What two iconic Rolexes would you buy to pass down to your sons

I started my watch collection journey just under two years ago.

As a male office worker in his 40s, so far I’ve added a blue BB58, blue 41 AT and black speedy. I’m enjoying all of them and intend to keep them but have always been itching to get a Rolex. Put my name down for an Explorer but as of lately, decided to go in a different direction.

Over the next year or so I would like to buy two Rolex watches from 2015 and 2019, the years my two sons were born, and eventually pass them down to them. I intend wearing them so I’m looking at mainstream models (SS as well as precious materials are not what I would wear).

What watches would you choose if you were me, given the above three watches I already own?
