Seamaster 600...Radial dial, no lum...raised numerals !?

This watch is bought...and in my possession...
There was a thread on this type of Seamaster 600 in Jan 2018.
The dial is very simple, no lum, raised numerals, not applied..
The dial is, what I have seen referred to as 'Radial'
Although, in engineering terms, it's referred to as a gramaphone finish...
I saw this watch in June of this year and assumed that it was a re dial, and avoided it...curiosity got the better of me today, when I saw it again...
I inspected it closely...I'm fairly happy the dial is 100% Omega and in almost perfect condition...text is crisp, with serifs...the case is clean and unpolished and the crown is correct.
This is a very basic watch...and what wasn't covered in the last post, regarding this type, was it's similarity to the 'Railway' issue watches such as the Universal or Perseo watches made for the Italian Railway workers...marked on the case back with 'FS'
So, did Omega produce a watch for this service...?
Please excuse any spellung mistakes...just had several vinos...Italy is HOT tonight. !!

There was a post in jan 2018 about this watch dial...
I will attach a photo of my, now sold, universal Italian railway watch....the basic dial layout, painted non lum hands and raised numerals, is almost identical in specification...the Radial or gramaphone dial is a very efficient anti reflective surface...

Nice piece...
I'm sure the Turkish railway authorities provided Omega watches...these were standard 'off the shelf' pieces I believe with the logo printed on the dial...
I just wondered if Omega identified a market for a dedicated railway or general service time piece...

Of course, the white faced Railmaster...I had forgotten...
I also had heard the use of 'Radial' in reference to the numeral layout.
In the case of my watch, I think the engineering term, 'gramaphone finish' is more appropriate as the surface of the dial is ridged, radially, like a record...
The term is used for the mating surfaces of industrial flanges / valves, for example. It prevents slippage of gaskets.
Omega, I know, designed and produced many, many dial variations for each model...this one is particularly interesting.
