Need Help , Vintage Omega Ploprof 166.077 Real or Fake ?

Hi , i just recently purchase this watch for my Ploprof project.
before i start purchasing the parts , i would like to double check this watch authenticity first 🥲.
can someone please id the dial & insert ?
also does Omega release one with squared hour hand like this ?
is this Ploprof real ?
i have not had the chance to find a watchmaker to open the movement yet, so any information would be a big big help to determine this Ploprof.

Thank you !

Hello,
The watch looks ok to me. The dial may be an early tritium replacement given the oval shape of the zeros. The crown may be found on ebay so would not represent a showstopper for me.

Hello, Thank you for the insights.
Yes, i saw a couple listings for the crown sets on ebay.
guess i'm gonna pull the trigger now.😁

Edit: Duuuuh. I didn't key in on the one posted ahead of mine. Just call me the master of the obvious 😉

Looks original. Square hands were made, and the dial appears original. Service dials have the 3 o'clock marker touching the date window.
