Looks like a ck2998 but with the colours muted to look black instead of blue. Hands are different though. Maybe it’s this years ST, the Hodinkee version. Not very imaginative if that is the case.
Def not the blue ck1998. I had considered it was the sedna gold FOIS (Reference 311.63.40.30.02.001). Some pics online of the sedna gold model look like the gold does not come through and it can appear steel.
I believe that is it. On the first photo the gold is just not reflecting in a way that you can tell it's color. Same with the sub dial hands. I think they're just not reflecting anything.
