re: OT watch experts Omega Seamaster Diver 300

Check the classifieds of some of the bigger watch online communities and I would imagine you can find a nice used one in that watch and save a good bit, unless you are after the buy new experience. I am not sure if it is kosher to link for sale forums here, so I will just provide names - rolexforums.com has a non-Rolex buy/sell section that has a great number of high quality sellers as well as individual collectors that will post. The same goes for watchuseek.com and timezone.com. I've never bought from Reddit r/watchexchange, but I keep an eye on it and I see some good stuff float through there. I like having full sets (ie box and papers), but so many of this model are sold grey market that you might have a hard time finding one with papers. I would pay attention to service history as well if buying used.
