This Seamaster Purchases made through these links may earn this site a commission from the eBay Partner Networklooks good but not sure about the dial. The "S" in Seamaster doesn't look correct. People with more experience can chime in.
I think it's ok. I see what you mean about the S but although the rounded S is usually later it does appear on some early Seamasters. Here's an example that was sold on here: https://omegaforums.net/threads/seamaster-2767-waffle-dial.24076/
It's hard to see in the photo, but are there lume dots in the ends of the applied hour markers, or are they lame-free? [Edit: Printing looks good to me, by the way.]
I also think the "Seamaster" text is fine. There was a discussion in this thread and I'd say this is similar to mine with 13.8 million serial. Cheers, Chris
