Hi Jenneke, thanks for that. I have 422-998 L731704 but a search hasnt found one.
Start your searches for the movement/case combo at gruen.watch.

One model is listed, luckily they have the marketing name: "Heritage." The marketing name will help find the crystal in the absence of measurements.

Now google "Gruen" "Heritage" crystal. This yields CMF309 and a listing at eBay.

Finally, take this crystal model to TipTopCrystals to search for alternates and additional marketing names.

Here we get even more interesting info:

Gruen: 422/998, Dunbar, Heritage, Hollywood


If it has a service history, price is not bad. Without a service history, I wouldn't pay more than about $25 USD.

Personally, the dial condition is a deal breaker, but you do you.

I hope this helps!
