Wth do I do with this IWC movement I bought at a little vintage store?

I didn't spend much on it. I'd like to turn it into a watch, but sourcing a
Cal 89 case is neither easy nor inexpensive as far as I can tell so far. Any
suggestions? -- Lisa

Hi Lisa

You need hour and seconds hands as well as a case.

Once hands are sourced, instead of making a wristwatch, why not have a mount
made, and use it as a desk watch, perhaps under a glass dome.

Also

There are talented casemakers out there, consider making it into a pendant
watch to be worn around the neck on a chain.
