3 Submariner Collection?

[NicoM]

I always thought my first Rolex was going to be a DateJust, but my tastes have changed and I'm now very much into the Submariner, specifically the Hulk and the full yellow gold with blue dial and bezel. I've finally gotten myself in a position where I'm comfortable shelling out money for the Hulk and the 116618 will remain a frail for now.

Here's the thing... I also know that my father will be passing down a two tone black dial Sub to me in a year or two. It's the most recent 116613 which he got when it first came out.

Right now, it looks like I'll be owning at least two, if not 3 Subs in the next 3-4 years. (The 116618 is a stretch, but I like to dream big). I personally find the idea of an all Sub collection to be quite interesting, but what do you guys think?

I know there are Submariner collectors, but they mainly focus on vintage model. Does anyone here "collect" modern day subs? Or stick to any one model line for that matter?
