167.005 crown help

Hello, could someone please tell me how you determine which crown is correct for a reference? Specifically I’m looking at a 1962 dog leg non pie-pan Constellation and it has a knurled crown. A lot of examples I have found searching on the internet have similar but I believe the correct crown is the decagon sided.
Coincidentally there is a similar watch in private sales and the seller mentions a member has told them the knurled crown may not be original. Seemed wrong to ask my question on their sale thread!

Thin decagonal crown, 4204 is the part number.

Here’s a related post: https://omegaforums.net/threads/constellation-question-about-crown.98234/

Thank you!

Thanks for getting back to me. A non original crown would bother me, I am way too uptight 😀

I’ve already been offered the correct crown by another member so all good.

I could find lots of examples of the ref on the internet with the knurled crown. I found 2 examples on the forum in private sales, one from 2020 that didn’t have any details on the crown and the current one already mentioned. One thread with a redial but the correct crown and a youtube video from “watch enthusiast” I think showing off the ref that said it came with the 10 side crown.

I was asking without loads of hope in case both types were used! If I buy it I’ll post pics …
