So you're new to luxury watch and probably Rolex as well. Some tips:
1. Don't buy a luxury watch because it's presumed to be "collectible" or "rare".
2. Take your time to choose a watch you like, not what others say is the "best" model. Arguably, many will insist a first Rolex must be a Submariner Date or GMT Master II. I liked neither at first and got the Explorer II which nobody likes.
3. Don't believe that you cannot lose money buying a Rolex. The amount you lose is small or large depending on whether you bought it new or used. Even if you buy pre-owned from a dealer, expect to lose at least 10% if you decide to trade it in later, say within a year or two.
