Welcome to the forum
I personally don’t believe in grail watches. IMHO, you buy each watch thinking it’s the last one, or the be all end all … and in the end, it just becomes another watch in your collection
Some watches are maybe more special than others, but something new always comes along.
In your situation, I’d keep the Rolex, (unless you just don’t wear it) and I’d keep saving for the 321
