It's not a probability.
It's a fact and has been the case for quite a long time.
It's understandable really, as i think i saw somewhere recently that Rolex make more watches than the other 3(maybe 4) other combined top manufacturers in the world in their own right and keep in mind that all Rolex movements are COSC tested prior to the in-house Superlative Chronometer series of tests.
Basically, it's entirely fair to say that nobody else can ever come close to the crown in that regard.

Of course there is METAS now, so the mix of accurate watch movement testing is rather different.
But the crown is so far out in front that it's not even a race.
It just is what it is and impressive.

Thanks for delving deeper into it
