Minor imperfections on Zaratsu polishing 44GS case.

[IS2000]

I have had a few Grand Seikos and recently just bought one with a 44GS case. I have noticed the high polished areas on this watch (flat like surfaces) do have visible micro scratches under certain lighting. The scratches are uniform, so it was probably marks from the polishing machine. My question is, is this normal for this type of specific watch cases? My 62GS and Omiwatari style cases are polished to mirror like finishes but those cases do not have many flat areas compare to the 44GS.
