They are movement holders used by watchmakers when working on watches. I use them when servicing watches so I don't have to handle the freshly cleaned watch parts with my fingers so much and lowers the risk of dropping a movement.
There is also a watch hand holding tool used when fitting (broaching) watch hands. It is the thing in the box with the white sticker on it.
