A Rolex Submariner 6538 to be soon auctioned.
A superb dial, that's for sure. Credit picture: Phillips.

Now one question: The watch is from 1959, according to Phillips, which seems to correspond with the case number.
But isn't the 4 lines dial a bit later?
Looking forward to reading your opinion on that point.
Best,
Nicolas
