That post isn't fixed and is threaded and attached to the crown. You can remove it.They unfortunately wont work for the bezel gear though that annoying fixed post on the crown makes it too long for the stems as they can only be adjusted by so much
One would be fine of course for the winding stem.
I have some fat ones with no posts on the crown.
I don't suppose you know of any more? Looks like they're all sold out now.
I don't suppose you know of any more for sale? Just checked the link and they're now sold out.
