Hello, I use an N296 in one of my 13322s but not all cases with this reference are the same. Do you have pictures, and I can tell you if it appears to be the same? I suggest you purchase a vernier calliper which could help you ascertain if this is the correct size too! Best wishes, Oliver

Thanks Oliver, I just found my callipers, it measures 29.3 inside the little lip where the crystal should sit. Should I size up slightly or order 29.3? Thanks for your help

they usually come in orders of 2, e.g 300/302/304/306 etc. If you have a crystal lift I would suggest buying a low dome 294 & 296 and trying them both to see which fits better. I use the sternkrauz N line.

Thanks, are you saying I need a 30.2 mm not a 29.6?

I would recommend just getting the ones I have recommended. They're generic so very cheap, and as Omega crystals didn't have the logo in the centre in the 1940s there is no need paying extra for an Omega crystal (which will likely also be more difficult to obtain).

That is the Omega part number. The 29.6 will be far too small...

Archer, with respect this case reference 13322 came in various sizes. I have 2 of these watches in my collection currently that both have ever so slightly different shaped cases and have measured both today with my callipers - and both use different sized crystals. One is a 296, the other is a 302. I have seen many 133322s so how can you be sure his one is 302, especially given the fact he has measured it with his vernier callipers at 294? It seems quite a push to compress it so much for a crystal lift to be able to insert it if it’s 0.8 bigger than the hole? Of course his measuring might be incorrect - but how can you be certain it is this bezel? Best wishes, Oliver

Thank you oliver, I have the two sizes you recommended on order so will try there first. As you say my measurements points towards your recommendations so will start there. Thank you both for taking the time to respond

I’m going by what Omega calls for on this case. If people want to follow that or not is completely up to them...

It would be highly unusual for Omega to use the same case number for two completely different sized cases.

Curious, are the cases by the same maker?

Yes both are by Dennison, the 13322 code is the Dennison reference number as far as I know - not an Omega case reference as we usually know it. One of mine is the same as a Swiss 2754 and the case measures 34.5mm and the other is similar but a little smaller (33.5mm) hence why the bezels are slightly different too and the crystal size. They all generally have the same approximate case shape but I have found these differences. I’m happy to proven wrong - but I am quite certain both of my examples that I currently own are original and I can’t see the 302 crystal fitting in the smaller cased 13322. Let’s see how the OP gets on with the generic crystals and then I suppose we’ll know. As they’re cheaper it’s less of an investment too (around £2-3 each). Best wishes, Oliver

I have no idea what you have in front of you - if it's a third party case, a mix of parts or whatever, but there is most certainly a 13322 case from Omega for the 30T2 movement...



In addition to the steel version, there is also one in 9k yellow gold. It only has one crystal for it - the one shown above. So if the watches you and the OP differ from this, well so be it, but they don't jive with what Omega calls a 13322 certainly.

The Dennison 13322 case doesn't come in 2 sizes as far as I am aware, and I have around 300 noted in my list, mostly Omega. It does come with different case backs for sub or centre seconds, the latter being deeper for obvious reasons. It is a 3 part case so a crystal lift is not the best way to fit a new crystal, in my opinion. The case comes in s/s, plated, 9k gold and silver, the latter I have only seen dated 1939. Many watch manufacturers used this case, primarily Omega, Longines and Smiths, but I have also seen Movado, Tissot, Olivant and Botsford and even an IWC. I have 3 Smiths and a Longines in this case and the crystal is 29.2mm for mine.

So again your one is different to both of mine and Archers. Proving disparity…

The two I currently own are a 9k gold one which indeed uses the crystal Archers recommends. The other is a steel one which uses a 296.

Both are Dennison - perhaps the disparity is found when comparing 9k 13322 cases with steel 13322 cases? Both of mine are subsecond 30mm calibres, the 30T2 (steel case) and 267 (9k gold case).

I have owned another steel one in the past and that used the same size crystal as my current steel one - 296.
