I would guess the bezel insert and the hands have been replaced. The rest looks OK, the crown is hard to tell without removing it.
Just take a look at this: http://www.thewatchsite.com/15-vint...eiko-6309-diver-collector-s-buying-guide.htmlOkay, so I am new, but how do you tell aftermarket parts? I search and there are posts of "signs" but it is just a trained eye over the years?
Regarding the hands: on an original set of hands the "corners" of the minute hand are not quite as "sharp" as an aftermarket hand. Likewise, the texture of the lume on the hands is different - the texture of the lume is more pronounced and visible on original hands, and not quite as "smooth" as on AM hands.
Lots of times you can look at the printing of the numbers on the bezel insert and see the "smooth" vs the "textured" printing and ID the differences. Same goes for dials.
Punch in some SCWF searches like "6105 dial and hands" and let your fingers do the walking!
(*And I stand ready to be corrected on the above information...)
The bezel insert is slightly wrong in many ways - the black isn't matt enough, the font is slightly to thick, the outer edge doesn't fit into the bezel quite perfectly, there's no edge around the lume pip, and the whole thing just looks far too new, not over 30 years old. The hands are a bit trickier, the lume isn't quite the right color and but overall the quality isn't quite up to Seiko standards, the metal isn't flat enough and the edges aren't crisp enough to my eye.
Wow, that was extremely comprehensive. Thanks! Do most watches have that thorough of analysis to help new comers like me? You dont have to direct me, I am just wondering.Just take a look at this: http://www.thewatchsite.com/15-vint...eiko-6309-diver-collector-s-buying-guide.html
