There are similar references without the internal rotating bezel . . .
. . . but those have distinctly separate - albeit similar - numbers. Ref 145.016 has a minute and 1/5th second hash marks at the perimeter of the dial. Ref 145.020 has an internal tachy bezel.
Your reference has an internal rotating bezel with either 5 minute or 'roulette' markings. It should be ok. You might have a service dial, but that's not really much of an issue.
