1655 mk1 - need help with errors

[sprocketty]

Hey gurus, question on this 3.0m serial 1655.

Does this look legit?

My concerns:
- 3.0m serial so one of the earlier 1655s
- MK1 dial, but that would mean a straight second hand is needed (watch currently has the later version second hands), or were there MK1s with non straight hands as well?
- Hands in general look "newer", possibly replaced?


Other than that, is there anything else visibly wrong?

Appreciate any thoughts!

Thank you :)
