Yes, we've covered some of that already in this thread. e.g. post 127
So e.g. this:
"1926
The first waterproof wristwatch
In 1926, the creation by Rolex of the first waterproof and dustproof wristwatch marked a major step forward. Given the name “Oyster”, this watch featured a hermetically sealed case which provided optimal protection for the movement."
from Rolex's own website (here: https://www.rolex.com/about-rolex-wa...tory/1926-1945) accessed today.
And:
"Since the creation in 1926 of the Oyster case, the first waterproof case in the world, we have developed multiple innovations that have honed this hallmark." Again, Rolex's own copy (here: https://www.rolex.com/watchmaking/ma...waterproofness )
Really?

And the Rolex forum had their minds blown here:

("Wait, what, Rolex lied and are still lying?")
good discussion (to which Stan Czubernat contributes) here:
