ISA 1198 in 2824 case

[Rattlerviper]

So I'm putting together parts for my second watch build. I've got a 2824 case in the mail. It would make sense for this one to be quartz because it won't see much wrist time.

So if I purchase a ISA 1198 what problems am I looking at? I know the second hand is a different size. Will the crown fit? Is there any issue I'll run into if I decide to go this way?

isn't the stemheight totally different? Do you have only the case of also the dail?

I've got everything but the movement. I'm not sure if stem height is different. I've found several accounts if people using the ISA to replace the 2824, but no real info on how.

You can check the stem heights on Ranfft. I've heard of people sub the 2836 with an 1198.

Awesome website. I've just got to figure out how to navigate it. I appreciate you telling me about the website. It seems to be a treasure trove of info.

The figure you are interested in is "T" which is the stem height. Looks like 1.8mm for the 2824. You'd generally want to get this figure to be a fairly close match for the replacement.

 

Thw 1198 may come in differnt versions of stem height depending on if it has a date complication, etc. Check the datasheets.

Thanks Rodabod! My ability to access what I need just jumped exponentially. Im going to download the complete website on to my laptop later so if the website goes down I'll have a backup to use.

Try an 1198/101......

So in the end it looks like the 1198-103 works. I'll give it a go and if it doesn't work I'll have a movement for a new project.

Or I could just pick up a new dial without a date and get a new case for the dial I have. Choices[emoji23]

I think the 103 may be thicker than the 101.

[Rattlerviper]

Im sure the 103 is thicker because of the date complication. I'll check height vs 2824.

1198-103 is 3.7mm high while the 2824 is 4.6 mm high. Does that mean I would need to create a spacer for the back of the movement?

It depends on how the movement is mounted in the particular case.

Got ya. I wasn't thinking about how it would mount. Makes sense now that I actually think about it.
