Thinking of making that pic my screensaver...
It’s a very well taken picture.

To the OP, I looked into them but decided it added way too much thickness for my taste.

I haven't seen those before, but they are definitely a better price than the Thomas Priek ones out of Germany:

A while back they would post them on ebay too though every so often, at a $.99 starting price. If you were patient you could pick one up for $60 or so, which is what I did. They appear to be thinner than the ones linked above, but I honestly don't know.

I have had a Thomas Preik for my Speedy for over 5 years now and it is perfect in every way. Really top quality

I’ve used the Thomas Priek case backs on a number of my Speedmasters and my Yachtmaster. All passed pressure testing.

I can take some thickness measurements of the different case backs I have installed on my Speedmasters

I have a Thomas Priek on a 2998.5, no problems at all.
You get what you pay for.

Measuring the thickness of the watches was not as straight forward as I thought, most of my Speedmasters have slightly different thicknesses of crystal even though they are all genuine Omega crystals. So I tried to measure just the thickness of the case back as best I could.

Standard 1967 steel caseback = 3.2mm
Original Omega Sapphire case back = 3.1mm
CCedar / Spiralwinderwatchparts = 3.4mm
Thomas Preik Sapphire case back = 3.7mm

Liking the idea of a sapphire caseback for my FOiS - might enquire about UK shipping.

Someone hinted to it in the link above but I couldn't see a definitive answer - Is there a reason the FOiS has a Rhodium finish movement as opposed to that of the standard Moonwatch? In my opinion it makes the FOiS 1861 better looking but seems pointless if it has a solid caseback. Am I correct in thinking its just and upgrade in manufacturing materials over time?

I'm considering getting one of these. Does anyone have one and can comment of the quality?

Thanks
Hi!
A picture is worth a thousand words. About quality, I see it correct, it fulfills its function and I do not appreciate bad machining. Everything fits quite well and easy to assemble.
I bought one and seeing how it was I bought a second one for my 105012 and it also looks great.

So it looks like they have come out with a new and thinner version of this display caseback available on pre-order discount. They are claiming it’s only 2.3mm in height! I believe the standard moonwatch caseback is over 3mm.

If my calculations are correct this would decrease the thickness of a standard 1861 moonwatch to pretty much the same thickness as the new 3861.

So you get a thinner watch with a view of the moment and hopefully more comfortable (the hippocampus does dig in a bit for me). Very intriguing… and I’m not affiliated with the company in anyway 😀

Finally got around to buy and mount one of the Preik ones. Top quality, but annoying the opener grooves is not made as on the original caseback = I had to do a special tool. Anyway - cool thing 😀

I think I already know the answer, but I just want to make sure.
If and when a Preik caseback is available for the new 3861 Speedmasters will installing one void the Omega warranty?

Thanks for the adress www.spiralwinderwatchparts.com 👍👍
I think I will order this one:

For a 105.012-66 (even if the double bevel disturbs me a little bit since it is not correct for a -66... !... 😲)

Thanks for sharing. I pulled the trigger on one for my 3570.50.
Will report back on the fit and finish (hopefully with some pics)
