Hi Folks,
I recently purchased a brand new orange Seiko Sumo. At first look I have to say it is definitely the most beautiful watch I have owned so far. The only fault I did notice was the chapter ring seemed to be a little off. Since I have done allot of research on this watch, I wasn't surprised, as I know some others have experienced this as well. As I didn't find it too noticeable I decided to just leave it be. I had bought a domed sapphire crystal for the watch and had it installed by my watchmaker. After the transplant it became quite evident (due to the increased magnification from the new crystal) that it is not the chapter ring that is off but the dial is misaligned in the case by about 1mm clockwise. I have had about a dozen people look at it as well as my watchmaker and everyone agrees. Althought at first it looks like the chapter ring in off, closer examination does reveal that both the chapter ring and bezel indexes are perfectly lined up with the case and that it is indeed the dial that does not line up properly with everything else. It makes me wonder if some of these other threads I have read about are really all chapter ring alignment problems or could others have misaligned dials aswell ?

The misalignment is in your chapter ring...not the dial...if the dial was misaligned your date would not be centered in the dial window.


The long and short of the common chapter ring alignment problems goes like this...



there is a centering post on the ring at the 12 o'clock position. The case is notched to accept the post, but I've noticed in several that I've worked on that chapter ring centering post has about .5mm of play which will allow the chapter ring to shift in circumstances such as when a movement has been removed for a crystal instal.

Next time you have the movement out for service or regulation you can make an adjustment to center the chapter ring.

Pictures can be deceiving, depending on angle. If you were to look at my watch in person you would see that if I turn the chapter ring clockwise to match the dial then both would be off to the right. As far as the chapter ring post , my watch was off before the crystal change, it is just more noticeable now due to magnification of the new crystal. I did remove the movement though and tried to turn it slightly when putting it back in. Doesn't seem as off now...so maybe there is a little play

The chapter ring is not the problem. The dial is definitely misaligned. The 12 o'clock position is fine but the 6 o'clock position is slightly shifted to the left. The shift is evident when you look at all the markers below the 3 o'clock level.
Since the dial is held in the movement by the plastic movement spacer, it is either a matter of the dial feet being out of place or the movement spacer having the foot mounting hole out of place. My money would be on the dial foot being slightly in the wrong place.


If I had that watch and it wasn't under warranty; I would remove the offending dial foot and align the dial properly.

That is what I thought and my watchmaker agreed, that the dial feet were off a little. Are you saying you would remove just one of the feet or relocate both feet? Because cutting off both feet off and relocating them would be quite a feet (seeing that we are talking 1mm or less).

Can the chapter ring be moved on this watch if it has a centering post as said in earlier post? If all I have to do is turn it, I don't mind trying it, if not just to ruling out chapter ring being the problem.

The misalignment on your watch isn't from the chapter ring or it would be out all the way around the dial; not just the lower part.
I don't know if there is a locating notch on the chapter ring or not; you can check that simply by taking the movement out and seeing if there is a tab on the dial. If there is a tab/notch then you won't be able to rotate it without surgery.


From what I see in your picture, only the lower dial foot appears to be out of position since the upper portion of the dial is pretty well aligned.

You need to look closer at his picture. There is is misalignment at the 12, 1 and 9. His chapter ring is off. It would take 5 min to fix.

I have looked closely and it is readily apparent that the dial is out of alignment; not the chapter ring.


If the chapter ring was to be rotated enough to fix the 6 o'clock position then the others would be out of alignment. As it sits right now; the 3 o'clock is nicely lined up.


If the dial bottom is moved to the right enough to fix that location, it will push the lower half of the dial toward the 3 and it will also move the 9 o'clock marker down proportionately. This is all because the upper dial foot is roughly between the 1 and 2 o'clock positions. That means the biggest movement will be at the 6 folloed by the 9 then the 12, with the 3 being the least affected.
It's simple mechanics :)

It's the chapter ring, and my black Sumo has exactly the same problem. Came like that from the factory. It's off to the same degree as yours, but it has never bothered me much. I plan on having the alignment corrected when it is due for its first service.

Had the same issue on a new samurai few years back sent back under warranty they changed the chapter ring made no dam difference as it was a dial problem it was pretty obvious to me, mine was not constant a few of the hour markers were out on the dial

Here is before pic of the Samurai

This is after a new chapter ring

as I mentioned it made no difference as you can see the markers are out of alignment from the 1 to 6 rest are ok, chapter ring alignment is an easy fix which obviously your watch maker would have spotted and made good, this is a different issue, as you have changed the crystal I assume warranty is void, with what this model cost these days it's a real shame, bought my Sumo when they first came out mine has the slight misalignment date window that was an issue in the early day.

You are right about only the top lining up. It is 4,5,6,7,8 that are not lining up. Plus, even if I did turn the chapter ring, then bezel insert would have to be taken out and turned aswell , as it "is" lined up with the chapter ring. I think that most watch companies, even reputable ones make mistakes. I have bought enough watches in my lifetime to see this. Therefore I don't disagree that some Sumo's have chapter ring alignment issues but it is also possible that some have dial issues aswell. If anyone can tell me that they had the same issue with top indices lining up but lower ones not, and that turning the chatper made them all line up then that would defy the laws of physics as I know them...

You wanna see some serious dial/chapter ring misalignment on a new watch? Check closely the new rubber tunas L.E. ... ;)






Dial, chapter ring, and bezel line up perfectly on this one ;D

I'm a perfectionist that hates chapter ring misalignment, and have seen it on several of my cheap Seiko divers. Most of the chapter rings have enough play that they can be rotated a little bit to fix the problem. But after looking at your pictures, latman, I believe you have a dial problem. I'd be pretty pissed, considering the price Sumos are selling for these days.


Thanks for pointing this out. I'll be sure to check closely on future purchases, to make sure any misalignment is simple chapter ring slop, and not a dial issue-

Hows it going Mark, I don't think it is Haters of the rubber protected divers, Just a matter of taste, That's all. The picture tou posted looks like the markers are off at 4,5,6,7 and 12, Probably the crystal and angle of the photo......

I think some of the posters here are a "little off", but prolly just the lack of emotion conveyed by text communications :great:

Don't think I'm 'off' in anything, Mark, but since I know this was aimed at me, I wasn't even referring to your particular exemplars of the rubber tuna, but rather some stock photos I've seen of that model. Please, don't be a fanboy.

BTW, I have a small collection of Citizen's ECOZILLAS, a watch known for having a 'luck of the draw' case of misaligned chapter ring to dial ratio. I have 7 of them, mixed amongst SS on rubber, Ti and SS on stock bracelet. Exactly 4 of them have perfect aligned chapters/dials....but 3 are off. I don't care about this problem even the slightest. Love the watches to death.

To me, it seems that you are the one being emotional here in the forum. ;)
