Reminiscent of Seamasters from earlier generations . . .
. . . particularly bumper reference 2627 with date aperture at 6 o'clock.
Never owned one, but my cousin Vic has a ref 2849 . . .

. . . powered by Omega's first full-rotor movement with date aperture at 3 o'clock. Similar dagger markers to yours; a bit smaller, though, at 35 mm diameter vs 39 for the City Edition.
Best,
