is this 2518 original?

A atombob

looks very nice overall but have a few unusual places:
1. the space between official certified and sea master is too close and the font of official certified is strange.
2. the omega inside the triangle in the backcase looks strange.
3. I cannot find any 14k gold marks on the case. I used to see marks on the lugs from a few other YG2518.

Please share your thoughts. Very appreciated.

Case back has the 14K markings. Photos don’t show where markings could be on the backside of the lugs. Looks to have met a polishing wheel or two...

It's an original dial. My concern about this one - and I looked at the photos on eBay - is it looks like the dial was chemically cleaned.

And looks like there is a hallmark in the lower left lug.

The fonts look a bit faded in parts same with the luminous markers and the minute hash marks. A sharp high resolution photo of the dial straight on would be helpful.
