Interesting. Omega's vintage database shows a picture of CK 2927 with a 244 movement, calls it "center sweep", but the pictured example has no seconds hand.
I'm guessing it's mostly right. Dial does not look obviously refinished.

Where in the database entry do you see the "center sweep"?
but the pictured example has no seconds hand.
"Central sweep‑second hand 17 jewels Created in 1950" when describing the caliber.
I think I see the second hand pinion but no hand. either it's simply missing the hand or it was removed because the gear train driving it is screwed up, which is a dirty trick NYC flea market hawkers do to screwed up watches.
Database is wrong. Caliber 244 does not have a seconds function.
