1960s Oyster Precision - Dial question

[flightlevel150]

Good morning,

A friend of mine just purchased this 1964-65 6424 Oyster Precision. Looks great IMO, and according to the pictures of the listing the Serial Number, movement, t Swiss t check out.

However I have a question about the font size of the word OYSTER below ROLEX. It looks like the font size is the same for both words, which I don’t think I’ve seen elsewhere.

I know that different manufacturers used to produce Rolex dials so he’s not overly worried, but what do you think? Have you come across a dial like that? What do you think of the other pictures?

Many thanks in advance for your precious help, I’m always amazed at the wealth of knowledge across this forum.
