This one is actually hard. If you really like the watch 2500 isn’t entirely unreasonable for one of these but it’s not a good deal either. It’s a smaller / midsized 36mm watch, so are you aware of and ok with that, and are you also specifically into a 1990s 18k gold Seamaster?
The movements are solid and it’ll be cheap to service but just be sure this is a watch you really want because if you buy it, it’s likely to be hard to move on if you change your mind later.
