Elgin Factory FEMALE #3 crown post / winding arbor for 6/0s grade 760, 761, 762

One Elgin factory FEMALE #3 crown post for 6/0s grade 760, 761, 762 and perhaps others as well, for movements in waterproof cases, 711-3-D, new in packaging. This is not the stem but rather the female part that screws into the crown and then slides or snaps into the stem. These are sized to allow for a fit across many different cases which is why they'll probably work on almost any Elgin that needs a female crown post to connect to a make waterproof stem. See images for further details. I likely have several of these so the one you get may differ slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
