Questions, Answered

Everything worth knowing before you build.

What is a chapter ring on a watch?

The chapter ring is the ring that sits between the dial edge and the case, carrying the minute and hour markings around the dial. On SEIKO's SKX models it's a plastic part from the factory; ours is machined brass with printed markings for a crisper, more finished look. Swapping it is one of the simplest cosmetic upgrades in a Seiko mod — a small part with a big effect on how sharp the dial side reads.

Will this chapter ring fit my SKX007?

Yes — it's a direct replacement for the SKX007's original plastic chapter ring, sized as original. It also fits the SKX009, SKX011, SKX171, SKX173, SKX175, our 42mm Diver's watch case, and all 7S26-0020 watch cases.

Does the SKX007 chapter ring have an alignment pin?

Yes — like the original, it keeps the protruding pin at the base that locates the ring and holds the hour and minute markers in alignment with the dial. Fitting is as per the OEM part: seat the pin and the ring sits exactly where SEIKO intended.

High quality and great shipping!

The piece arrived within about a week and a half of ordering. The chapter ring is very well made and I am more than satisfied with the quality. I can't wait to put it into my watch! Just waiting on a few more parts...

Thanks for the review Kirk! Hope you get your other parts soon so you can start modding =) Anticipation must be building.

I have an unbranded 40mm diver watch case off of eBay that did not come with a chapter ring in it. Will this fit a 40mm diver watch case?

Adriel from LuciusAtelier.com

Hello Ryan!

Thanks for expressing interest in our mod parts.

No, it will not fit unless it has the exact dimensions of a SEIKO SKX007 or a 7S26-0020 SEIKO watch case.

Let me know if you have anymore questions.

Cheers,
Adriel
