Location of watchmaker’s initials regarding modern Ed White 321B?

Greetings from Cincinnati, Ohio USA…

I recently acquired a modern Ed White via the secondary market and have heard/read that the specific watchmaker who built this watch has initialed it. I was wondering if those initials are visible on the movement…I’ve checked and haven’t observed any initials present…but then again maybe I’m not looking in the correct location.

Also, if the initials are not visible, out of curiosity, where would they be located?

Thanks in advance, fellow OF people. Pic of my specific 321B movement below…

Can't answer that question, but it would surprise me if it's on the movement. This type of thing (if it exists) is typically inside the case back, like on this JLC I own:

Roger that, @Archer…thank you, sir. 👍

Fantasy initials below…some Omega watchmaker whose name is “Mad Dog”…how freaking cool would that be? 🤪

I've not heard that about the EW321, but I don't see what the purpose would be. Omega's records would show who assembled the watch, so no need to mark it anywhere. Scratch marking cases is not considered acceptable any longer, I think that would go double for marking a movement. I did hear that if a EW321 came back for service under warranty it went back to the original assembler for correction, part of the learning experience.
