Interesting Omega Dial: Can You Guess the Reference and Printing Technique?

Hello, Omega Forum Members,

Before I review another newly acquired watch, I would like to share a close-up picture of my watch with you.

Please note the rough texture of the surface.



I would like to pose a question to the community: How did Omega print the text on this type of surface?
Additionally, can you guess the reference number of my watch?

I appreciate your insights and look forward to your thoughts.

Best regards,
Teerapat

Thank you for your opinion.

However, those who are true enthusiasts may already know the answer regarding the reference. 😂
