I could use some education. I see the Seiko part number for the 6309-7040/-7049 bezel is 86019671. Thanks to Guy I have a near-NOS one coming my way.
I see that the 86019671 bezel also is OEM for the 7548-700X 150m quartz divers which is a slim case.
However the slim case 6309-7290 bezel shows to be part number 86019674.
So what am I missing? The 6309-704X bezel is the same as the 7548-700X quartz diver bezel, so how does the 6309-7290 bezel fit into this picture?
Any education will be greatly appreciated !

Part numbers for black and pepsi bezel rings maybe? Jumbled up over the decades?
I have my original 6309 and my brother has his 7548 both purchased new. I put new o rings in both the same day. Same o rings. Didn't notice any differences in bezel ring. His is a Pepsi, mine is black.
I put a Crystal Times coin edge on my Ramon special 6309-729A. It fits fine.

I had a nice bezel on a 6309 729(0?) a couple of years ago. The radial cut on the knurling wasn't as deep as it was on an early 7040 I compared it to, the lume pip was greener and the slope on the insert appeared fractionally shallower than on the 7040 bezel. It was still sloped, but didn't catch the light in quite the same way as the 7040. I wondered whether the bezel manufacturing differed on the much later watch ('85 IIRC) or whether it was a latter Seiko production run of replacement parts as have been rumoured.

I believe the differences are lume pip colour, slightly greener on the 7290. The insert is also I think a more glossy black, less metallic (slightly) than the 704X. The other differences I'm not 100% on but is apparent in the pictures I've posted, is that the knurling is slighty different, but only a tiny change in finish, but the border of the ring and the insert on the top edge seems very slightly thicker on the 7290. This thickness could suggest a different sized insert as it would be manufactured with the different finish and lume pip colour, but also a slightly different thickness of rim of the ring itself.
Interesting differences. My 7548s match the 6309 ring exactly, but again these subtleties show up compared to the 6309-7290.

NOS rotating ring for the 6309-7040/6306-7001 etc (8601 9671) And my 6309-7290 RR lifted from my lovely original. ( The things I do for you, Jon, although it gave me a chance to change the gasket and lube it which was worth doing ) Can you tell the differences? There is one, maybe two I can see. Guy THANK YOU for such an in=depth comparison. Yes, the things you do for me..... I REALLY appreciate it Sir ! Ok so the shape of the silver "V" at the lume pip is a biggie that even a dude like me can see. The other differences are very much subtle, although I too can grasp the sligthly wider top flange between the OD of the insert and the OD of the bezel top surface. So, they do indeed interchange, the differences are real and observable but on the other hand kind of minimal for a guy like me who at times can be OK with something that is not completely 100% perfect. I have learned a LOT here. Thanks again. Can't wait for the new 86019671 to arrive - and then I have to decide between the 6309-7049 and the 7548-7000 as to which old one to keep, which watch gets the better of the 2 old ones, and which watch gets the new NOS you have provided. So much to ponder !

Pleasure Jon. Learnt a lot too as I'd never really made a full comparison, just assumed it was lume pip colour. Whether or not later 6309-7290s differ from earlier slim versions (coinciding with maybe the 7548 and 7040s etc) or not, I'm not sure. I am not with my slim case 6309 at the moment but I think it's '85.
I miss having a cushion case 6309 or 6306 a lot.

Awesome stuff you got there Bodo. I can't really see the differences between those two but the pip of the other looks a bit small. But then again it isn't really a huge significant thing to be concern about. If I swap them no one would ever tell the difference.

(pip same size, triangle slightly different and lume colour notably always has been different on a 6309-7920)

Perhaps you're no longer human or rather you're a beast like magnificent Clint Barton.

Hah maybe you have a point, Sel. Really though the lume pip colour is always slightly greener, as for the other differences, yup it'd be hard to tell.

Bit late to the party here, but I think that you have all missed the real difference ...... On the 7040 bezel, and the early 7548 ones, the land that the insert sits on is much narrower (giving a bigger internal diameter) and to compensate for this Seiko added a stainless shim to increase the size to support the aluminium bezel insert. When they produced the 7290 bezel they just incorporated the shim into the body of the bezel, so one piece instead of two.......

Which bezels have an incorporated shim? You mean one that isn't removable and is part of the rotating ring itself, like an SKX for instance or am I missing what you are saying? The ones I've pictured above are a NOS 6306/6309/7548 bezel (same part number) and a 7290 bezel removed from an 87 example.

(The things I do for you, Jon, although it gave me a chance to change the gasket and lube it which was worth doing ) Can you tell the differences? There is one, maybe two I can see. Saw this thread pop up and had a read through it with interest. Great comparison. I have been interested in the texture of the bezel insert over the 6306/9 and 7548 diver range. I have a 6306 from 1978 with an insert which has a grainy almost dimpled texture which I have taken to be the correct insert for the 6306/6309 series of divers. Then I have a 7548 from 1980 which also has the same texture but a bit finer in appearance. My third watch is a 7548 from 1984 and has an even finer texture to the insert which is not as smooth or glossy as I have seen on say the 7002 diver inserts. I was wondering if anyone else has a late 6309 or 7548 diver from say 1984-85 and can compare it to an earlier insert from say 1976 -1980 to see if they have the same variation in texture to the insert. I'm assuming over the years of manufacture and from batch to batch there were variations to the bezel insert texture. I've tried to capture the difference in the following picture.
