It’s kinda wild right?
I put my name down for one when they were in production. This was at my then local AD where I had bought my first real watches (and first Rolex).
I visited him a few years ago when they had lost their Rolex account (after decades) and reminded him that I was still on the list. We had a good laugh!!!
Everyone knew that the 16520 would be in demand once Rolex moved away from this calibre.
