Unify edge length

[esha]

Hi there, I've been using Wings for a while but found my way here only now.
And I have already a question:

I've modelled a bracelet around the arm of an existing human figure.
The topology turned out a bit uneven, some polys are wider than others.
Is there a way to make all edges along the rim the same length, without changing the overall diameter?
Basically I'm looking for a way to distribute the verts along the edge more evenly, all at the same distance to each other.
