I need some help in identifying the following tools. The one with the Nickel base has Elgin written on the bottom of the base, the two with the knurled knobs have Levin printed on them, the two other ones look like lathe collets to me, but they have no inside thread for the drawbar. Any help would be appreciated. I will have to post three seprate images, as I don't know how to send them as a group.

These look like wrist watch size mainspring winders.

Thanks for your Id of these tools. I had an idea they might be, but never having worked on wristwatches,I was not real sure.
