There are so many permutations of “Seamaster” on these early watches (including not al all), I can’t say if there are any rules to it.
I based my opinion on the font and location of “Swiss Made” at the bottom of the dial and the fact that the dial still has dirt in the crevasses.
More recent rediallers have gotten wise to placement of “Swiss Made”, but then the dial would have been clean and very white. Older rediallers didn’t care. We rarely see “Swiss Made” on older redials.
So I am digging in on original, but very damaged.
