Can't comment on that particular one--it looks great+correct, but values are all over the place. I will, however, note that in a dozen years of bringing watches to the best watchmaker I know, the Tudor cal 390 gave him the most trouble--not because it's a bad movement, but because parts are just impossible to find (the early subs ran on 390s, too, so most parts have ended up in those watches). If you can be certain that it's recently been servied by a qualified watchmaker, sure (depending on price). If not, I (personally) would pass.
