Can someone describe, or better yet post a picture here, of what Howard describes as a "Jurgenson Lip" on Keystone watch cases? Posted below is an estimate of what this feature adds to the case value taken from "American Pocket Watches, Revised 1999", by Meggers and Erhardt.

Mike,
Jurgenson lips refers to 14K cases with the lips part being small pieces that are built into the front and back lids of a DHB&B case. When closed they help form part of the pendant urn and stop short of the first turned piece of the pendant. I don't have one at this time, but here is a picture of one thats in the closed position, from an old post, that you will have to use your imigination to see what I B talkin bout

Finally found a good picture of the "stubby" little jurgenson lips for you;

Thanks, Buster! I understand perfectly because I NOW know that I have one of those cases. I'd describe them as small, half-round protrusions (lips) located at the tip of the front and back lids of a HC movement that come together and clasp the stem. Your picture above shows the lip of the front lid well enough.
While unique, I'd describe them as useless gimmicks when new. I, however, love my new lips Thanks again!
Mike
