it really boils down to your budget. for example, if you are looking at sub 10k, then you are looking at a very limited range. pre-owned moonwatch gives you a very basic watch with lots of history and easily movable in the secondary market. somehow the sweet spot for preowned watch is around 10-20k. it will open you up for a wide range. Rolex Explorer II, Submariner, Panerai Base models, JLC reverso & etc
