We need the reference number from inside of the case and maybe a picture of the movement.
BTW, I have never seen a poinçons de maître with a letter (not number) inside the hammer head mark.
Here's a similar case on a Tissot. It's the only other "2307 60" that comes up on Google, so perhaps both cases are not genuine.

Don`t say that generally on the hands there are Omega out there with dial and hands solid gold.
I don`t think so for this watch but just for information.
All parts of the movement are copper plated against korrosion something Omega does till today.
