the title - what's wrong with this watch? I'm total newbie, but it looks quite nice to me. I google this ref sometimes and, while 11k by no means is cheap IMVHO, this is the lowest price in last few years. There's always a reason for people paying more, there must be a reason for people not paying more. 😉

Pictures (from the listing):

Nice one. Original dial. Luck for the buyer? Why did you not buy that one? Kind regards. Achim

Staring at those pictures for a while, crown doesn't look right and pushers seem to sit low compared to others. But it might just be a picture.

Not my price range. 😁

Pushers are for sure original and the more desirable fat sized early version. Case is the more desirable double step version. Crown looks original too but I can't say for sure. Low price seems to be due to a less desirable dial type and maybe lack of exposure to the sale. All else equal, a black galvanic gilt dial would go for multiples of this one. But it is a very nice watch in its own right.
