Swan neck

[brian7836]

What is the purpose of the swan neck?

[hyster]

It holds in place and allows adjustment of the regulator arm of the movement, as far as I know anyway.

[chubbchubb]

As Hyster said, it facilitates fine regulation of the movement.

[PAMman]

The 'swan neck' is a spring that places pressure on one side of the regulator needle and the pressure on the other side comes from a small screw. Therefore adjusting the screw moves the regulator in smaller increments than would normally be possible without this system. It's functional and also pretty.
