Ways to identify service parts

Fairly new to understanding all things Omega. I was wondering if Omega places any type of indicator on a replacement part? The reason I ask is that I had a dial replaced under warranty on my 2018 Speedmaster and it looks identical (to me) to the original, minus the flaw that caused the replacement.

I am no expert on this subject. Mainly replying to give your thread a bump, as it’s a good question.

If I’m not mistaken, with vintage Omegas, service rotors sometimes had a circle mark on them. And one can often discern service dials and hands, of course, via the type of lume present (or absent) or via subtle clues in wording or font. But as far as an actual indicator mark—on a modern reference—I don’t think so…
