Speedmaster pre-moon 145.022-68 with -69 dial?

Hallo Forum - Speedy experts please help

Yesterday I got the Moonwatch Only book and started checking my pre-moon Speedmaster.

Here are the data of the watch:
- Movement nr. 27325xxx - Within 145.022-68 range
- Case ref 145022-68
- Calibre 861 "B1"
- Caseband "C1"
- ...........but dial C1 step with printed logo - For 145.022-69 to 74

Could it had left the factory like this or was the dial replaced.

For how long did Omega have service dials of the step type?

Looking forward to what the experts think.

SORRY FOR THE AWFUL PICTURES

If you want accurate information, provide good photos. https://omegaforums.net/threads/vintage-omega-posting-guide.383/

Edit:

I can’t tell in the photos. But it appears not to be a step dial from what i see, but a modern replacement. They don’t have service step dials, to my knowledge.
