i almost exclusively buy used. im a cheap bastard and love the savings. all of these are VERY different and will wear very different. ya really need to try them all on and get whats most comfortable. or as the old saying goes...buy all 4. not sure if srs. rolex holds value better than almost any watch ive owned. actually, i get a ton of comments on my watches. my panerai 232 almost always got a comment every time i wore it. however, i almost never get a comment on any of the rolexes ive owned.
