·Has anyone bought from Spiralwinder lately? I have been trying to contact them a couple of times through their contact form, but so far, I haven't received any response.

·I purchased from Spiralwinder in mid-November, the sapphire case back SKU: A1-CB3-2021. On the website, it lists this as fitting the CK2998 (which is what I have). The package arrived about 10 days later.
I can confirm that it DOES NOT fit the CK2998. When I stack the two casebacks together (OEM on top and Spiralwinder on bottom), with the case threads facing each other, I can clearly see that the diameter of the Spiralwinder caseback threads is ~1mm larger than the OEM. The threads will not engage at all.
Perhaps they accidentally sent me the wrong item. I've emailed twice and also used the website contact form twice, but no replies thus far.
Until they get this sorted out (or at least sort out their customer service) I'm reluctant to order from them again.

·Hi there Lewj,
did you end up getting this issue sorted? Keen to understand if the spiralwinder can fit the ck2998 or hodinkee h10 version.
I tried emailing spiralwinder but didn’t get a response
thank you

·Not yet unfortunately.
I finally received this email reply on Dec 10th:
"Thank you for your order, and for getting in contact with us. It appears that Omega used a different caseback thread for later batches of ck2998 watches. This may be the unique thread used on the Trilogy edition, or Omega may have been testing the threading later used on the 3861 models. As a result, this caseback won't fit, so we can coordinate a return and refund for you. If you'd still like to add an exhibition caseback to your 2998, please let us know if the thread diameter of the original caseback, and let us know if there's a dust cover or o-ring on your movement holder. We can check to see if the 3861 caseback may fit. In any case, let us know when you've sent the return caseback so we can track it and get you your refund! Best, Warren"
I replied the next day with calliper measurements of the OEM caseback and the answers to his questions.
I originally had to pay for shipping (as well as Canadian customs), so I requested a pre-paid return label (since the error was his).
Since then, I've re-sent the email one more time.
18 days later, still no reply.
As far as customer service goes, I've certainly experienced worse. But this... isn't great.

·hey Lewj,
Thanks for getting back to me with the detailed response.
Hopefully Warren will reply back soon. Agree not great communication though, a lot of these smaller outfits run these things as a one man side business, which is fine when things run on auto pilot, but such a frustration when things don’t go to plan. Good on you for being calm and patient.
It would be so good to have this fit the CK and the H10, I also find the original omega case backs very uncomfortable and digging in, so if this can be rectified and lose 1mm in height it would elevate the wearing experience so much.
Do you have the blue or black CK2998 ?

·Forgive my ignorance but does the FOIS and CK2998 have different cases? They look identical...

Ah interesting. I have the 2016 blue model, but the Hodinkee anniversary released 2018.
I will ask my watch maker to crack the cases and see if there is a difference in the threads or not. So weird Omega decided to change the threads despite the rest of the case being identical to FOIS.
It’s just a shame that Warren from spiral winder is not that responsive, as I have emailed him about 2 weeks ago with questions, but still no reply.

·Update on the Spiral Winder caseback situation for my CK 2998 Pulsometer bezel.
I looked like there is no suitable caseback for my watch, available through Spiral Winder. Warren has reached out to me and issued a full refund.
Since I am in Canada, shipping the item back would have been too costly, and he has relinquished the item for me to keep.
If anyone located in Canada can make use of this, let me know and we can work something out (to cover the cost of shipping and customs that I've already paid).

·I got an update that spiralwinder casebacks are now in stock and noticed they have an engraved option. I’d love to get an OEM exhibition back, but as those are quite pricey and harder to find, I was happy to try out spiral’s option. It just arrived and it’s quite nice. No idea how well the enamel will hold up, but for the price and quality, this definitely scratches the OEM itch. 👍

Any idea how much it adds to the thiccness of the watch when coming over from a solid caseback?

However, to more answer your question, @blueteg did provide measurements. Granted this is a standard speedy and not the 3861, though I imagine the results will be similar.

Dude, that looks awesome!! I saw one of these on another forum a couple weeks ago and was wondering who else was making aftermarket sapphire casebacks w/ the script. Now I know! 😀

·Order the v3 caseback wanting to fit on the CK2998 Blue, but it doesn't fit. I read the notes on the website saying it doesn't fit the Black Pulsometer CK2998 and later versions and assumed the older 2016 Blue CK2998 would fit. Have emailed them, will see how it goes.

·Hopefully quick question for those familiar. I gather the Spiralwinder case back doesn't need a separate spacer ring (equivalent to the iron dust cover in the OEM setup) because it uses a 2nd 'gasket' (not the main caseback gasket that is used for water resistence, but a smaller diameter one).
I gather from reading this thread that the inner gasket part is somehow sandwiched between the movement plate and the caseback, kept in place by friction and preventing the movement from shaking around in the case. However looking back over this thread and on the Spiralwinder website I haven't seen any photos of it. Is it a hard plastic ring or flexible rubber more akin to a regular gasket? I'm wondering if the ring/gasket is a part that needs lubricating with silicon grease, if it is likely to wear out over time, replaced as a consumable part at every service interval, etc.

·Its a normal looking rubber o-ring, same as the case back gasket but smaller. I didnt use any lubrication on mine (if i remember correctly) and I doubt it would ever need replacing, assuming that the gasket doesnt get damaged.

Thanks, good to know. Should the inner o ring sit in a channel within the case back to keep it in a round shape? Or it's just loosely laid in there and you hope for the best when screwing the caseback down? The reason I ask is I noticed the attached photo from another forum member (@mutanthands) where the gasket doesn't appear to have made proper contact. However, it might just be my eyes and what I think I'm seeing in the photo (circled red) isn't actually the gasket.
